Fortunately,<b>The \"tools\" for regulating the real estate market are constantly enriching, and a series of measures such as land, finance, administrative measures, market rectification, fiscal and taxation are forming a strong synergy</b>。 It is believed that with the establishment and improvement of the long-term mechanism of real estate, the real estate market will usher in a good situation of healthier development.</p>\n<div class=\"bt-text\">\n\n\n<p> source：<a href=\"https://www.gelonghui.com/p/479661\">经济日报</a></p>\n\n\n</div>\n</article>\n</div>\n</body>\n</html>\n","type":0,"thumbnail":"https://static.tigerbbs.com/c3c5822c22b6cfd1d0ae2625b7bc085e","relate_stocks":{"09979":"绿城管理控股"},"source_url":"https://www.gelonghui.com/p/479661","is_english":false,"share_image_url":"https://static.laohu8.com/e9f99090a1c2ed51c021029395664489","article_id":"1109676905","content_text":"各地调控措施还在密集出台，不断“打补丁”“堵漏洞”。其原因在于一些城市依然面临房价和地价增长过快、市场预期不稳的状况。这对幻想房价过快上涨的炒房客们是持续的威慑。\n\n楼市调控持续加码。仅8月5日一天，就有杭州、北京、成都三城推出房地产调控新规。\n杭州进一步抬高了购房门槛。新举措明确，取得杭州户口未满5年，需缴纳两年社保，可在限购区域购买一套住房；“非户籍+4年社保”的要求让非杭州户籍购房者买房难度加大。杭州调控新规抬高购房门槛目的在于打击短期投资客。此外，杭州还规定新房摇号中签率低的房源，按照社保缴纳月数依次排序，此举旨在避免过多购房者扎堆抢购。\n\n与此同时，成都将赠与住房计入受赠人家庭住房总套数审核购房资格。也就是说，通过赠与方式规避限购的漏洞被彻底堵住了。\n\n而北京的规定更具针对性，直接将调控重点放在打击通过“假离婚”获取购房资格上。新规明确，夫妻离异的，原家庭在离异前拥有住房套数不符合商品住房限购政策规定的，自离异之日起3年内，任何一方均不得购买商品住房。近年来，在一些热点城市，由于限购政策不断收紧，一些人为了获取购房资格，可谓绞尽脑汁。为避开限购，获得再购房的资格，以及享受购买首套住房的低首付款和低贷款利率，一些家庭甚至选择离婚再购房。北京新规让通过“假离婚”进行购房的难度加大，有利于封堵“假离婚”炒房漏洞。\n\n各地调控措施还在密集出台，不断“打补丁”“堵漏洞”。其原因在于一些城市依然面临房价和地价增长过快、市场预期不稳的状况。不断出台的调控措施对于那些依然对房价过快上涨抱有幻想的炒房客们是持续的威慑。\n虚火不灭，楼市调控就需保持高压，更需持续且稳定执行的长效政策，以便购房者对房价走势、购房时点有更稳定的预期。密集出台的调控措施表明，对房地产调控负有主体责任的地方政府，实施楼市调控的主动性和积极性都在增加。今年以来，住房和城乡建设部已多次约谈地方政府，并将这些城市纳入房地产市场监测重点城市名单。对于地方政府而言，“房住不炒”及“不将房地产作为短期刺激经济的手段”的定位应始终坚持。\n日前召开的中央政治局会议强调，要坚持房子是用来住的、不是用来炒的定位，稳地价、稳房价、稳预期，促进房地产市场平稳健康发展。我国提出建立房地产长效机制以来，稳地价、稳房价、稳预期取得明显成效，表明采取的措施符合市场发展规律，精准有效。当个别城市出现过热苗头，须果断加大房地产市场调控力度和监管力度。可喜的是，房地产市场调控的“工具”在不断丰富，土地、金融、行政措施、市场整顿、财税等一系列措施，正在形成强大合力。相信随着房地产长效机制建立和完善，房地产市场将迎来更加健康发展的良好局面。","news_type":1,"symbols_score_info":{"09979":0.9}},"isVote":1,"tweetType":1,"viewCount":2151,"authorTweetTopStatus":1,"verified":2,"comments":[],"imageCount":0,"langContent":"EN","totalScore":0},{"id":152958607,"gmtCreate":1625265952809,"gmtModify":1703739508025,"author":{"id":"3568614602734225","authorId":"3568614602734225","name":"洞幽烛远","avatar":"https://static.tigerbbs.com/0e72968722642d797ced5fcb63f2fec1","crmLevel":11,"crmLevelSwitch":0,"followedFlag":false,"authorIdStr":"3568614602734225","idStr":"3568614602734225"},"themes":[],"htmlText":"Ok","listText":"Ok","text":"Ok","images":[],"top":1,"highlighted":1,"essential":1,"paper":1,"likeSize":2,"commentSize":0,"repostSize":0,"link":"https://ttm.financial/post/152958607","repostId":"2148808400","repostType":4,"repost":{"id":"2148808400","kind":"news","pubTimestamp":1625238620,"share":"https://ttm.financial/m/news/2148808400?lang=en_US&edition=fundamental","pubTime":"2021-07-02 23:10","market":"us","language":"zh","title":"From the Tesla recall incident, a glimpse of the true face of OTA car evolution","url":"https://stock-news.laohu8.com/highlight/detail?id=2148808400","media":"脑极体","summary":"特斯拉在科技圈中，是个有话题有热点的黑网红，曝出来的永远都是各种控制系统失控出车祸的新闻，这不最近又闯祸了。近日消息，特斯拉召回部分进口和国产Model 3、国产Model Y电动汽车，共计28552","content":"<p><a href=\"https://laohu8.com/S/TSLA\">Tesla</a>In the science and technology circle, it is a black online celebrity with hot topics. What is exposed is always the news of various control systems getting out of control and causing car accidents, which has caused trouble again recently. According to recent news, Tesla recalled some imported and domestically produced Model 3 and domestically produced Model Y electric vehicles, totaling 285,520 vehicles. The main reason for the recall is that the vehicles have potential safety hazards in the active cruise control system, which can easily cause the driver to turn or be in D gear. Accidentally activating the active cruise function may lead to a sudden increase in vehicle speed, which may lead to vehicle collisions in extreme cases.</p><p>It looks very scary. After all, it is related to car safety. Tesla's large-scale recall is not a way to physically return the car to the factory for rebates, but through the technology of remotely upgrading the OTA of the car, users can complete the online upgrade without going to the store. Can the seemingly serious security hazard be solved just by updating the security package through OTA? This recall method, without the follow-up routine safety test of the car manufacturer, always feels uneasy, and even makes people have doubts about the safety of OTA technology itself. So is the OTA system safe after all? To answer this question, let's start with what an OTA car is.</p><p><b>What exactly is an OTA car?</b></p><p>The full name of OTA is \"Over-The-Air\", which means Over-The-Air download technology (remote upgrade technology), a technology that downloads data packets through wireless networks to update the system and improve terminal functions and services. Our computers and mobile phones also use this OTA technology when updating the system. The purpose of OTA system upgrade is to fix system vulnerabilities, optimize and improve to obtain more functions, performance improvement, or visual effect improvement, and this update is through online detection, version matching, download new code to the local area after networking, and then execute installation, verification and other procedures.</p><p><img src=\"https://static.tigerbbs.com/404652f159ffcb9982e091e353fdade0\" tg-width=\"868\" tg-height=\"538\" referrerpolicy=\"no-referrer\"></p><p>The first application of OTA technology was in the ModeL S launched by Tesla in 2012. The content update scope includes human-computer interaction, autonomous driving, power battery system and other modules. At that time, Tesla could complete key card vulnerabilities through OTA. Improve cruising range, improve maximum speed, improve ride comfort, etc.</p><p>Automotive OTA technology can be divided into SOTA (Software OTA, software over-the-air upgrade) and FOTA (Firmware OTA, firmware over-the-air upgrade) according to the difference of upgraded firmware, that is, vehicle OTA. Among them, SOTA can only update vehicle application layer software, limited to vehicle machine, infotainment and other software, and has almost no hardware scheduling capabilities. It is less difficult for car companies to implement it. Most of the OTA cars often advertised on the market are only with SOTA technology. FOTA upgrades the system layer of the vehicle controller, which affects the vehicle's power system, battery management and other systems. For example, it can update the OS layer software of the underlying systems such as chassis, power, and ADAS.</p><p>The main difference between cars equipped with OTA technology and traditional cars is: in terms of performance, cars equipped with OTA technology have richer on-board functions. Generally speaking, they realize functions from these aspects: they can fix system bugs, update drivers, optimize UI interface, delete problematic apps, upgrade major versions, etc. Most automotive OTAs generally launch online system updates for entertainment systems, navigation, etc.</p><p>Secondly, when the vehicle encounters software failure or needs to be updated, the traditional car needs to drive the car to a 4S shop and use a professional computer to repair it, which takes time and energy. However, the car equipped with OTA technology can complete the vehicle upgrade and repair problems without leaving home, saving costs and time. For example, OTA cars can update the ECU software of the car. ECU is the automobile electronic controller. In layman's terms, it is the brain of the car. When a new car leaves the factory, the power will not be fully exerted, usually leaving some room for improvement. Brushing the ECU is to use some technical means to encode the ECU on the basis of the original engine's ability to bear it to achieve the purpose of increasing horsepower or torque. Traditional cars need to rely on the original technology to brush the ECU, and OTA cars can upgrade this capability online.</p><p>From the above description, it can be seen that the functions and convenience of vehicles equipped with OTA technology are exciting and favorable, but because OTA technology itself involves changes in vehicle physical properties such as ECU changes, battery performance changes, and vehicle software experience functions, among them, some reefs may be touched.</p><p><b>OTA cars are a double-edged sword</b></p><p>Judging from the conservative choice of traditional car companies, there is a reason why people don't accept all these wonderful experiences according to the order, and they are not so keen on carrying them. OTA cars are also a double-edged sword.</p><p><img src=\"https://static.tigerbbs.com/b9e367c30b535b8c2a265e8ccd88751a\" tg-width=\"1000\" tg-height=\"616\" referrerpolicy=\"no-referrer\"></p><p>First of all, because of the mature R&D cycle and stable enterprise structure of traditional automobiles, there are too many newly matched components to realize OTA, and the cost of changing production lines and enterprise structures is too high. These new components need to undergo high-cost tests. After testing, automobile manufacturers will not integrate a bunch of untested \"semi-finished products\" and put them on the market, which will affect the safety of lives and property.</p><p>From the analysis of technical reasons, it is mainly related to the structure of traditional cars. Traditional cars are purely mechanical structures, and the power unit is very complex. The parameters such as fuel injection volume, braking system, shift logic, steering ratio, and suspension style are calibrated, and they need to be debugged and tested by engineers tens of millions of times to the best safe state before they can leave the factory. However, rebuilding OTA becomes unstable for power output and destroys the balanced parameter settings.</p><p>In addition to the security risks of physical hardware devices, OTA technology is at risk of being hacked during the remote upgrade process. In the process of downloading the upgrade package of the car, hackers can use network means to send the virus upgrade package to the vehicle, and then modify the system, remotely control and extort money. If you encounter some extreme weather or unstable environmental network, it will also lead to vulnerabilities in the upgrade package, which will cause the vehicle upgrade to fail.</p><p>We can see that OTA technology needs to go through a lot of security tests in the matching of physical equipment components themselves, as well as in the protocol and design process. No matter which link there is hidden danger in the link coupling between software and hardware devices, it is a matter of life and death for the safety of enterprises and vehicles. The problem cannot be played with. Take this recall of Tesla as an example. For the operation of ACC adaptive cruise control, the conventional design scheme of car companies is to use push-button or independent lever operation to turn on the adaptive cruise function. However, Tesla is prone to misoperation when using the adaptive cruise control function, which is a design logic defect. Tesla's solution is to raise the threshold of activating active cruise and add reminders of its activation and exit to avoid the possible recurrence of accidental touch.</p><p>If the logic setting of a small function is wrong, it will also bring irreparable results. Regarding safety issues, we cannot assume that everyone is cautious and does not have a short-circuit in their brains. If it is not uncommon to pay attention to vehicle-related news recalls, OTA can solve some software faults through upgrades, but whether it will bring new problems will also be an urgent problem to be solved. It can be seen that OTA technology is a double-edged sword for car companies, and it is meaningless to discuss whether it is absolutely safe. The road to intelligence of OTA cars will not be achieved overnight. Some system flaws need time to gradually iteratively optimize. After all, there is no product. It is perfect from the beginning of design.</p><p><img src=\"https://static.tigerbbs.com/e094f51a71e4d181f644eb1da3c657c5\" tg-width=\"1080\" tg-height=\"643\" referrerpolicy=\"no-referrer\"></p><p>At present, the development trend of the entire market is that car companies are gradually embracing OTA technology, and will not give up food because of local restrictions. OTA technology is becoming the standard feature of smart cars, and its technology penetration rate is particularly obvious. Statistics show that 30% of vehicles sold worldwide in 2020 have OTA functions. It will rise to 79% by 2025. According to data released by the Gaogong Intelligent Automobile Research Institute, the OTA installation rate of new cars in the Chinese market has reached 22.42% in 2020, and is expected to increase to 35-40% this year.</p><p>Although many car companies are trying their best to market OTA upgrade technology at the press conference, there are also many people swimming naked. Most car companies still stay at the SOTA upgrade level, that is, the functional upgrade at the entertainment and interaction level. There are only a handful of car companies that can upgrade the whole vehicle OTA. At present, upstarts such as Tesla, Ideal, XPeng, etc. have vehicle OTA capabilities. The OTA upgrade for the whole vehicle is a very significant sign that smart cars are different from traditional cars. From the perspective of the development history of OTA vehicles, the demand for OTA in the automotive industry is gradually developing from the parts level, vehicle level, and enterprise level to the industry ecological level. Traditional car companies such as BMW, Volkswagen, and SAIC-GM are actively reforming and reconstructing their electronic architecture in this major change to realize vehicle OTA.</p><p><b>The road to the future test of OTA cars</b></p><p>Nowadays, most car companies can achieve OTA of car-machine entertainment systems, that is, SOTA, but the real hard nut to crack is the whole vehicle FOTA. Because it involves the electronic architecture, hardware configuration and software self-research capabilities of vehicle manufacturers in new cars. The electronic controller needs to be deeply integrated with the update mechanism of the equipment. In what state the vehicle is flashed and written, and how to ensure the stability and safety of the update process. These implementation difficulties must be considered. For example, there are hundreds of ECUs (automotive electronic control components) of automobile interior components in the architecture of the whole vehicle, and they are connected in different communication networks. The data transmission protocols of each network are different and complicated. The more the upgraded controller considers, the more difficult it is to double the network communication topology protocols. OTA suppliers need to have a clear understanding of the characteristics of each communication line in order to efficiently realize software upgrades.</p><p><img src=\"https://static.tigerbbs.com/5529364f1b506bceb17619a2c75f3112\" tg-width=\"1080\" tg-height=\"600\" referrerpolicy=\"no-referrer\"></p><p>In terms of information security, in the process of OTA data transmission, there are potential risks of being counterfeited, stolen, and attacked. During the communication process, it will be held hostage and tampered with by malicious hackers, which may lead to abnormal vehicle operation, privacy leakage, financial and even life safety is threatened. It is particularly important to ensure the safety upgrade of OTA cars. OTA automobile manufacturers need to build a well-designed identification key technology architecture, and the limitation of verification mechanism and upgrade conditions requires two-way control to ensure an information security system integrating device and cloud.</p><p>The realization of OTA car functions relies on the development of various capabilities such as gateway protocols, network security, and continuous development of computing algorithm technology. Although electronic modules and software technologies develop together and are more and more applied in complete vehicles, the technology is still not mature. At the stage of widespread social recognition, the development of smart cars is long and long, and there is still a lot of room for updates and improvements. The optimization of OTA car functions and service differentiation need to evolve simultaneously. Fortunately, we will witness the surprises brought by OTA cars together.</p>","source":"lsy1577414888172","collect":0,"html":"<!DOCTYPE html>\n<html>\n<head>\n<meta http-equiv=\"Content-Type\" content=\"text/html; charset=utf-8\" />\n<meta name=\"viewport\" content=\"width=device-width,initial-scale=1.0,minimum-scale=1.0,maximum-scale=1.0,user-scalable=no\"/>\n<meta name=\"format-detection\" content=\"telephone=no,email=no,address=no\" />\n<title>From the Tesla recall incident, a glimpse of the true face of OTA car evolution</title>\n<style type=\"text/css\">\na,abbr,acronym,address,applet,article,aside,audio,b,big,blockquote,body,canvas,caption,center,cite,code,dd,del,details,dfn,div,dl,dt,\nem,embed,fieldset,figcaption,figure,footer,form,h1,h2,h3,h4,h5,h6,header,hgroup,html,i,iframe,img,ins,kbd,label,legend,li,mark,menu,nav,\nobject,ol,output,p,pre,q,ruby,s,samp,section,small,span,strike,strong,sub,summary,sup,table,tbody,td,tfoot,th,thead,time,tr,tt,u,ul,var,video{ font:inherit;margin:0;padding:0;vertical-align:baseline;border:0 }\nbody{ font-size:16px; line-height:1.5; color:#999; background:transparent; }\n.wrapper{ overflow:hidden;word-break:break-all;padding:10px; }\nh1,h2{ font-weight:normal; line-height:1.35; margin-bottom:.6em; }\nh3,h4,h5,h6{ line-height:1.35; margin-bottom:1em; }\nh1{ font-size:24px; }\nh2{ font-size:20px; }\nh3{ font-size:18px; }\nh4{ font-size:16px; }\nh5{ font-size:14px; }\nh6{ font-size:12px; }\np,ul,ol,blockquote,dl,table{ margin:1.2em 0; }\nul,ol{ margin-left:2em; }\nul{ list-style:disc; }\nol{ list-style:decimal; }\nli,li p{ margin:10px 0;}\nimg{ max-width:100%;display:block;margin:0 auto 1em; }\nblockquote{ color:#B5B2B1; border-left:3px solid #aaa; padding:1em; }\nstrong,b{font-weight:bold;}\nem,i{font-style:italic;}\ntable{ width:100%;border-collapse:collapse;border-spacing:1px;margin:1em 0;font-size:.9em; }\nth,td{ padding:5px;text-align:left;border:1px solid #aaa; }\nth{ font-weight:bold;background:#5d5d5d; }\n.symbol-link{font-weight:bold;}\n/* header{ border-bottom:1px solid #494756; } */\n.title{ margin:0 0 8px;line-height:1.3;color:#ddd; }\n.meta {color:#5e5c6d;font-size:13px;margin:0 0 .5em; }\na{text-decoration:none; color:#2a4b87;}\n.meta .head { display: inline-block; overflow: hidden}\n.head .h-thumb { width: 30px; height: 30px; margin: 0; padding: 0; border-radius: 50%; float: left;}\n.head .h-content { margin: 0; padding: 0 0 0 9px; float: left;}\n.head .h-name {font-size: 13px; color: #eee; margin: 0;}\n.head .h-time {font-size: 12.5px; color: #7E829C; margin: 0;}\n.small {font-size: 12.5px; display: inline-block; transform: scale(0.9); -webkit-transform: scale(0.9); transform-origin: left; -webkit-transform-origin: left;}\n.smaller {font-size: 12.5px; display: inline-block; transform: scale(0.8); -webkit-transform: scale(0.8); transform-origin: left; -webkit-transform-origin: left;}\n.bt-text {font-size: 12px;margin: 1.5em 0 0 0}\n.bt-text p {margin: 0}\n</style>\n</head>\n<body>\n<div class=\"wrapper\">\n<header>\n<h2 class=\"title\">\nFrom the Tesla recall incident, a glimpse of the true face of OTA car evolution\n</h2>\n<h4 class=\"meta\">\n<p class=\"head\">\n<strong class=\"h-name small\">脑极体</strong><span class=\"h-time small\">2021-07-02 23:10</span>\n</p>\n</h4>\n</header>\n<article>\n<p><a href=\"https://laohu8.com/S/TSLA\">Tesla</a>In the science and technology circle, it is a black online celebrity with hot topics.

According to data released by the Gaogong Intelligent Automobile Research Institute, the OTA installation rate of new cars in the Chinese market has reached 22.42% in 2020, and is expected to increase to 35-40% this year.</p><p>Although many car companies are trying their best to market OTA upgrade technology at the press conference, there are also many people swimming naked. Most car companies still stay at the SOTA upgrade level, that is, the functional upgrade at the entertainment and interaction level. There are only a handful of car companies that can upgrade the whole vehicle OTA. At present, upstarts such as Tesla, Ideal, XPeng, etc. have vehicle OTA capabilities. The OTA upgrade for the whole vehicle is a very significant sign that smart cars are different from traditional cars. From the perspective of the development history of OTA vehicles, the demand for OTA in the automotive industry is gradually developing from the parts level, vehicle level, and enterprise level to the industry ecological level. Traditional car companies such as BMW, Volkswagen, and SAIC-GM are actively reforming and reconstructing their electronic architecture in this major change to realize vehicle OTA.</p><p><b>The road to the future test of OTA cars</b></p><p>Nowadays, most car companies can achieve OTA of car-machine entertainment systems, that is, SOTA, but the real hard nut to crack is the whole vehicle FOTA. Because it involves the electronic architecture, hardware configuration and software self-research capabilities of vehicle manufacturers in new cars. The electronic controller needs to be deeply integrated with the update mechanism of the equipment. In what state the vehicle is flashed and written, and how to ensure the stability and safety of the update process. These implementation difficulties must be considered. For example, there are hundreds of ECUs (automotive electronic control components) of automobile interior components in the architecture of the whole vehicle, and they are connected in different communication networks. The data transmission protocols of each network are different and complicated. The more the upgraded controller considers, the more difficult it is to double the network communication topology protocols. OTA suppliers need to have a clear understanding of the characteristics of each communication line in order to efficiently realize software upgrades.</p><p><img src=\"https://static.tigerbbs.com/5529364f1b506bceb17619a2c75f3112\" tg-width=\"1080\" tg-height=\"600\" referrerpolicy=\"no-referrer\"></p><p>In terms of information security, in the process of OTA data transmission, there are potential risks of being counterfeited, stolen, and attacked. During the communication process, it will be held hostage and tampered with by malicious hackers, which may lead to abnormal vehicle operation, privacy leakage, financial and even life safety is threatened. It is particularly important to ensure the safety upgrade of OTA cars. OTA automobile manufacturers need to build a well-designed identification key technology architecture, and the limitation of verification mechanism and upgrade conditions requires two-way control to ensure an information security system integrating device and cloud.</p><p>The realization of OTA car functions relies on the development of various capabilities such as gateway protocols, network security, and continuous development of computing algorithm technology. Although electronic modules and software technologies develop together and are more and more applied in complete vehicles, the technology is still not mature. At the stage of widespread social recognition, the development of smart cars is long and long, and there is still a lot of room for updates and improvements. The optimization of OTA car functions and service differentiation need to evolve simultaneously. Fortunately, we will witness the surprises brought by OTA cars together.</p>\n<div class=\"bt-text\">\n\n\n<p> source：<a

3、国产Model Y电动汽车，共计285520辆，召回的主要原因是车辆存在主动巡航控制系统安全隐患，易造成驾驶员在转弯或者在D挡位情形误激活主动巡航功能，可能出现车辆速度突增情形，极端情况下可能导致车辆发生碰撞。\n看起来非常吓人，毕竟是关系到用车安全的问题。特斯拉此次的大规模召回不是物理上将车返厂返点的方式，而是通过汽车远程升级OTA的技术，用户无需到店即可完成在线升级。看似很严重的安全隐患仅仅通过OTA升级安全包的更新就可以解决问题吗？这种召回方式，没有车厂后续的常规安全测试，总觉得让人不安，甚至也会让人对OTA技术本身是否安全有疑虑。那么OTA系统到底安全吗？想要回答这个问题，先从什么是OTA汽车聊起。\nOTA汽车到底是什么？\nOTA的全称“Over-The-Air”，即空中下载技术（远程升级技术），通过无线网络下载数据包从而对系统更新进而改善终端功能和服务的技术。我们的电脑和手机进行系统更新的时候也是用的这个OTA技术。OTA进行系统升级的目的就是修复系统漏洞、优化改善以获得更多的功能、性能提升，又或者是视觉效果的改善，且这种更新是通过联网后在线检测、匹配版本、下载新的代码到本地进而执行安装、校验等程序。\n\nOTA技术最早应用于的汽车就是在2012年特斯拉推出的ModeL S上，内容更新范围包括人机交互、自动驾驶、动力电池系统等模块，当时特斯拉可以通过OTA完成钥匙卡漏洞、提升续航里程、提高最高速度、提升乘坐舒适度等。\n汽车OTA技术根据升级固件的差异，可以分为SOTA（Software OTA，软件空中升级）和FOTA（Firmware OTA，固件空中升级），即整车OTA。其中，SOTA只能对车辆应用层软件更新，仅限车机、信息娱乐等软件，几乎没有硬件调度的能力，车企实现难度较小，市面上经常看到宣传的OTA汽车大多数都是仅具有SOTA技术。而FOTA是对车辆控制器的系统层进行升级，影响的是车的动力系统、电池管理等系统，比如可以对底盘、动力、ADAS等底层系统进行OS层的软件更新。\n搭载OTA技术的汽车跟传统的汽车主要的区别是：在性能方面，搭载OTA技术的汽车车载实现的功能更丰富，总的来说是从这几方面实现功能：可以修复系统bug，更新驱动，优化UI界面，删除问题APP，大版本升级等。大多数车用OTA一般是针对娱乐系统、导航等推出在线系统更新。\n其次是车辆遇到软件故障或是需要更新时，传统汽车需要将车开到4S店利用专业电脑修复，耗费的时间精力，而搭载OTA技术的汽车可以足不出户就完成车辆升级，修复问题，节省成本与时间。比如OTA汽车可以对汽车的ECU软件进行更新。ECU是汽车电子控制器，通俗的来说就是汽车的大脑，新车出厂时动力不会完全发挥出来，通常会留下一部分可提升的空间，刷ECU就是通过一些技术手段，在原厂发动机能承受的基础上对ECU进行编码，达到提升马力或扭矩的目的，传统汽车想要刷ECU需要借助原厂的技术，OTA汽车可以在线升级这种能力。\n从上述的描述可以看出搭载OTA技术的车辆实现的功能以及便捷性让人心动与青睐，但是因为OTA技术本身涉及到对车辆物理性能比如ECU改变、电池性能改变、以及车辆软件体验功能的改变，在这其中，也有一些暗礁可能被触及。\nOTA汽车是把双刃剑\n从传统车企的保守选择来看，大家没有照单全收这些美好的体验，没有那么热衷搭载也是有原因的，OTA汽车也是把双刃剑。\n\n首先是因为传统汽车成熟的研发周期和稳定的企业架构，想要实现OTA需要新匹配的元器件太多，产线与企业结构的改变成本太大，这些新的元器件都需要经过高成本的测试，汽车厂商不会将一堆未经测试考验的“半成品”集成后推向市场，影响生命财产安全。\n从技术原因分析来看，主要是跟传统汽车的结构有关。传统的汽车都是纯机械结构，动力单元非常复杂，喷油量、刹车系统、换挡逻辑、转向比、悬挂风格等参数关系标定，需要被工程师千万次调试测试到最佳安全状态才能出厂。而重新搭建OTA对于动力输出来说变得不稳定，破坏平衡的参数设定。\n除了因为物理硬件设备的安全隐患外，OTA技术在远程升级过程中，有被黑客攻击的风险。汽车在下载升级包的过程中，黑客可以利用网络手段将被病毒升级包发送给车辆，进而修改系统、远程控制、勒索钱财。如果遇到一些极端天气或者环境网络不稳定的情况，也会导致升级包出现漏洞，进而使得车辆升级失败。\n我们可以看到OTA技术在物理设备元器件本身的匹配以及协议和设计过程需要经过大量的安全测试，软硬件设备之间的链接耦合无论是哪个环节存在隐患，对于企业和车辆的安全都是生死存亡的问题，不能儿戏。拿特斯拉汽车此次召回事件来说，ACC自适应巡航控制的操作,常规的车企设计方案是采用按键式或者独立拨杆的操作开启自适应巡航功能，但是特斯拉在使用自适应巡航控制功能的时候容易有误操作，这是一个设计逻辑上的缺陷，特斯拉的解决方案是提升激活主动巡航的阈值，加入了其激活和退出的提醒，避免误触的可能再发生。\n小小的一个功能逻辑设定有误的话，也会带来万劫不复的结果，对于安全问题，不能假设所有人都是小心谨慎没有大脑短路的时候。如果关注车辆相关的的新闻召回事件屡见不鲜，对于软件故障，OTA可以通过升级可以解决部分故障，但是是否还会带来新的问题，也会是个亟待解决的问题。可以看到OTA技术对于车企而言，是把双刃剑，讨论其是否绝对安全也没有意义，OTA汽车的智能化之路，不会一蹴而就，一些系统的瑕疵需要时间去逐渐迭代优化，毕竟没有任何产品在设计之初就是完美的。\n\n目前整个市场发展的趋势就是车企逐渐在拥抱OTA技术，不会因为局部的限制因噎废食。OTA技术正成为智能汽车标配， 其技术渗透率提升尤为明显。有数据显示，在2020年全球售出的车辆中，有30％具有OTA功能。到2025年，该比例将上升至79％。而根据高工智能汽车研究院发布的数据，2020年中国市场新车OTA搭载率已经达到22.42%，预计今年将提升至35-40%。\n尽管不少车企在发布会卖力营销OTA升级技术，但裸泳的人也不少，大多数车企还是停留在SOTA升级层面，也就是娱乐互动层面的功能升级，能够进行整车OTA升级的车企屈指可数。目前有着整车OTA能力的是特斯拉、理想、小鹏、等新贵。而面向于整车OTA升级，才是智能汽车区别于传统汽车的一个非常显著的标志。从OTA汽车的发展历程上来看，汽车行业对于OTA的需求是逐步由零部件级、整车级、企业级发展到行业生态级。宝马、大众、上汽通用等传统车企在这个大的变革中积极改革进行电子架构重构，以实现整车OTA。\nOTA汽车未来的大考之路\n现在大部分车企都能做到车机娱乐系统的OTA，也就是 SOTA，但真正难啃的硬骨头是整车FOTA。因为其涉及整车制造商在新车上的电子架构、硬件配置以及软件自研能力。电子控制器需要与设备的更新机制进行深度整合，车辆在什么状态下进行刷写，如何确保确保更新过程的稳定性与安全性，这些实现上的难点都是要考虑的。比如汽车内部件的ECU（汽车电子控制元器件），它们在整车的架构中数量为几百个，连接在不同的通讯网络中，每条网络的数据传输协议不同，比较复杂，升级的控制器越多考量的网络通讯拓扑结构协议翻番难度上升，需要OTA供应商对每条通讯线路的特点有清晰的认知才能高效地实现软件升级。\n\n在信息安全方面，OTA数据传输的过程中，有被仿冒、窃取、攻击的潜在风险，在通讯过程中会被不怀好意的黑客挟持与篡改，可能导致车辆运行异常、隐私泄露、财务甚至是生命安全受到威胁。保障OTA汽车的安全升级之路尤为重要。OTA汽车厂商需要搭建设计完善的标识秘钥技术架构，验证机制与升级条件的限定需要双向把控，才能保障端云一体的信息安全体系。\nOTA汽车功能的实现背后依托网关协议、网络安全、算力算法技术持续开发等多方面能力发展，虽然电子模块与软件技术协同发展，在整车上应用的越来越多，但技术还是没有成熟到社会广泛认同的阶段，智能汽车的发展之路长途漫漫，更新和改善的空间还是很大，OTA汽车功能上的优化，服务的差异化需要同步进化，幸运的是我们会一起见证OTA汽车带来的惊喜。","news_type":1,"symbols_score_info":{"TSLA":0.9}},"isVote":1,"tweetType":1,"viewCount":2280,"authorTweetTopStatus":1,"verified":2,"comments":[],"imageCount":0,"langContent":"EN","totalScore":0},{"id":150517724,"gmtCreate":1624921505068,"gmtModify":1703847769587,"author":{"id":"3568614602734225","authorId":"3568614602734225","name":"洞幽烛远","avatar":"https://static.tigerbbs.com/0e72968722642d797ced5fcb63f2fec1","crmLevel":11,"crmLevelSwitch":0,"followedFlag":false,"authorIdStr":"3568614602734225","idStr":"3568614602734225"},"themes":[],"htmlText":"Nice","listText":"Nice","text":"Nice","images":[],"top":1,"highlighted":1,"essential":1,"paper":1,"likeSize":1,"commentSize":0,"repostSize":0,"link":"https://ttm.financial/post/150517724","repostId":"2146002531","repostType":4,"isVote":1,"tweetType":1,"viewCount":2346,"authorTweetTopStatus":1,"verified":2,"comments":[],"imageCount":0,"langContent":"EN","totalScore":0},{"id":128080212,"gmtCreate":1624495318936,"gmtModify":1703838254342,"author":{"id":"3568614602734225","authorId":"3568614602734225","name":"洞幽烛远","avatar":"https://static.tigerbbs.com/0e72968722642d797ced5fcb63f2fec1","crmLevel":11,"crmLevelSwitch":0,"followedFlag":false,"authorIdStr":"3568614602734225","idStr":"3568614602734225"},"themes":[],"htmlText":"Thanks.","listText":"Thanks.","text":"Thanks.","images":[],"top":1,"highlighted":1,"essential":1,"paper":1,"likeSize":0,"commentSize":0,"repostSize":0,"link":"https://ttm.financial/post/128080212","repostId":"2145086880","repostType":4,"repost":{"id":"2145086880","kind":"news","pubTimestamp":1624415733,"share":"https://ttm.financial/m/news/2145086880?lang=en_US&edition=fundamental","pubTime":"2021-06-23

The real interest rate is equal to the nominal interest rate minus inflation expectations. When the nominal interest rate falls, gold continues to fall, and the price of gold has always had an inverse relationship with the real interest rate of the US Treasury Bond</b>That is to say, the real interest rate actually rises when the nominal interest rate falls, which can only show that the expectation of deflation is indeed relatively strong;</p><p><b>4. Expectations for a unilateral rise in commodities seem to no longer exist</b>, taking copper as an example, copper inventories on the London Metal Exchange increased by 24,925 tons, a surge of 17%. After a circle of research, it is said that it is because the supply and demand of copper itself are not so good. The reason why copper prices are strong depends largely on loose liquidity support. Under the expectation of price increases, the industrial chain buys up but not down, and inventories are all hidden, but now the Fed's rate hike expectations have advanced ahead of schedule, and the State Reserve has also sold inventories directly to downstream companies. When the price increase expectations are gone, the hidden inventories of hoarding goods are directly explicit, and the price increase expectations have been shaken.</p><p><b>5. Judging from the recent performance of the U.S. stock market, the market style preferences of U.S. stocks have also undergone significant changes, with the Nasdaq significantly outperforming the Dow</b>, the performance of growth is significantly stronger than cycle and value.</p><p>So, the question is, what happened to make market expectations change so quickly?</p><p>To answer this question, let's briefly analyze how inflation came about.</p><p><b>1. The origin of inflation</b></p><p>There is an essential difference between this round of quantitative easing in the United States and the 2008 financial crisis.</p><p>This time, the United States directly distributed the bills released by the Federal Reserve to residents through fiscal stimulus, while the quantitative easing of the 2008 financial crisis gave banknotes to financial institutions to help them deal with bad debts and illiquid assets.</p><p>Giving banknotes to residents can directly create aggregate demand, while giving banknotes to financial institutions can only create aggregate demand after the entity has financing needs.</p><p>Since the demand stimulation mode of helicopter money is divorced from the traditional historical experience, the speed of production adjustment is slower than the speed of demand expansion, which leads to supply chain bottlenecks and shortage of commodities at the production end.</p><p>Looking at the data of the US inventory-to-sales ratio can illustrate some problems. The seasonally adjusted inventory-to-sales ratio of retailers is the lowest, only 1.07, and the inventory of wholesalers is also relatively low, at 1.22. However, the inventory-to-sales ratio of manufacturers is as high as 1.48, which is still at a high level.</p><p><img src=\"https://static.tigerbbs.com/48ebb5dc27d1a4d9b56b06e650782960\" tg-width=\"590\" tg-height=\"375\" referrerpolicy=\"no-referrer\"></p><p>What does that mean?</p><p>This shows that after the United States issued welfare benefits, the American people's consumer demand for buy buy was too strong, resulting in retailers being bought out of stock. However, because the labor force is still receiving unemployment benefits, they are unwilling to come back to work, and those who come back to work are also Mainly in the service industry, not the manufacturing industry, coupled with expensive raw materials and tight transportation capacity, production has not recovered much.</p><p>The single-month retail sales data in the United States in May was US $620.2 billion, while the single-month retail sales data in the United States in 2019 was just over US $500 billion. Looking at the industrial production index, it was less than 100 in May, but it was around 102 in 2019.</p><p>In other words, consumption is far above pre-epidemic, but production has not yet returned to pre-epidemic.</p><p><img src=\"https://static.tigerbbs.com/acd06a9419c601db0a7cd0d4b4b66049\" tg-width=\"590\" tg-height=\"375\" referrerpolicy=\"no-referrer\"></p><p>Originally, import suppliers in the United States had more choices. For example, by attacking China's textile industry and pushing up upstream costs, China's industrial chain was forced to move out to places with lower labor costs (India, Southeast Asia). Since consumer demand is good and production is insufficient, how should the gap between supply and demand be met? We can only rely on imports.</p><p>Unexpectedly, the epidemic in India in April disrupted this plan. The epidemic not only appeared in India, but also quickly spread to Southeast Asian countries, Taiwan and Japan. These places are mostly production bases in the world. As a result, China's industrial chain not only did not move out, but instead further concentrated production resources domestically. FDI has recently It is accelerating the inflow into the country.</p><p><img src=\"https://static.tigerbbs.com/453c45b93dd234e782b6886c74a10046\" tg-width=\"589\" tg-height=\"299\" referrerpolicy=\"no-referrer\"></p><p>Since the gap in retail inventory in the United States is rigid, and countries and regions with production capacity have also been shut down due to the new round of epidemic, the gap in consumption and inventory in the United States can basically only be balanced by China's imports.</p><p><img src=\"https://static.tigerbbs.com/d0f6894c423cdb48c2a83c6b2eb33a26\" tg-width=\"588\" tg-height=\"321\" referrerpolicy=\"no-referrer\"></p><p><b>2. Unmovable orders</b></p><p>Now come back and look at the domestic.</p><p>Since China took the lead in controlling the epidemic, subsidized enterprises through credit during the epidemic, and maintained enterprises and production capacity. Therefore, from last year to now, China has been the backbone of stabilizing global inflation. The global supply system is highly dependent on China's production. Shipping costs have increased by more than 4-5 times compared with before the epidemic, and individual stocks related to shipping have also increased several times.</p><p><img src=\"https://static.tigerbbs.com/c2d563c458f06a2b983ad41fdf8636d9\" tg-width=\"588\" tg-height=\"295\" referrerpolicy=\"no-referrer\"></p><p>But looking at the current economic data, the new PMI export orders in May were only 48.3%, which was below the boom-and-dry line. Compared with the previous value of 50.4%, there was a more obvious downward trend. The export growth rate in May was 27.9%, which was not as good as the previous value of 32.3%. Now the market has begun to talk more about the peak of external demand.</p><p>From a logical and factual point of view, companies should not be short of orders, because overseas companies can only rely on China's production capacity at present.</p><p>We tend to think that the decline in new export orders is not because enterprises have no orders, but because enterprises dare not take orders easily.</p><p>Why are enterprises afraid to take orders? The main reason is that upstream commodities are sold too fast, and you lose money when you take orders.</p><p>There are three main reasons for the rapid rise in upstream commodity prices:</p><p>1. The demand of the United States can be printed by printing money. Most non-ferrous metals are priced in US dollars. The downward trend of the US dollar and the expansion of demand itself are good for upstream commodities.</p><p>2. Upstream supply cannot be opened, and some of them are unable to resume work due to the lack of vaccines in emerging markets. The spread of the epidemic in India has exacerbated this trend. For example, the semiconductor supply chain is tight, and the supply of scrap copper and some rare minerals has been disturbed; Some are because trade unions are strong; Others feel that demand is not sustainable. Good short-term demand is only printed by the United States and is not sustainable. Now it will be a matter of three years from the expansion of production capacity to the release of output, but if there is no such good demand in the future, You will lose money, so it is better to take advantage of the current price increase to maintain the oligopoly and earn enough cash flow now.</p><p>3. For domestic commodities with pricing power, due to the \"double carbon\" goal, safe production and other demands, the market is expected to reduce production, resulting in hidden inventories, and the downstream will also expect that supply will be in short supply in the future, so they can only panic stocking up at the moment, which intensifies expectations for upstream price increases.</p><p>From the data point of view, the PPI in May was as high as 9% year-on-year, while the CPI was only 1.3% year-on-year. Both the PMI raw material price minus the price of finished products and the PPI raw material price minus the PPI processing price hit a record high year-on-year, which shows that the downstream production and manufacturing links are constantly enduring upstream inflation.</p><p><img src=\"https://static.tigerbbs.com/bf605a70afe88045b7636a1a9c9e0b19\" tg-width=\"589\" tg-height=\"323\" referrerpolicy=\"no-referrer\"></p><p>But everything must have a degree. When the contradiction of the upstream rise accumulates to a certain extent, the company will \"increase income but not increase profits\" and \"thankless\" for a long time, so naturally it will not dare to take orders, because the more orders it takes, the more money it will lose.</p><p><img src=\"https://static.tigerbbs.com/3e11053c2e74d92908dd4a04aa0cfcda\" tg-width=\"587\" tg-height=\"297\" referrerpolicy=\"no-referrer\"></p><p><b>3. The mysterious interest rate meeting</b></p><p>The most interesting thing about the June interest rate meeting is that Taper, which the market is paying attention to, basically didn't mention much, and the expression was very vague. It only said that the premise of opening Taper is to achieve the goal of \"substantial progress\" in the economy, and the standard of \"substantial progress\" It is determined by the Federal Reserve.</p><p>However, the most surprising thing about the June interest rate meeting was that rate hike's expectations were advanced. The number of members who believe that the rate hike should rise from 4 to 7 in 2022, and the number of members who should rate hike in 2023 will rise from 7 to 13.</p><p>On the whole, the interest rate meeting in June is to guide rate hike expectations ahead of schedule, and to \"keep silent\" about Taper, which the market is most concerned about.</p><p>The point is, what is the intention of the Fed in doing so?</p><p>After the interest rate meeting, the market followed a combination of a sharp rise in the US dollar and a decline in the 10-year U.S. bond yield. This trend combination is very confusing.</p><p>Let's first guess why the Fed kept silent about Taper.</p><p>In the first quarter, because the market formed optimistic expectations that the U.S. economy would recover rapidly after effective vaccination, the market's expectations for inflation were very high at that time, so the 10-year U.S. bond yield rose very quickly in the first quarter. In a few trading days, the yield rose from less than 1% to a high of 1.78% at the end of March.</p><p>However, the Federal Reserve believes that market expectations have gone too far, constantly emphasizing that inflation is temporary and does not cater to market expectations. In the second quarter, the Fed's balance sheet expansion also continued. Against the background of huge fiscal deposits, all kinds of short-term interest rates have been pressed to around 0.</p><p><img src=\"https://static.tigerbbs.com/f54f3462ee6ddf13338f6b301b11d78b\" tg-width=\"586\" tg-height=\"403\" referrerpolicy=\"no-referrer\"></p><p>There was a reason why the Fed did this in the second quarter. In the first quarter, although vaccines were being vaccinated rapidly, and the U.S. economy benefited from vaccines, it was indeed recovering rapidly, but both the number of jobs and wage growth were far from reaching pre-epidemic levels.</p><p>Withdrawing from easing means that the finance will decline, but there is still a high degree of uncertainty about whether the economic environment in the first quarter can absorb the labor force returning due to the withdrawal of welfare.</p><p>But by the end of the second quarter, it was obvious that the economy had tended to overheat, and the labor market began to be in short supply. Wages are rising at the same time that the number of job vacancies is rising.</p><p>Recently, the number of job vacancies in the United States has reached 9.29 million, compared with almost 7 million in 2019. The job vacancy rate is as high as 6%, and the average level in 2019 is around 4%.</p><p><img src=\"https://static.tigerbbs.com/f6fb48b1ad455cf8f930a98f6abb2752\" tg-width=\"591\" tg-height=\"349\" referrerpolicy=\"no-referrer\"></p><p>By this time, due to the overheating of the job market, the basis for the withdrawal of unemployment benefits has initially been met. What hinders the employment recovery is no longer the weak economic recovery, but the relief payments that even exceed the wages that many employers can pay, which leads to the slow recovery of the labor market. So starting in June, some states have begun to cancel the weekly unemployment benefit of $300.</p><p>We believe that Taper's \"silence\" and the Fed's goal of \"substantial progress\" in the economy most likely refers to a significant increase in employment data after the withdrawal of unemployment benefits, which can verify that the US economy is completely on the right track..</p><p>This is why this interest rate meeting did not raise the unemployment rate target, and remained at the unemployment level of 4.5% after the continued new jobs were lower than expected, because the Federal Reserve expects that after the withdrawal of unemployment benefits, the labor force will gradually return to the job market..</p><p>In short, only when there is a significant improvement in employment growth can the target conditions of \"substantial progress\" desired by the Fed be achieved. Only then will the Fed seriously consider whether the size of the quantitative easing should be reduced.</p><p>Let's review how inflation in the United States is formed.</p><p>The first is that the money printing machine sends money to residents, which leads consumers to \"buy in buy buy\"; The second is that local production has not been repaired, because the employment force has not returned, logistics costs are rising, and the supply of upstream raw materials is scarce (such as the lack of cores for cars and the lack of wood for building houses); The third is that raw material prices, freight and other costs have risen too fast, and China cannot accept new export orders.</p><p>Against the background of rapid demand expansion and relatively tight supply, we have seen that U.S. inflation has shown the characteristics of \"unlimited rise\". Since the supply simply can't match the expansion speed of demand, the residents can't buy the goods if they want to, and the price can only jump.</p><p>This is very similar to the U.S. real estate market. Existing home sales data have been declining since the beginning of this year, but this is not that demand has weakened, because the selling price of existing home sales is still accelerating, and at the same time, existing home inventories in the United States are being consumed.</p><p><img src=\"https://static.tigerbbs.com/95300d19a8a8ee5d831b8f969ae8b639\" tg-width=\"589\" tg-height=\"302\" referrerpolicy=\"no-referrer\"></p><p>In order to alleviate inflationary pressure, the logic is actually very simple. Either curb demand, such as paying less welfare, or guide employment to return to various positions and start production. As welfare goes down, demand weakens, and production increases, inflationary pressure naturally goes down.</p><p>The key now is whether the subsequent employment can increase, which in turn depends on:</p><p>1、<a href=\"https://laohu8.com/S/QC7.SI\">the whole people</a>After immunization, the intensity of the recovery of the U.S. service industry, if the production and supply of oil prices are relatively stable, the rise and fall of oil prices can be used as a high-frequency proxy indicator for the recovery of the service industry;</p><p>2. Have the small and medium-sized enterprises and supply chains in the United States suffered medium and long-term damage due to the epidemic? If so, the supply chain and production links in the United States cannot absorb much employment, and will not have the effect of repairing production.</p><p>These macroeconomic variables, at least from now on, are still uncertain. Only after unemployment benefits are withdrawn can the answer gradually become clear whether employment can increase.</p><p>Therefore, before employment is increased to fill the gap, the Federal Reserve will not be busy mentioning Taper, and it will not withdraw so quickly from providing benefits to residents. According to data from the U.S. Department of Labor, 70% of unemployment benefits will not be withdrawn until the end of the third quarter of this year.</p><p>If the United States can neither curb demand nor expand production scale in the short term, then there is only one way to alleviate inflation, reducing upstream costs, devaluing the exchange rate of producing countries, and replenishing retail inventories by expanding imports to producing countries.</p><p>That's why the Federal Reserve dare not mention Taper, because there is still some uncertainty about whether the job market can be repaired, but the Federal Reserve is willing to advance the market's rate hike expectations and pull up the US dollar, because this can not only devalue the exchange rate of producing countries and expand imports, but also suppress the price of upstream bulk goods, give some production profits to domestic and producing countries, and facilitate the reconstruction of retail inventory.</p><p><b>4. Market meaning</b></p><p>At this point in the story, we think the logic of the follow-up market is very clear.</p><p>At least in the short term, there is no need to pay too much attention to whether the Fed will Taper, because this will only happen after the confirmation of the employment gap repair, and then it will become the focus of market pricing.</p><p>The inflation or stagflation that everyone is hotly speculating about now is essentially the result of a sharp mismatch between supply and demand. When the elasticity of supply is weak to a certain extent, inflation appears in the form of \"unlimited rise\".</p><p>Therefore, the main contradiction in the global economy is no longer to continue to issue money to increase aggregate demand and keep prices going up, but to repair the fragile supply chain and ease inflation expectations through supply repair.</p><p>In other words, behind market pricing deflation is not necessarily the weakening of pricing economic demand, but more likely the short-term repair of pricing supply chain bottlenecks.</p><p>If the United States cannot rebuild its own inventory through the rebalancing of demand and production in the short term, solving the problem of supply chain bottlenecks needs to be solved by expanding imports.</p><p>As commodity prices rise, the cost of the production supply chain rises too fast to receive orders. From this perspective, suppressing the prices of upstream commodities will become the consensus of China and the United States at this stage.</p><p>At present, the focus of the wrestling between the two countries will not be \"pepper noodles\", but may be concentrated in the field of scientific and technological innovation that will form a \"technological generation gap\".</p><p>Therefore, it is best not to expect a unilateral rise in commodity prices at the moment. If commodity prices continue to rise unilaterally, there is a high probability that they will suffer losses.</p><p>In fact, the support for commodity price increases is not entirely due to how strong the current demand is. The expectation that demand exceeds supply plays a big role.</p><p>The low inventory of many commodities is not necessarily caused by the current strong demand and insufficient supply, but because there is an expectation that future demand will be far greater than supply, leading to downstream panic hoarding, superimposed traders' inventory hoarding, and rising prices leading to inventory. Implicit, and the hidden inventory further drives price increases.</p><p>Once the expectation of a unilateral price increase is gone, all the hidden inventory will run out.</p><p>If the United States needs to alleviate the contradiction between insufficient inventory of consumer goods through imports and RMB exchange rate depreciation, it means that there is no big problem for China's exports to remain high in the third quarter.</p><p>This round of domestic pressure on real estate and infrastructure, whether it is industrial production or manufacturing investment, is basically driven by exports. As long as exports can remain high, it means that the economic fundamentals in the third quarter are at least not weak.</p><p>As long as there are fundamentals, the risk appetite of stocks can be guaranteed, and if the upstream price increase can really be controlled, the profit margin of the middle and lower reaches will also come out.

The real interest rate is equal to the nominal interest rate minus inflation expectations. When the nominal interest rate falls, gold continues to fall, and the price of gold has always had an inverse relationship with the real interest rate of the US Treasury Bond</b>That is to say, the real interest rate actually rises when the nominal interest rate falls, which can only show that the expectation of deflation is indeed relatively strong;</p><p><b>4. Expectations for a unilateral rise in commodities seem to no longer exist</b>, taking copper as an example, copper inventories on the London Metal Exchange increased by 24,925 tons, a surge of 17%. After a circle of research, it is said that it is because the supply and demand of copper itself are not so good. The reason why copper prices are strong depends largely on loose liquidity support. Under the expectation of price increases, the industrial chain buys up but not down, and inventories are all hidden, but now the Fed's rate hike expectations have advanced ahead of schedule, and the State Reserve has also sold inventories directly to downstream companies. When the price increase expectations are gone, the hidden inventories of hoarding goods are directly explicit, and the price increase expectations have been shaken.</p><p><b>5. Judging from the recent performance of the U.S. stock market, the market style preferences of U.S. stocks have also undergone significant changes, with the Nasdaq significantly outperforming the Dow</b>, the performance of growth is significantly stronger than cycle and value.</p><p>So, the question is, what happened to make market expectations change so quickly?</p><p>To answer this question, let's briefly analyze how inflation came about.</p><p><b>1. The origin of inflation</b></p><p>There is an essential difference between this round of quantitative easing in the United States and the 2008 financial crisis.</p><p>This time, the United States directly distributed the bills released by the Federal Reserve to residents through fiscal stimulus, while the quantitative easing of the 2008 financial crisis gave banknotes to financial institutions to help them deal with bad debts and illiquid assets.</p><p>Giving banknotes to residents can directly create aggregate demand, while giving banknotes to financial institutions can only create aggregate demand after the entity has financing needs.</p><p>Since the demand stimulation mode of helicopter money is divorced from the traditional historical experience, the speed of production adjustment is slower than the speed of demand expansion, which leads to supply chain bottlenecks and shortage of commodities at the production end.</p><p>Looking at the data of the US inventory-to-sales ratio can illustrate some problems. The seasonally adjusted inventory-to-sales ratio of retailers is the lowest, only 1.07, and the inventory of wholesalers is also relatively low, at 1.22. However, the inventory-to-sales ratio of manufacturers is as high as 1.48, which is still at a high level.</p><p><img src=\"https://static.tigerbbs.com/48ebb5dc27d1a4d9b56b06e650782960\" tg-width=\"590\" tg-height=\"375\" referrerpolicy=\"no-referrer\"></p><p>What does that mean?</p><p>This shows that after the United States issued welfare benefits, the American people's consumer demand for buy buy was too strong, resulting in retailers being bought out of stock. However, because the labor force is still receiving unemployment benefits, they are unwilling to come back to work, and those who come back to work are also Mainly in the service industry, not the manufacturing industry, coupled with expensive raw materials and tight transportation capacity, production has not recovered much.</p><p>The single-month retail sales data in the United States in May was US $620.2 billion, while the single-month retail sales data in the United States in 2019 was just over US $500 billion. Looking at the industrial production index, it was less than 100 in May, but it was around 102 in 2019.</p><p>In other words, consumption is far above pre-epidemic, but production has not yet returned to pre-epidemic.</p><p><img src=\"https://static.tigerbbs.com/acd06a9419c601db0a7cd0d4b4b66049\" tg-width=\"590\" tg-height=\"375\" referrerpolicy=\"no-referrer\"></p><p>Originally, import suppliers in the United States had more choices. For example, by attacking China's textile industry and pushing up upstream costs, China's industrial chain was forced to move out to places with lower labor costs (India, Southeast Asia). Since consumer demand is good and production is insufficient, how should the gap between supply and demand be met? We can only rely on imports.</p><p>Unexpectedly, the epidemic in India in April disrupted this plan. The epidemic not only appeared in India, but also quickly spread to Southeast Asian countries, Taiwan and Japan. These places are mostly production bases in the world. As a result, China's industrial chain not only did not move out, but instead further concentrated production resources domestically. FDI has recently It is accelerating the inflow into the country.</p><p><img src=\"https://static.tigerbbs.com/453c45b93dd234e782b6886c74a10046\" tg-width=\"589\" tg-height=\"299\" referrerpolicy=\"no-referrer\"></p><p>Since the gap in retail inventory in the United States is rigid, and countries and regions with production capacity have also been shut down due to the new round of epidemic, the gap in consumption and inventory in the United States can basically only be balanced by China's imports.</p><p><img src=\"https://static.tigerbbs.com/d0f6894c423cdb48c2a83c6b2eb33a26\" tg-width=\"588\" tg-height=\"321\" referrerpolicy=\"no-referrer\"></p><p><b>2. Unmovable orders</b></p><p>Now come back and look at the domestic.</p><p>Since China took the lead in controlling the epidemic, subsidized enterprises through credit during the epidemic, and maintained enterprises and production capacity. Therefore, from last year to now, China has been the backbone of stabilizing global inflation. The global supply system is highly dependent on China's production. Shipping costs have increased by more than 4-5 times compared with before the epidemic, and individual stocks related to shipping have also increased several times.</p><p><img src=\"https://static.tigerbbs.com/c2d563c458f06a2b983ad41fdf8636d9\" tg-width=\"588\" tg-height=\"295\" referrerpolicy=\"no-referrer\"></p><p>But looking at the current economic data, the new PMI export orders in May were only 48.3%, which was below the boom-and-dry line. Compared with the previous value of 50.4%, there was a more obvious downward trend. The export growth rate in May was 27.9%, which was not as good as the previous value of 32.3%. Now the market has begun to talk more about the peak of external demand.</p><p>From a logical and factual point of view, companies should not be short of orders, because overseas companies can only rely on China's production capacity at present.</p><p>We tend to think that the decline in new export orders is not because enterprises have no orders, but because enterprises dare not take orders easily.</p><p>Why are enterprises afraid to take orders? The main reason is that upstream commodities are sold too fast, and you lose money when you take orders.</p><p>There are three main reasons for the rapid rise in upstream commodity prices:</p><p>1. The demand of the United States can be printed by printing money. Most non-ferrous metals are priced in US dollars. The downward trend of the US dollar and the expansion of demand itself are good for upstream commodities.</p><p>2. Upstream supply cannot be opened, and some of them are unable to resume work due to the lack of vaccines in emerging markets. The spread of the epidemic in India has exacerbated this trend. For example, the semiconductor supply chain is tight, and the supply of scrap copper and some rare minerals has been disturbed; Some are because trade unions are strong; Others feel that demand is not sustainable. Good short-term demand is only printed by the United States and is not sustainable. Now it will be a matter of three years from the expansion of production capacity to the release of output, but if there is no such good demand in the future, You will lose money, so it is better to take advantage of the current price increase to maintain the oligopoly and earn enough cash flow now.</p><p>3. For domestic commodities with pricing power, due to the \"double carbon\" goal, safe production and other demands, the market is expected to reduce production, resulting in hidden inventories, and the downstream will also expect that supply will be in short supply in the future, so they can only panic stocking up at the moment, which intensifies expectations for upstream price increases.</p><p>From the data point of view, the PPI in May was as high as 9% year-on-year, while the CPI was only 1.3% year-on-year. Both the PMI raw material price minus the price of finished products and the PPI raw material price minus the PPI processing price hit a record high year-on-year, which shows that the downstream production and manufacturing links are constantly enduring upstream inflation.</p><p><img src=\"https://static.tigerbbs.com/bf605a70afe88045b7636a1a9c9e0b19\" tg-width=\"589\" tg-height=\"323\" referrerpolicy=\"no-referrer\"></p><p>But everything must have a degree. When the contradiction of the upstream rise accumulates to a certain extent, the company will \"increase income but not increase profits\" and \"thankless\" for a long time, so naturally it will not dare to take orders, because the more orders it takes, the more money it will lose.</p><p><img src=\"https://static.tigerbbs.com/3e11053c2e74d92908dd4a04aa0cfcda\" tg-width=\"587\" tg-height=\"297\" referrerpolicy=\"no-referrer\"></p><p><b>3. The mysterious interest rate meeting</b></p><p>The most interesting thing about the June interest rate meeting is that Taper, which the market is paying attention to, basically didn't mention much, and the expression was very vague. It only said that the premise of opening Taper is to achieve the goal of \"substantial progress\" in the economy, and the standard of \"substantial progress\" It is determined by the Federal Reserve.</p><p>However, the most surprising thing about the June interest rate meeting was that rate hike's expectations were advanced. The number of members who believe that the rate hike should rise from 4 to 7 in 2022, and the number of members who should rate hike in 2023 will rise from 7 to 13.</p><p>On the whole, the interest rate meeting in June is to guide rate hike expectations ahead of schedule, and to \"keep silent\" about Taper, which the market is most concerned about.</p><p>The point is, what is the intention of the Fed in doing so?</p><p>After the interest rate meeting, the market followed a combination of a sharp rise in the US dollar and a decline in the 10-year U.S. bond yield. This trend combination is very confusing.</p><p>Let's first guess why the Fed kept silent about Taper.</p><p>In the first quarter, because the market formed optimistic expectations that the U.S. economy would recover rapidly after effective vaccination, the market's expectations for inflation were very high at that time, so the 10-year U.S. bond yield rose very quickly in the first quarter. In a few trading days, the yield rose from less than 1% to a high of 1.78% at the end of March.</p><p>However, the Federal Reserve believes that market expectations have gone too far, constantly emphasizing that inflation is temporary and does not cater to market expectations. In the second quarter, the Fed's balance sheet expansion also continued. Against the background of huge fiscal deposits, all kinds of short-term interest rates have been pressed to around 0.</p><p><img src=\"https://static.tigerbbs.com/f54f3462ee6ddf13338f6b301b11d78b\" tg-width=\"586\" tg-height=\"403\" referrerpolicy=\"no-referrer\"></p><p>There was a reason why the Fed did this in the second quarter. In the first quarter, although vaccines were being vaccinated rapidly, and the U.S. economy benefited from vaccines, it was indeed recovering rapidly, but both the number of jobs and wage growth were far from reaching pre-epidemic levels.</p><p>Withdrawing from easing means that the finance will decline, but there is still a high degree of uncertainty about whether the economic environment in the first quarter can absorb the labor force returning due to the withdrawal of welfare.</p><p>But by the end of the second quarter, it was obvious that the economy had tended to overheat, and the labor market began to be in short supply. Wages are rising at the same time that the number of job vacancies is rising.</p><p>Recently, the number of job vacancies in the United States has reached 9.29 million, compared with almost 7 million in 2019. The job vacancy rate is as high as 6%, and the average level in 2019 is around 4%.</p><p><img src=\"https://static.tigerbbs.com/f6fb48b1ad455cf8f930a98f6abb2752\" tg-width=\"591\" tg-height=\"349\" referrerpolicy=\"no-referrer\"></p><p>By this time, due to the overheating of the job market, the basis for the withdrawal of unemployment benefits has initially been met. What hinders the employment recovery is no longer the weak economic recovery, but the relief payments that even exceed the wages that many employers can pay, which leads to the slow recovery of the labor market. So starting in June, some states have begun to cancel the weekly unemployment benefit of $300.</p><p>We believe that Taper's \"silence\" and the Fed's goal of \"substantial progress\" in the economy most likely refers to a significant increase in employment data after the withdrawal of unemployment benefits, which can verify that the US economy is completely on the right track..</p><p>This is why this interest rate meeting did not raise the unemployment rate target, and remained at the unemployment level of 4.5% after the continued new jobs were lower than expected, because the Federal Reserve expects that after the withdrawal of unemployment benefits, the labor force will gradually return to the job market..</p><p>In short, only when there is a significant improvement in employment growth can the target conditions of \"substantial progress\" desired by the Fed be achieved. Only then will the Fed seriously consider whether the size of the quantitative easing should be reduced.</p><p>Let's review how inflation in the United States is formed.</p><p>The first is that the money printing machine sends money to residents, which leads consumers to \"buy in buy buy\"; The second is that local production has not been repaired, because the employment force has not returned, logistics costs are rising, and the supply of upstream raw materials is scarce (such as the lack of cores for cars and the lack of wood for building houses); The third is that raw material prices, freight and other costs have risen too fast, and China cannot accept new export orders.</p><p>Against the background of rapid demand expansion and relatively tight supply, we have seen that U.S. inflation has shown the characteristics of \"unlimited rise\". Since the supply simply can't match the expansion speed of demand, the residents can't buy the goods if they want to, and the price can only jump.</p><p>This is very similar to the U.S. real estate market. Existing home sales data have been declining since the beginning of this year, but this is not that demand has weakened, because the selling price of existing home sales is still accelerating, and at the same time, existing home inventories in the United States are being consumed.</p><p><img src=\"https://static.tigerbbs.com/95300d19a8a8ee5d831b8f969ae8b639\" tg-width=\"589\" tg-height=\"302\" referrerpolicy=\"no-referrer\"></p><p>In order to alleviate inflationary pressure, the logic is actually very simple.

As long as exports can remain high, it means that the economic fundamentals in the third quarter are at least not weak.</p><p>As long as there are fundamentals, the risk appetite of stocks can be guaranteed, and if the upstream price increase can really be controlled, the profit margin of the middle and lower reaches will also come out. You can pay attention to the opportunities in the growth sector, especially the underlying core components and independent and controllable policy premium of materials.</p><p>Of course, the

FDI近期是加速往国内流入的。\n\n由于美国的零售品库存的缺口是刚性的，拥有生产能力的国家和地区也因新一轮疫情停摆，美国消费和库存的缺口基本上只能靠中国的进口来平衡了。\n\n二、接不动的订单\n现在回来看看国内。\n由于中国率先控制了疫情，疫情期间通过信贷补贴了企业，保住了企业和生产能力，所以从去年到现在，中国一直都是稳定全球通胀的中坚力量，全球的供应体系高度依赖于中国的生产，海运费用比疫情前涨了4-5倍都不止，和海运相关的个股涨幅也有好几倍。\n\n但看现在的经济数据，5月PMI新出口订单只有48.3%，到了枯荣线的下面，相比前值50.4%，有较为明显的下行。5月的出口增速为27.9%，也不如前值的32.3%，现在市场关于外需的见顶讨论开始多了起来。\n从逻辑和事实上来讲，企业应该是不会缺订单的，因为当下海外只能依赖中国的产能。\n我们倾向于认为出口新订单的下降不是因为企业没有订单，而是企业不敢轻易接订单了。\n企业为什么不敢接订单呢？主要原因是上游大宗商品上得太快了，接单就亏钱。\n上游大宗商品价格涨得快的原因主要有三个：\n1、美国的需求可以靠印钞票印出来，大多数有色金属是美元定价，美元下行和需求扩张本身就利好上游大宗商品。\n2、上游供给打不开，有的是因为新兴市场缺少疫苗导致无法复工，印度疫情扩散加剧了这一趋势，比如半导体供应链紧张、废铜还有一些稀有矿的供给都受到了扰动；有的是因为工会强势；还有的是觉得需求没有持续性，短期需求好只是美国印出来的，没有可持续性，现在扩产能到产出释放都是未来三年以后的事了，但未来如果没有这么好的需求，就会赔钱，所以不如趁现在价格涨维持寡头垄断，当下赚足现金流就好。\n3、国内有定价权的大宗商品，因“双碳”目标、安全生产等诉求，市场有减产预期，导致库存隐性化，而且下游也会预期未来供应会紧缺，只能当下恐慌性备货，使得上游价格上涨预期加剧。\n从数据来看，5月PPI同比高达9%，而CPI同比仅为1.3%，无论是PMI原材料价格减去产成品价格还是PPI原材料价格同比减去PPI加工价格同比都创下了历史新高，这说明下游生产制造环节在不断忍受着上游的通胀。\n\n但凡事都得有个度，当上游上涨的矛盾积累到了一定程度后，企业长期“增收不增利”、“吃力不讨好”，自然就不敢接订单了，因为订单接得越多，反而会越赔钱。\n\n三、谜一样的议息会议\n6月议息会议最有趣的一点就是市场关注的Taper基本上没怎么提，表述很模糊，只说Taper开启的前提是达到经济取得“实质性进展”的目标，而“实质性进展”的标准是由美联储决定的。\n但6月议息会议最让市场意外的一点是加息预期提前了，认为2022年应当加息的成员从4人上升到了7人，2023年应当加息的成员从7人上升到了13人。\n综合来看，6月议息会议是引导加息预期提前，并且对市场最关注的Taper“闭口不提”。\n关键是，美联储这么做的意图是什么？\n议息会议后，市场走的是美元大幅上涨而10年美债收益率下行的组合，这种走势组合让人很疑惑。\n先来猜测一下，美联储为什么对Taper闭口不提。\n一季度的时候，因为市场形成了疫苗有效接种后美国经济会快速复苏的乐观预期，当时市场对通胀的预期很靠前，所以一季度10年期美债收益率上升的速度非常快，没几个交易日就从不到1%的收益率上行到了3月末1.78%的高点。\n但美联储认为市场预期走得太前了，不断在强调通胀是暂时的，没有去迎合市场预期。二季度美联储的扩表也在继续，在财政存款巨量投放的背景下，各类短端利率都压到了0附近。\n\n二季度美联储这么做也是有原因的。一季度的时候，疫苗虽然在快速接种，美国经济受益于疫苗，确实是在快速修复，但无论是就业数量还是薪资增速，都远没有达到疫情前的水平。\n退出宽松就意味着财政要退坡，但一季度的经济环境是否能吸纳因福利退出而回流的劳动力大军，还是有很高的不确定性的。\n但到了二季度末，很明显可以看到经济已经有了过热的倾向，劳动力市场开始供不应求。工资上涨的同时职位空缺人数也在不断上升。\n近期美国就业职位空缺人数已高达929万人，而2019年差不多就700万人左右，职位空缺率高达6%，而2019年的平均水平也就在4%左右的水平。\n\n到了这个时候，由于就业市场过热，已初步具备失业救济退出的基础。阻碍就业复苏的不再是经济复苏不给力，而是救济金甚至超过了许多雇主可以支付的工资，才导致劳动力市场复苏缓慢。所以从6月开始，已经有部分州开始取消每周300美元的失业救济金。\n我们认为Taper“闭口不提”，美联储要的经济“实质性进展”的目标，大概率指的是失业救济退出以后，就业数据要出现明显的新增，这才能验证美国经济已经彻底走上正轨。\n这也是为什么此次议息会议并没有上调失业率目标，在持续的新增就业低于预期之后还维持在4.5%的失业水平，因为美联储预期失业救济退出之后，劳动力就会逐步回归到就业市场。\n简而言之，只有等到就业新增真的有明显改善后，才能达到美联储要的“实质性进展”的目标条件。也只有等到那个时候，美联储才会认真考虑量化宽松规模是不是要缩减。\n下面我们再来回顾一下美国的通胀是怎么形成的。\n第一个是印钞机给居民发钱导致消费者“买买买”；第二个是本土生产没有修复，因为就业大军没有回归的、物流成本上升和上游原材料供给稀缺（比如汽车缺芯、盖房子缺木材）；第三个是原材料价格、运费等各类成本涨得太快，中国也接不动出口新订单。\n在需求扩张较快和供应相对紧缺的背景下，我们看到美国通胀呈现出了“无量上涨”的特征。由于供给根本匹配不上需求的扩张的速度，居民部门想买都买不到货，价格就只能跳涨了。\n这跟美国房地产市场很像，成屋销售数据从今年年初就开始下降了，但这并不是需求减弱了，因为成屋销售的售价还在加速上行，与此同时，美国成屋库存在被消耗。\n\n要想缓解通胀压力，其实逻辑也很简单，要么抑制需求，比如少发点福利，要么引导就业回归到各个岗位上去，把生产弄起来。福利下去了，需求弱了，而生产变多了，通胀压力自然就下去了。\n现在的关键就是后续就业新增能不能上去，这又取决于：\n1、全民免疫后，美国服务业复苏的强度，如果油价生产供应比较稳定，油价涨跌可以作为服务业修复高频代理指标；\n2、美国的中小企业和供应链是不是因为疫情受到了中长期损害，如果是的话，美国的供应链和生产环节吸纳不了多少就业，也就起不到修复生产的效果。\n这些宏观经济变量，至少从现在来看，还是有不确定性的，要等到失业救济退出后，就业能否放量，答案才能逐渐明晰。\n所以，在就业放量补缺口前，美联储是不会忙着提Taper的，给居民部门发福利也不会那么快退出。从美国劳工部的数据来看，70%的失业救济到了今年三季度末才会陆续退出。\n如果美国短期既做不到抑制需求，也无法扩大生产规模，那缓解通胀就只有一个办法，降上游成本，让生产国的汇率贬值，通过扩大对生产国的进口来补充零售的库存。\n这就是为什么美联储不敢提Taper,因为就业市场能不能修复还有一定的不确定，但美联储愿意把市场的加息预期提前，把美元拉上去，因为这样既可以让生产国的汇率贬值进而扩大进口，也可以打压一下上游大宗的价格，给本国和生产国一些生产的利润，方便重建零售库存。\n四、市场含义\n故事讲到这里，我们认为后续市场的逻辑就非常清晰了。\n至少在短期，没有过于关注美联储是否会Taper的必要，因为这个需要就业缺口修复的确认后才会发生，然后才会成为市场定价的焦点。\n现在大家都热炒的通胀或滞胀，本质上都是供需急剧错配的结果，当供给的弹性弱到一定程度以后，通胀是以“无量上涨”的形式出现的。\n所以，现在全球经济的主要矛盾不再是要继续发钞票去拉高总需求，让物价继续往上走，而是修复脆弱的供应链，通过供给修复来缓和通胀的预期。\n换言之，市场定价通缩的背后不一定是在定价经济需求的走弱，更有可能是在定价供应链瓶颈的短期修复。\n如果美国短期无法通过需求生产的再平衡重建自身的库存，解决供应链瓶颈的问题就需要通过扩大进口来解决。\n由于大宗商品价格上涨使得生产供应链的成本攀升太快，接不动订单，从这个角度来看，打压上游大宗商品的价格在现阶段会成为中美两国的共识。\n两国角力的重点，在当下也不会是“撒胡椒面”式的，而是有可能集中在会形成“技术代差”的科技创新领域。\n所以，当下最好别有大宗商品价格单边上涨的预期，赌大宗商品价格继续单边上涨大概率是会吃亏的。\n其实大宗商品涨价的支撑也不完全是因为当前的需求有多强，求大于供的预期起到了很大的作用。\n很多大宗商品的低库存并一定是因为当下需求旺盛而供应不足导致的，而是因为存在未来需求会远大于供给的预期，导致下游恐慌性囤货，叠加贸易商库存囤积，价格上涨导致库存隐性化，而库存隐性化又进一步驱动了价格上涨。\n一旦价格单边上涨的预期没了，隐藏的库存就都跑出来了。\n如果说美国需要通过进口和人民币汇率贬值来缓解消费品库存不足的矛盾，这意味着中国三季度出口维持高位的问题不大。\n这一轮国内压着房地产和基建，无论是工业生产还是制造业投资，基本上是靠出口驱动的，只要出口还能维持高位，那就意味着三季度经济基本面至少是不弱的。\n只要有基本面搭台，股票的风险偏好就能有保障，而且上游价格涨幅如果真能控制，中下游的盈利空间也就出来了，可以关注成长板块的机会，尤其要关注底层核心零部件和材料自主可控的政策溢价。\n当然，“通胀交易”可以暂歇了。","news_type":1,"symbols_score_info":{"161125":0.9,"513500":0.9,"TQQQ":0.9,"DJX":0.9,"ZFmain":0.9,"SQQQ":0.9,"ESmain":0.9,"PSQ":0.9,".SPX":0.9,"UPRO":0.9,"ZNmain":0.9,"ZBmain":0.9,"ZTmain":0.9,"DXD":0.9,"OEX":0.9,"QID":0.9,"SSO":0.9,"UBmain":0.9,".IXIC":0.9,"SPXU":0.9,"OEF":0.9,"TNmain":0.9,"MNQmain":0.9,"SDS":0.9,"DDM":0.9,"SDOW":0.9,"SPY":0.9,"SH":0.9,"DOG":0.9,"QLD":0.9,"QQQ":0.9,"IVV":0.9,"NQmain":0.9,"UDOW":0.9}},"isVote":1,"tweetType":1,"viewCount":1768,"authorTweetTopStatus":1,"verified":2,"comments":[],"imageCount":0,"langContent":"EN","totalScore":0}],"hots":[{"id":891905053,"gmtCreate":1628313286272,"gmtModify":1703504978278,"author":{"id":"3568614602734225","authorId":"3568614602734225","name":"洞幽烛远","avatar":"https://static.tigerbbs.com/0e72968722642d797ced5fcb63f2fec1","crmLevel":11,"crmLevelSwitch":0,"followedFlag":false,"authorIdStr":"3568614602734225","idStr":"3568614602734225"},"themes":[],"htmlText":"Look","listText":"Look","text":"Look","images":[],"top":1,"highlighted":1,"essential":1,"paper":1,"likeSize":2,"commentSize":0,"repostSize":0,"link":"https://t

In addition, Hangzhou also stipulates that the houses with low lottery winning rate of new houses should be sorted according to the number of months of social security payment, which aims to prevent too many buyers from getting together to snap up.</p><p><img src=\"https://static.tigerbbs.com/98d5061e381a588a0b72f0c700d4c53c\" tg-width=\"1080\" tg-height=\"699\" referrerpolicy=\"no-referrer\"></p><p>At the same time,<b>Chengdu includes donated housing in the total number of donee family housing units to review house purchase qualifications</b>。 In other words, the loophole of avoiding purchase restriction through gifts has been completely blocked.</p><p><img src=\"https://static.tigerbbs.com/251b49b66315bacb1edb0024546db0d8\" tg-width=\"1080\" tg-height=\"717\" referrerpolicy=\"no-referrer\"></p><p><b>However, Beijing's regulations are more targeted, directly focusing on the regulation and control to crack down on the qualification of purchasing houses through \"fake divorce\"</b>。 The new regulations clarify that if a husband and wife divorce, and the number of housing units owned by the original family before divorce does not meet the purchase restriction policy of commercial housing, neither party may purchase commercial housing within 3 years from the date of divorce. In recent years, in some hot cities, due to the continuous tightening of the purchase restriction policy, some people have racked their brains in order to obtain the qualification to buy houses. In order to avoid the purchase restriction, get the qualification to buy a house again, and enjoy the low down payment and low loan interest rate for buying the first house, some families even choose to divorce and buy a house again. Beijing's new regulations make it more difficult to buy a house through \"fake divorce\", which is conducive to plugging the loopholes of \"fake divorce\" real estate speculation.</p><p><img src=\"https://static.tigerbbs.com/54b84384c49789d1fc5e6ac49f40f066\" tg-width=\"1080\" tg-height=\"497\" referrerpolicy=\"no-referrer\"></p><p>Local control measures are still being intensively introduced, constantly \"patching\" and \"plugging loopholes\". The reason is that some cities still face the situation of excessive growth of house prices and land prices and unstable market expectations.<b>The constant regulation measures are a continued deterrent to speculators who still have illusions about the rapid rise in housing prices</b>。</p><p>If the false fire is not extinguished, the regulation of the property market needs to keep high pressure, and more importantly, long-term policies that are continuously and stably implemented are needed, so that buyers can have more stable expectations for the trend of house prices and the timing of house purchase.<b>Intensive regulation measures show that local governments, which are responsible for real estate regulation, are increasing their initiative and enthusiasm in implementing property market regulation</b>。 Since the beginning of this year, the Ministry of Housing and Urban-Rural Development has interviewed local governments many times and included these cities in the list of key cities for real estate market monitoring. For local governments, the positioning of \"housing is for living, not for speculation\" and \"not using real estate as a short-term means to stimulate the economy\" should always be adhered to.</p><p>The meeting of the Political Bureau of the Central Committee held a few days ago emphasized that it is necessary to adhere to the positioning that houses are for living, not for speculation, stabilize land prices, housing prices and expectations, and promote the stable and healthy development of the real estate market. Since my country proposed the establishment of a long-term mechanism for real estate, remarkable results have been achieved in stabilizing land prices, housing prices, and expectations, indicating that the measures taken are in line with the laws of market development and are accurate and effective. When individual cities show signs of overheating, it is necessary to decisively strengthen the regulation and supervision of the real estate market. Fortunately,<b>The \"tools\" for regulating the real estate market are constantly enriching, and a series of measures such as land, finance, administrative measures, market rectification, fiscal and taxation are forming a strong synergy</b>。 It is believed that with the establishment and improvement of the long-term mechanism of real estate, the real estate market will usher in a good situation of healthier development.</p>\n<div class=\"bt-text\">\n\n\n<p> source：<a href=\"https://www.gelonghui.com/p/479661\">经济日报</a></p>\n\n\n</div>\n</article>\n</div>\n</body>\n</html>\n","type":0,"thumbnail":"https://static.tigerbbs.com/c3c5822c22b6cfd1d0ae2625b7bc085e","relate_stocks":{"09979":"绿城管理控股"},"source_url":"https://www.gelonghui.com/p/479661","is_english":false,"share_image_url":"https://static.laohu8.com/e9f99090a1c2ed51c021029395664489","article_id":"1109676905","content_text":"各地调控措施还在密集出台，不断“打补丁”“堵漏洞”。其原因在于一些城市依然面临房价和地价增长过快、市场预期不稳的状况。这对幻想房价过快上涨的炒房客们是持续的威慑。\n\n楼市调控持续加码。仅8月5日一天，就有杭州、北京、成都三城推出房地产调控新规。\n杭州进一步抬高了购房门槛。新举措明确，取得杭州户口未满5年，需缴纳两年社保，可在限购区域购买一套住房；“非户籍+4年社保”的要求让非杭州户籍购房者买房难度加大。杭州调控新规抬高购房门槛目的在于打击短期投资客。此外，杭州还规定新房摇号中签率低的房源，按照社保缴纳月数依次排序，此举旨在避免过多购房者扎堆抢购。\n\n与此同时，成都将赠与住房计入受赠人家庭住房总套数审核购房资格。也就是说，通过赠与方式规避限购的漏洞被彻底堵住了。\n\n而北京的规定更具针对性，直接将调控重点放在打击通过“假离婚”获取购房资格上。新规明确，夫妻离异的，原家庭在离异前拥有住房套数不符合商品住房限购政策规定的，自离异之日起3年内，任何一方均不得购买商品住房。近年来，在一些热点城市，由于限购政策不断收紧，一些人为了获取购房资格，可谓绞尽脑汁。为避开限购，获得再购房的资格，以及享受购买首套住房的低首付款和低贷款利率，一些家庭甚至选择离婚再购房。北京新规让通过“假离婚”进行购房的难度加大，有利于封堵“假离婚”炒房漏洞。\n\n各地调控措施还在密集出台，不断“打补丁”“堵漏洞”。其原因在于一些城市依然面临房价和地价增长过快、市场预期不稳的状况。不断出台的调控措施对于那些依然对房价过快上涨抱有幻想的炒房客们是持续的威慑。\n虚火不灭，楼市调控就需保持高压，更需持续且稳定执行的长效政策，以便购房者对房价走势、购房时点有更稳定的预期。密集出台的调控措施表明，对房地产调控负有主体责任的地方政府，实施楼市调控的主动性和积极性都在增加。今年以来，住房和城乡建设部已多次约谈地方政府，并将这些城市纳入房地产市场监测重点城市名单。对于地方政府而言，“房住不炒”及“不将房地产作为短期刺激经济的手段”的定位应始终坚持。\n日前召开的中央政治局会议强调，要坚持房子是用来住的、不是用来炒的定位，稳地价、稳房价、稳预期，促进房地产市场平稳健康发展。我国提出建立房地产长效机制以来，稳地价、稳房价、稳预期取得明显成效，表明采取的措施符合市场发展规律，精准有效。当个别城市出现过热苗头，须果断加大房地产市场调控力度和监管力度。可喜的是，房地产市场调控的“工具”在不断丰富，土地、金融、行政措施、市场整顿、财税等一系列措施，正在形成强大合力。相信随着房地产长效机制建立和完善，房地产市场将迎来更加健康发展的良好局面。","news_type":1,"symbols_score_info":{"09979":0.9}},"isVote":1,"tweetType":1,"viewCount":2151,"authorTweetTopStatus":1,"verified":2,"comments":[],"imageCount":0,"langContent":"EN","totalScore":0},{"id":152958607,"gmtCreate":1625265952809,"gmtModify":1703739508025,"author":{"id":"3568614602734225","authorId":"3568614602734225","name":"洞幽烛远","avatar":"https://static.tigerbbs.com/0e72968722642d797ced5fcb63f2fec1","crmLevel":11,"crmLevelSwitch":0,"followedFlag":false,"authorIdStr":"3568614602734225","idStr":"3568614602734225"},"themes":[],"htmlText":"Ok","listText":"Ok","text":"Ok","images":[],"top":1,"highlighted":1,"essential":1,"paper":1,"likeSize":2,"commentSize":0,"repostSize":0,"link":"https://ttm.financial/post/152958607","repostId":"2148808400","repostType":4,"repost":{"id":"2148808400","kind":"news","pubTimestamp":1625238620,"share":"https://ttm.financial/m/news/2148808400?lang=en_US&edition=fundamental","pubTime":"2021-07-02 23:10","market":"us","language":"zh","title":"From the Tesla recall incident, a glimpse of the true face of OTA car evolution","url":"https://stock-news.laohu8.com/highlight/detail?id=2148808400","media":"脑极体","summary":"特斯拉在科技圈中，是个有话题有热点的黑网红，曝出来的永远都是各种控制系统失控出车祸的新闻，这不最近又闯祸了。近日消息，特斯拉召回部分进口和国产Model 3、国产Model Y电动汽车，共计28552","content":"<p><a href=\"https://laohu8.com/S/TSLA\">Tesla</a>In the science and technology circle, it is a black online celebrity with hot topics. What is exposed is always the news of various control systems getting out of control and causing car accidents, which has caused trouble again recently. According to recent news, Tesla recalled some imported and domestically produced Model 3 and domestically produced Model Y electric vehicles, totaling 285,520 vehicles. The main reason for the recall is that the vehicles have potential safety hazards in the active cruise control system, which can easily cause the driver to turn or be in D gear. Accidentally activating the active cruise function may lead to a sudden increase in vehicle speed, which may lead to vehicle collisions in extreme cases.</p><p>It looks very scary. After all, it is related to car safety. Tesla's large-scale recall is not a way to physically return the car to the factory for rebates, but through the technology of remotely upgrading the OTA of the car, users can complete the online upgrade without going to the store. Can the seemingly serious security hazard be solved just by updating the security package through OTA? This recall method, without the follow-up routine safety test of the car manufacturer, always feels uneasy, and even makes people have doubts about the safety of OTA technology itself. So is the OTA system safe after all? To answer this question, let's start with what an OTA car is.</p><p><b>What exactly is an OTA car?</b></p><p>The full name of OTA is \"Over-The-Air\", which means Over-The-Air download technology (remote upgrade technology), a technology that downloads data packets through wireless networks to update the system and improve terminal functions and services. Our computers and mobile phones also use this OTA technology when updating the system. The purpose of OTA system upgrade is to fix system vulnerabilities, optimize and improve to obtain more functions, performance improvement, or visual effect improvement, and this update is through online detection, version matching, download new code to the local area after networking, and then execute installation, verification and other procedures.</p><p><img src=\"https://static.tigerbbs.com/404652f159ffcb9982e091e353fdade0\" tg-width=\"868\" tg-height=\"538\" referrerpolicy=\"no-referrer\"></p><p>The first application of OTA technology was in the ModeL S launched by Tesla in 2012. The content update scope includes human-computer interaction, autonomous driving, power battery system and other modules. At that time, Tesla could complete key card vulnerabilities through OTA. Improve cruising range, improve maximum speed, improve ride comfort, etc.</p><p>Automotive OTA technology can be divided into SOTA (Software OTA, software over-the-air upgrade) and FOTA (Firmware OTA, firmware over-the-air upgrade) according to the difference of upgraded firmware, that is, vehicle OTA. Among them, SOTA can only update vehicle application layer software, limited to vehicle machine, infotainment and other software, and has almost no hardware scheduling capabilities. It is less difficult for car companies to implement it. Most of the OTA cars often advertised on the market are only with SOTA technology. FOTA upgrades the system layer of the vehicle controller, which affects the vehicle's power system, battery management and other systems. For example, it can update the OS layer software of the underlying systems such as chassis, power, and ADAS.</p><p>The main difference between cars equipped with OTA technology and traditional cars is: in terms of performance, cars equipped with OTA technology have richer on-board functions. Generally speaking, they realize functions from these aspects: they can fix system bugs, update drivers, optimize UI interface, delete problematic apps, upgrade major versions, etc. Most automotive OTAs generally launch online system updates for entertainment systems, navigation, etc.</p><p>Secondly, when the vehicle encounters software failure or needs to be updated, the traditional car needs to drive the car to a 4S shop and use a professional computer to repair it, which takes time and energy. However, the car equipped with OTA technology can complete the vehicle upgrade and repair problems without leaving home, saving costs and time. For example, OTA cars can update the ECU software of the car. ECU is the automobile electronic controller. In layman's terms, it is the brain of the car. When a new car leaves the factory, the power will not be fully exerted, usually leaving some room for improvement. Brushing the ECU is to use some technical means to encode the ECU on the basis of the original engine's ability to bear it to achieve the purpose of increasing horsepower or torque. Traditional cars need to rely on the original technology to brush the ECU, and OTA cars can upgrade this capability online.</p><p>From the above description, it can be seen that the functions and convenience of vehicles equipped with OTA technology are exciting and favorable, but because OTA technology itself involves changes in vehicle physical properties such as ECU changes, battery performance changes, and vehicle software experience functions, among them, some reefs may be touched.</p><p><b>OTA cars are a double-edged sword</b></p><p>Judging from the conservative choice of traditional car companies, there is a reason why people don't accept all these wonderful experiences according to the order, and they are not so keen on carrying them. OTA cars are also a double-edged sword.</p><p><img src=\"https://static.tigerbbs.com/b9e367c30b535b8c2a265e8ccd88751a\" tg-width=\"1000\" tg-height=\"616\" referrerpolicy=\"no-referrer\"></p><p>First of all, because of the mature R&D cycle and stable enterprise structure of traditional automobiles, there are too many newly matched components to realize OTA, and the cost of changing production lines and enterprise structures is too high. These new components need to undergo high-cost tests. After testing, automobile manufacturers will not integrate a bunch of untested \"semi-finished products\" and put them on the market, which will affect the safety of lives and property.</p><p>From the analysis of technical reasons, it is mainly related to the structure of traditional cars. Traditional cars are purely mechanical structures, and the power unit is very complex. The parameters such as fuel injection volume, braking system, shift logic, steering ratio, and suspension style are calibrated, and they need to be debugged and tested by engineers tens of millions of times to the best safe state before they can leave the factory. However, rebuilding OTA becomes unstable for power output and destroys the balanced parameter settings.</p><p>In addition to the security risks of physical hardware devices, OTA technology is at risk of being hacked during the remote upgrade process. In the process of downloading the upgrade package of the car, hackers can use network means to send the virus upgrade package to the vehicle, and then modify the system, remotely control and extort money. If you encounter some extreme weather or unstable environmental network, it will also lead to vulnerabilities in the upgrade package, which will cause the vehicle upgrade to fail.</p><p>We can see that OTA technology needs to go through a lot of security tests in the matching of physical equipment components themselves, as well as in the protocol and design process. No matter which link there is hidden danger in the link coupling between software and hardware devices, it is a matter of life and death for the safety of enterprises and vehicles. The problem cannot be played with. Take this recall of Tesla as an example. For the operation of ACC adaptive cruise control, the conventional design scheme of car companies is to use push-button or independent lever operation to turn on the adaptive cruise function. However, Tesla is prone to misoperation when using the adaptive cruise control function, which is a design logic defect. Tesla's solution is to raise the threshold of activating active cruise and add reminders of its activation and exit to avoid the possible recurrence of accidental touch.</p><p>If the logic setting of a small function is wrong, it will also bring irreparable results. Regarding safety issues, we cannot assume that everyone is cautious and does not have a short-circuit in their brains. If it is not uncommon to pay attention to vehicle-related news recalls, OTA can solve some software faults through upgrades, but whether it will bring new problems will also be an urgent problem to be solved. It can be seen that OTA technology is a double-edged sword for car companies, and it is meaningless to discuss whether it is absolutely safe. The road to intelligence of OTA cars will not be achieved overnight. Some system flaws need time to gradually iteratively optimize. After all, there is no product. It is perfect from the beginning of design.</p><p><img src=\"https://static.tigerbbs.com/e094f51a71e4d181f644eb1da3c657c5\" tg-width=\"1080\" tg-height=\"643\" referrerpolicy=\"no-referrer\"></p><p>At present, the development trend of the entire market is that car companies are gradually embracing OTA technology, and will not give up food because of local restrictions. OTA technology is becoming the standard feature of smart cars, and its technology penetration rate is particularly obvious. Statistics show that 30% of vehicles sold worldwide in 2020 have OTA functions. It will rise to 79% by 2025. According to data released by the Gaogong Intelligent Automobile Research Institute, the OTA installation rate of new cars in the Chinese market has reached 22.42% in 2020, and is expected to increase to 35-40% this year.</p><p>Although many car companies are trying their best to market OTA upgrade technology at the press conference, there are also many people swimming naked. Most car companies still stay at the SOTA upgrade level, that is, the functional upgrade at the entertainment and interaction level. There are only a handful of car companies that can upgrade the whole vehicle OTA. At present, upstarts such as Tesla, Ideal, XPeng, etc. have vehicle OTA capabilities. The OTA upgrade for the whole vehicle is a very significant sign that smart cars are different from traditional cars. From the perspective of the development history of OTA vehicles, the demand for OTA in the automotive industry is gradually developing from the parts level, vehicle level, and enterprise level to the industry ecological level. Traditional car companies such as BMW, Volkswagen, and SAIC-GM are actively reforming and reconstructing their electronic architecture in this major change to realize vehicle OTA.</p><p><b>The road to the future test of OTA cars</b></p><p>Nowadays, most car companies can achieve OTA of car-machine entertainment systems, that is, SOTA, but the real hard nut to crack is the whole vehicle FOTA. Because it involves the electronic architecture, hardware configuration and software self-research capabilities of vehicle manufacturers in new cars. The electronic controller needs to be deeply integrated with the update mechanism of the equipment. In what state the vehicle is flashed and written, and how to ensure the stability and safety of the update process. These implementation difficulties must be considered. For example, there are hundreds of ECUs (automotive electronic control components) of automobile interior components in the architecture of the whole vehicle, and they are connected in different communication networks. The data transmission protocols of each network are different and complicated. The more the upgraded controller considers, the more difficult it is to double the network communication topology protocols. OTA suppliers need to have a clear understanding of the characteristics of each communication line in order to efficiently realize software upgrades.</p><p><img src=\"https://static.tigerbbs.com/5529364f1b506bceb17619a2c75f3112\" tg-width=\"1080\" tg-height=\"600\" referrerpolicy=\"no-referrer\"></p><p>In terms of information security, in the process of OTA data transmission, there are potential risks of being counterfeited, stolen, and attacked. During the communication process, it will be held hostage and tampered with by malicious hackers, which may lead to abnormal vehicle operation, privacy leakage, financial and even life safety is threatened. It is particularly important to ensure the safety upgrade of OTA cars. OTA automobile manufacturers need to build a well-designed identification key technology architecture, and the limitation of verification mechanism and upgrade conditions requires two-way control to ensure an information security system integrating device and cloud.</p><p>The realization of OTA car functions relies on the development of various capabilities such as gateway protocols, network security, and continuous development of computing algorithm technology. Although electronic modules and software technologies develop together and are more and more applied in complete vehicles, the technology is still not mature. At the stage of widespread social recognition, the development of smart cars is long and long, and there is still a lot of room for updates and improvements. The optimization of OTA car functions and service differentiation need to evolve simultaneously. Fortunately, we will witness the surprises brought by OTA cars together.</p>","source":"lsy1577414888172","collect":0,"html":"<!DOCTYPE html>\n<html>\n<head>\n<meta http-equiv=\"Content-Type\" content=\"text/html; charset=utf-8\" />\n<meta name=\"viewport\" content=\"width=device-width,initial-scale=1.0,minimum-scale=1.0,maximum-scale=1.0,user-scalable=no\"/>\n<meta name=\"format-detection\" content=\"telephone=no,email=no,address=no\" />\n<title>From the Tesla recall incident, a glimpse of the true face of OTA car evolution</title>\n<style type=\"text/css\">\na,abbr,acronym,address,applet,article,aside,audio,b,big,blockquote,body,canvas,caption,center,cite,code,dd,del,details,dfn,div,dl,dt,\nem,embed,fieldset,figcaption,figure,footer,form,h1,h2,h3,h4,h5,h6,header,hgroup,html,i,iframe,img,ins,kbd,label,legend,li,mark,menu,nav,\nobject,ol,output,p,pre,q,ruby,s,samp,section,small,span,strike,strong,sub,summary,sup,table,tbody,td,tfoot,th,thead,time,tr,tt,u,ul,var,video{ font:inherit;margin:0;padding:0;vertical-align:baseline;border:0 }\nbody{ font-size:16px; line-height:1.5; color:#999; background:transparent; }\n.wrapper{ overflow:hidden;word-break:break-all;padding:10px; }\nh1,h2{ font-weight:normal; line-height:1.35; margin-bottom:.6em; }\nh3,h4,h5,h6{ line-height:1.35; margin-bottom:1em; }\nh1{ font-size:24px; }\nh2{ font-size:20px; }\nh3{ font-size:18px; }\nh4{ font-size:16px; }\nh5{ font-size:14px; }\nh6{ font-size:12px; }\np,ul,ol,blockquote,dl,table{ margin:1.2em 0; }\nul,ol{ margin-left:2em; }\nul{ list-style:disc; }\nol{ list-style:decimal; }\nli,li p{ margin:10px 0;}\nimg{ max-width:100%;display:block;margin:0 auto 1em; }\nblockquote{ color:#B5B2B1; border-left:3px solid #aaa; padding:1em; }\nstrong,b{font-weight:bold;}\nem,i{font-style:italic;}\ntable{ width:100%;border-collapse:collapse;border-spacing:1px;margin:1em 0;font-size:.9em; }\nth,td{ padding:5px;text-align:left;border:1px solid #aaa; }\nth{ font-weight:bold;background:#5d5d5d; }\n.symbol-link{font-weight:bold;}\n/* header{ border-bottom:1px solid #494756; } */\n.title{ margin:0 0 8px;line-height:1.3;color:#ddd; }\n.meta {color:#5e5c6d;font-size:13px;margin:0 0 .5em; }\na{text-decoration:none; color:#2a4b87;}\n.meta .head { display: inline-block; overflow: hidden}\n.head .h-thumb { width: 30px; height: 30px; margin: 0; padding: 0; border-radius: 50%; float: left;}\n.head .h-content { margin: 0; padding: 0 0 0 9px; float: left;}\n.head .h-name {font-size: 13px; color: #eee; margin: 0;}\n.head .h-time {font-size: 12.5px; color: #7E829C; margin: 0;}\n.small {font-size: 12.5px; display: inline-block; transform: scale(0.9); -webkit-transform: scale(0.9); transform-origin: left; -webkit-transform-origin: left;}\n.smaller {font-size: 12.5px; display: inline-block; transform: scale(0.8); -webkit-transform: scale(0.8); transform-origin: left; -webkit-transform-origin: left;}\n.bt-text {font-size: 12px;margin: 1.5em 0 0 0}\n.bt-text p {margin: 0}\n</style>\n</head>\n<body>\n<div class=\"wrapper\">\n<header>\n<h2 class=\"title\">\nFrom the Tesla recall incident, a glimpse of the true face of OTA car evolution\n</h2>\n<h4 class=\"meta\">\n<p class=\"head\">\n<strong class=\"h-name small\">脑极体</strong><span class=\"h-time small\">2021-07-02 23:10</span>\n</p>\n</h4>\n</header>\n<article>\n<p><a href=\"https://laohu8.com/S/TSLA\">Tesla</a>In the science and technology circle, it is a black online celebrity with hot topics.

OTA cars are also a double-edged sword.</p><p><img src=\"https://static.tigerbbs.com/b9e367c30b535b8c2a265e8ccd88751a\" tg-width=\"1000\" tg-height=\"616\" referrerpolicy=\"no-referrer\"></p><p>First of all, because of the mature R&D cycle and stable enterprise structure of traditional automobiles, there are too many newly matched components to realize OTA, and the cost of changing production lines and enterprise structures is too high. These new components need to undergo high-cost tests. After testing, automobile manufacturers will not integrate a bunch of untested \"semi-finished products\" and put them on the market, which will affect the safety of lives and property.</p><p>From the analysis of technical reasons, it is mainly related to the structure of traditional cars. Traditional cars are purely mechanical structures, and the power unit is very complex. The parameters such as fuel injection volume, braking system, shift logic, steering ratio, and suspension style are calibrated, and they need to be debugged and tested by engineers tens of millions of times to the best safe state before they can leave the factory. However, rebuilding OTA becomes unstable for power output and destroys the balanced parameter settings.</p><p>In addition to the security risks of physical hardware devices, OTA technology is at risk of being hacked during the remote upgrade process. In the process of downloading the upgrade package of the car, hackers can use network means to send the virus upgrade package to the vehicle, and then modify the system, remotely control and extort money. If you encounter some extreme weather or unstable environmental network, it will also lead to vulnerabilities in the upgrade package, which will cause the vehicle upgrade to fail.</p><p>We can see that OTA technology needs to go through a lot of security tests in the matching of physical equipment components themselves, as well as in the protocol and design process. No matter which link there is hidden danger in the link coupling between software and hardware devices, it is a matter of life and death for the safety of enterprises and vehicles. The problem cannot be played with. Take this recall of Tesla as an example. For the operation of ACC adaptive cruise control, the conventional design scheme of car companies is to use push-button or independent lever operation to turn on the adaptive cruise function. However, Tesla is prone to misoperation when using the adaptive cruise control function, which is a design logic defect. Tesla's solution is to raise the threshold of activating active cruise and add reminders of its activation and exit to avoid the possible recurrence of accidental touch.</p><p>If the logic setting of a small function is wrong, it will also bring irreparable results. Regarding safety issues, we cannot assume that everyone is cautious and does not have a short-circuit in their brains. If it is not uncommon to pay attention to vehicle-related news recalls, OTA can solve some software faults through upgrades, but whether it will bring new problems will also be an urgent problem to be solved. It can be seen that OTA technology is a double-edged sword for car companies, and it is meaningless to discuss whether it is absolutely safe. The road to intelligence of OTA cars will not be achieved overnight. Some system flaws need time to gradually iteratively optimize. After all, there is no product. It is perfect from the beginning of design.</p><p><img src=\"https://static.tigerbbs.com/e094f51a71e4d181f644eb1da3c657c5\" tg-width=\"1080\" tg-height=\"643\" referrerpolicy=\"no-referrer\"></p><p>At present, the development trend of the entire market is that car companies are gradually embracing OTA technology, and will not give up food because of local restrictions. OTA technology is becoming the standard feature of smart cars, and its technology penetration rate is particularly obvious. Statistics show that 30% of vehicles sold worldwide in 2020 have OTA functions. It will rise to 79% by 2025. According to data released by the Gaogong Intelligent Automobile Research Institute, the OTA installation rate of new cars in the Chinese market has reached 22.42% in 2020, and is expected to increase to 35-40% this year.</p><p>Although many car companies are trying their best to market OTA upgrade technology at the press conference, there are also many people swimming naked. Most car companies still stay at the SOTA upgrade level, that is, the functional upgrade at the entertainment and interaction level. There are only a handful of car companies that can upgrade the whole vehicle OTA. At present, upstarts such as Tesla, Ideal, XPeng, etc. have vehicle OTA capabilities. The OTA upgrade for the whole vehicle is a very significant sign that smart cars are different from traditional cars. From the perspective of the development history of OTA vehicles, the demand for OTA in the automotive industry is gradually developing from the parts level, vehicle level, and enterprise level to the industry ecological level. Traditional car companies such as BMW, Volkswagen, and SAIC-GM are actively reforming and reconstructing their electronic architecture in this major change to realize vehicle OTA.</p><p><b>The road to the future test of OTA cars</b></p><p>Nowadays, most car companies can achieve OTA of car-machine entertainment systems, that is, SOTA, but the real hard nut to crack is the whole vehicle FOTA. Because it involves the electronic architecture, hardware configuration and software self-research capabilities of vehicle manufacturers in new cars. The electronic controller needs to be deeply integrated with the update mechanism of the equipment. In what state the vehicle is flashed and written, and how to ensure the stability and safety of the update process. These implementation difficulties must be considered. For example, there are hundreds of ECUs (automotive electronic control components) of automobile interior components in the architecture of the whole vehicle, and they are connected in different communication networks. The data transmission protocols of each network are different and complicated. The more the upgraded controller considers, the more difficult it is to double the network communication topology protocols. OTA suppliers need to have a clear understanding of the characteristics of each communication line in order to efficiently realize software upgrades.</p><p><img src=\"https://static.tigerbbs.com/5529364f1b506bceb17619a2c75f3112\" tg-width=\"1080\" tg-height=\"600\" referrerpolicy=\"no-referrer\"></p><p>In terms of information security, in the process of OTA data transmission, there are potential risks of being counterfeited, stolen, and attacked. During the communication process, it will be held hostage and tampered with by malicious hackers, which may lead to abnormal vehicle operation, privacy leakage, financial and even life safety is threatened. It is particularly important to ensure the safety upgrade of OTA cars. OTA automobile manufacturers need to build a well-designed identification key technology architecture, and the limitation of verification mechanism and upgrade conditions requires two-way control to ensure an information security system integrating device and cloud.</p><p>The realization of OTA car functions relies on the development of various capabilities such as gateway protocols, network security, and continuous development of computing algorithm technology. Although electronic modules and software technologies develop together and are more and more applied in complete vehicles, the technology is still not mature. At the stage of widespread social recognition, the development of smart cars is long and long, and there is still a lot of room for updates and improvements. The optimization of OTA car functions and service differentiation need to evolve simultaneously. Fortunately, we will witness the surprises brought by OTA cars together.</p>\n<div class=\"bt-text\">\n\n\n<p> source：<a

3、国产Model Y电动汽车，共计285520辆，召回的主要原因是车辆存在主动巡航控制系统安全隐患，易造成驾驶员在转弯或者在D挡位情形误激活主动巡航功能，可能出现车辆速度突增情形，极端情况下可能导致车辆发生碰撞。\n看起来非常吓人，毕竟是关系到用车安全的问题。特斯拉此次的大规模召回不是物理上将车返厂返点的方式，而是通过汽车远程升级OTA的技术，用户无需到店即可完成在线升级。看似很严重的安全隐患仅仅通过OTA升级安全包的更新就可以解决问题吗？这种召回方式，没有车厂后续的常规安全测试，总觉得让人不安，甚至也会让人对OTA技术本身是否安全有疑虑。那么OTA系统到底安全吗？想要回答这个问题，先从什么是OTA汽车聊起。\nOTA汽车到底是什么？\nOTA的全称“Over-The-Air”，即空中下载技术（远程升级技术），通过无线网络下载数据包从而对系统更新进而改善终端功能和服务的技术。我们的电脑和手机进行系统更新的时候也是用的这个OTA技术。OTA进行系统升级的目的就是修复系统漏洞、优化改善以获得更多的功能、性能提升，又或者是视觉效果的改善，且这种更新是通过联网后在线检测、匹配版本、下载新的代码到本地进而执行安装、校验等程序。\n\nOTA技术最早应用于的汽车就是在2012年特斯拉推出的ModeL S上，内容更新范围包括人机交互、自动驾驶、动力电池系统等模块，当时特斯拉可以通过OTA完成钥匙卡漏洞、提升续航里程、提高最高速度、提升乘坐舒适度等。\n汽车OTA技术根据升级固件的差异，可以分为SOTA（Software OTA，软件空中升级）和FOTA（Firmware OTA，固件空中升级），即整车OTA。其中，SOTA只能对车辆应用层软件更新，仅限车机、信息娱乐等软件，几乎没有硬件调度的能力，车企实现难度较小，市面上经常看到宣传的OTA汽车大多数都是仅具有SOTA技术。而FOTA是对车辆控制器的系统层进行升级，影响的是车的动力系统、电池管理等系统，比如可以对底盘、动力、ADAS等底层系统进行OS层的软件更新。\n搭载OTA技术的汽车跟传统的汽车主要的区别是：在性能方面，搭载OTA技术的汽车车载实现的功能更丰富，总的来说是从这几方面实现功能：可以修复系统bug，更新驱动，优化UI界面，删除问题APP，大版本升级等。大多数车用OTA一般是针对娱乐系统、导航等推出在线系统更新。\n其次是车辆遇到软件故障或是需要更新时，传统汽车需要将车开到4S店利用专业电脑修复，耗费的时间精力，而搭载OTA技术的汽车可以足不出户就完成车辆升级，修复问题，节省成本与时间。比如OTA汽车可以对汽车的ECU软件进行更新。ECU是汽车电子控制器，通俗的来说就是汽车的大脑，新车出厂时动力不会完全发挥出来，通常会留下一部分可提升的空间，刷ECU就是通过一些技术手段，在原厂发动机能承受的基础上对ECU进行编码，达到提升马力或扭矩的目的，传统汽车想要刷ECU需要借助原厂的技术，OTA汽车可以在线升级这种能力。\n从上述的描述可以看出搭载OTA技术的车辆实现的功能以及便捷性让人心动与青睐，但是因为OTA技术本身涉及到对车辆物理性能比如ECU改变、电池性能改变、以及车辆软件体验功能的改变，在这其中，也有一些暗礁可能被触及。\nOTA汽车是把双刃剑\n从传统车企的保守选择来看，大家没有照单全收这些美好的体验，没有那么热衷搭载也是有原因的，OTA汽车也是把双刃剑。\n\n首先是因为传统汽车成熟的研发周期和稳定的企业架构，想要实现OTA需要新匹配的元器件太多，产线与企业结构的改变成本太大，这些新的元器件都需要经过高成本的测试，汽车厂商不会将一堆未经测试考验的“半成品”集成后推向市场，影响生命财产安全。\n从技术原因分析来看，主要是跟传统汽车的结构有关。传统的汽车都是纯机械结构，动力单元非常复杂，喷油量、刹车系统、换挡逻辑、转向比、悬挂风格等参数关系标定，需要被工程师千万次调试测试到最佳安全状态才能出厂。而重新搭建OTA对于动力输出来说变得不稳定，破坏平衡的参数设定。\n除了因为物理硬件设备的安全隐患外，OTA技术在远程升级过程中，有被黑客攻击的风险。汽车在下载升级包的过程中，黑客可以利用网络手段将被病毒升级包发送给车辆，进而修改系统、远程控制、勒索钱财。如果遇到一些极端天气或者环境网络不稳定的情况，也会导致升级包出现漏洞，进而使得车辆升级失败。\n我们可以看到OTA技术在物理设备元器件本身的匹配以及协议和设计过程需要经过大量的安全测试，软硬件设备之间的链接耦合无论是哪个环节存在隐患，对于企业和车辆的安全都是生死存亡的问题，不能儿戏。拿特斯拉汽车此次召回事件来说，ACC自适应巡航控制的操作,常规的车企设计方案是采用按键式或者独立拨杆的操作开启自适应巡航功能，但是特斯拉在使用自适应巡航控制功能的时候容易有误操作，这是一个设计逻辑上的缺陷，特斯拉的解决方案是提升激活主动巡航的阈值，加入了其激活和退出的提醒，避免误触的可能再发生。\n小小的一个功能逻辑设定有误的话，也会带来万劫不复的结果，对于安全问题，不能假设所有人都是小心谨慎没有大脑短路的时候。如果关注车辆相关的的新闻召回事件屡见不鲜，对于软件故障，OTA可以通过升级可以解决部分故障，但是是否还会带来新的问题，也会是个亟待解决的问题。可以看到OTA技术对于车企而言，是把双刃剑，讨论其是否绝对安全也没有意义，OTA汽车的智能化之路，不会一蹴而就，一些系统的瑕疵需要时间去逐渐迭代优化，毕竟没有任何产品在设计之初就是完美的。\n\n目前整个市场发展的趋势就是车企逐渐在拥抱OTA技术，不会因为局部的限制因噎废食。OTA技术正成为智能汽车标配， 其技术渗透率提升尤为明显。有数据显示，在2020年全球售出的车辆中，有30％具有OTA功能。到2025年，该比例将上升至79％。而根据高工智能汽车研究院发布的数据，2020年中国市场新车OTA搭载率已经达到22.42%，预计今年将提升至35-40%。\n尽管不少车企在发布会卖力营销OTA升级技术，但裸泳的人也不少，大多数车企还是停留在SOTA升级层面，也就是娱乐互动层面的功能升级，能够进行整车OTA升级的车企屈指可数。目前有着整车OTA能力的是特斯拉、理想、小鹏、等新贵。而面向于整车OTA升级，才是智能汽车区别于传统汽车的一个非常显著的标志。从OTA汽车的发展历程上来看，汽车行业对于OTA的需求是逐步由零部件级、整车级、企业级发展到行业生态级。宝马、大众、上汽通用等传统车企在这个大的变革中积极改革进行电子架构重构，以实现整车OTA。\nOTA汽车未来的大考之路\n现在大部分车企都能做到车机娱乐系统的OTA，也就是 SOTA，但真正难啃的硬骨头是整车FOTA。因为其涉及整车制造商在新车上的电子架构、硬件配置以及软件自研能力。电子控制器需要与设备的更新机制进行深度整合，车辆在什么状态下进行刷写，如何确保确保更新过程的稳定性与安全性，这些实现上的难点都是要考虑的。比如汽车内部件的ECU（汽车电子控制元器件），它们在整车的架构中数量为几百个，连接在不同的通讯网络中，每条网络的数据传输协议不同，比较复杂，升级的控制器越多考量的网络通讯拓扑结构协议翻番难度上升，需要OTA供应商对每条通讯线路的特点有清晰的认知才能高效地实现软件升级。\n\n在信息安全方面，OTA数据传输的过程中，有被仿冒、窃取、攻击的潜在风险，在通讯过程中会被不怀好意的黑客挟持与篡改，可能导致车辆运行异常、隐私泄露、财务甚至是生命安全受到威胁。保障OTA汽车的安全升级之路尤为重要。OTA汽车厂商需要搭建设计完善的标识秘钥技术架构，验证机制与升级条件的限定需要双向把控，才能保障端云一体的信息安全体系。\nOTA汽车功能的实现背后依托网关协议、网络安全、算力算法技术持续开发等多方面能力发展，虽然电子模块与软件技术协同发展，在整车上应用的越来越多，但技术还是没有成熟到社会广泛认同的阶段，智能汽车的发展之路长途漫漫，更新和改善的空间还是很大，OTA汽车功能上的优化，服务的差异化需要同步进化，幸运的是我们会一起见证OTA汽车带来的惊喜。","news_type":1,"symbols_score_info":{"TSLA":0.9}},"isVote":1,"tweetType":1,"viewCount":2280,"authorTweetTopStatus":1,"verified":2,"comments":[],"imageCount":0,"langContent":"EN","totalScore":0},{"id":437597964378304,"gmtCreate":1747809439877,"gmtModify":1747809441879,"author":{"id":"3568614602734225","authorId":"3568614602734225","name":"洞幽烛远","avatar":"https://static.tigerbbs.com/0e72968722642d797ced5fcb63f2fec1","crmLevel":11,"crmLevelSwitch":0,"followedFlag":false,"authorIdStr":"3568614602734225","idStr":"3568614602734225"},"themes":[],"htmlText":"<a

The real interest rate is equal to the nominal interest rate minus inflation expectations. When the nominal interest rate falls, gold continues to fall, and the price of gold has always had an inverse relationship with the real interest rate of the US Treasury Bond</b>That is to say, the real interest rate actually rises when the nominal interest rate falls, which can only show that the expectation of deflation is indeed relatively strong;</p><p><b>4. Expectations for a unilateral rise in commodities seem to no longer exist</b>, taking copper as an example, copper inventories on the London Metal Exchange increased by 24,925 tons, a surge of 17%. After a circle of research, it is said that it is because the supply and demand of copper itself are not so good. The reason why copper prices are strong depends largely on loose liquidity support. Under the expectation of price increases, the industrial chain buys up but not down, and inventories are all hidden, but now the Fed's rate hike expectations have advanced ahead of schedule, and the State Reserve has also sold inventories directly to downstream companies. When the price increase expectations are gone, the hidden inventories of hoarding goods are directly explicit, and the price increase expectations have been shaken.</p><p><b>5. Judging from the recent performance of the U.S. stock market, the market style preferences of U.S. stocks have also undergone significant changes, with the Nasdaq significantly outperforming the Dow</b>, the performance of growth is significantly stronger than cycle and value.</p><p>So, the question is, what happened to make market expectations change so quickly?</p><p>To answer this question, let's briefly analyze how inflation came about.</p><p><b>1. The origin of inflation</b></p><p>There is an essential difference between this round of quantitative easing in the United States and the 2008 financial crisis.</p><p>This time, the United States directly distributed the bills released by the Federal Reserve to residents through fiscal stimulus, while the quantitative easing of the 2008 financial crisis gave banknotes to financial institutions to help them deal with bad debts and illiquid assets.</p><p>Giving banknotes to residents can directly create aggregate demand, while giving banknotes to financial institutions can only create aggregate demand after the entity has financing needs.</p><p>Since the demand stimulation mode of helicopter money is divorced from the traditional historical experience, the speed of production adjustment is slower than the speed of demand expansion, which leads to supply chain bottlenecks and shortage of commodities at the production end.</p><p>Looking at the data of the US inventory-to-sales ratio can illustrate some problems. The seasonally adjusted inventory-to-sales ratio of retailers is the lowest, only 1.07, and the inventory of wholesalers is also relatively low, at 1.22. However, the inventory-to-sales ratio of manufacturers is as high as 1.48, which is still at a high level.</p><p><img src=\"https://static.tigerbbs.com/48ebb5dc27d1a4d9b56b06e650782960\" tg-width=\"590\" tg-height=\"375\" referrerpolicy=\"no-referrer\"></p><p>What does that mean?</p><p>This shows that after the United States issued welfare benefits, the American people's consumer demand for buy buy was too strong, resulting in retailers being bought out of stock. However, because the labor force is still receiving unemployment benefits, they are unwilling to come back to work, and those who come back to work are also Mainly in the service industry, not the manufacturing industry, coupled with expensive raw materials and tight transportation capacity, production has not recovered much.</p><p>The single-month retail sales data in the United States in May was US $620.2 billion, while the single-month retail sales data in the United States in 2019 was just over US $500 billion. Looking at the industrial production index, it was less than 100 in May, but it was around 102 in 2019.</p><p>In other words, consumption is far above pre-epidemic, but production has not yet returned to pre-epidemic.</p><p><img src=\"https://static.tigerbbs.com/acd06a9419c601db0a7cd0d4b4b66049\" tg-width=\"590\" tg-height=\"375\" referrerpolicy=\"no-referrer\"></p><p>Originally, import suppliers in the United States had more choices. For example, by attacking China's textile industry and pushing up upstream costs, China's industrial chain was forced to move out to places with lower labor costs (India, Southeast Asia). Since consumer demand is good and production is insufficient, how should the gap between supply and demand be met? We can only rely on imports.</p><p>Unexpectedly, the epidemic in India in April disrupted this plan. The epidemic not only appeared in India, but also quickly spread to Southeast Asian countries, Taiwan and Japan. These places are mostly production bases in the world. As a result, China's industrial chain not only did not move out, but instead further concentrated production resources domestically. FDI has recently It is accelerating the inflow into the country.</p><p><img src=\"https://static.tigerbbs.com/453c45b93dd234e782b6886c74a10046\" tg-width=\"589\" tg-height=\"299\" referrerpolicy=\"no-referrer\"></p><p>Since the gap in retail inventory in the United States is rigid, and countries and regions with production capacity have also been shut down due to the new round of epidemic, the gap in consumption and inventory in the United States can basically only be balanced by China's imports.</p><p><img src=\"https://static.tigerbbs.com/d0f6894c423cdb48c2a83c6b2eb33a26\" tg-width=\"588\" tg-height=\"321\" referrerpolicy=\"no-referrer\"></p><p><b>2. Unmovable orders</b></p><p>Now come back and look at the domestic.</p><p>Since China took the lead in controlling the epidemic, subsidized enterprises through credit during the epidemic, and maintained enterprises and production capacity. Therefore, from last year to now, China has been the backbone of stabilizing global inflation. The global supply system is highly dependent on China's production. Shipping costs have increased by more than 4-5 times compared with before the epidemic, and individual stocks related to shipping have also increased several times.</p><p><img src=\"https://static.tigerbbs.com/c2d563c458f06a2b983ad41fdf8636d9\" tg-width=\"588\" tg-height=\"295\" referrerpolicy=\"no-referrer\"></p><p>But looking at the current economic data, the new PMI export orders in May were only 48.3%, which was below the boom-and-dry line. Compared with the previous value of 50.4%, there was a more obvious downward trend. The export growth rate in May was 27.9%, which was not as good as the previous value of 32.3%. Now the market has begun to talk more about the peak of external demand.</p><p>From a logical and factual point of view, companies should not be short of orders, because overseas companies can only rely on China's production capacity at present.</p><p>We tend to think that the decline in new export orders is not because enterprises have no orders, but because enterprises dare not take orders easily.</p><p>Why are enterprises afraid to take orders? The main reason is that upstream commodities are sold too fast, and you lose money when you take orders.</p><p>There are three main reasons for the rapid rise in upstream commodity prices:</p><p>1. The demand of the United States can be printed by printing money. Most non-ferrous metals are priced in US dollars. The downward trend of the US dollar and the expansion of demand itself are good for upstream commodities.</p><p>2. Upstream supply cannot be opened, and some of them are unable to resume work due to the lack of vaccines in emerging markets. The spread of the epidemic in India has exacerbated this trend. For example, the semiconductor supply chain is tight, and the supply of scrap copper and some rare minerals has been disturbed; Some are because trade unions are strong; Others feel that demand is not sustainable. Good short-term demand is only printed by the United States and is not sustainable. Now it will be a matter of three years from the expansion of production capacity to the release of output, but if there is no such good demand in the future, You will lose money, so it is better to take advantage of the current price increase to maintain the oligopoly and earn enough cash flow now.</p><p>3. For domestic commodities with pricing power, due to the \"double carbon\" goal, safe production and other demands, the market is expected to reduce production, resulting in hidden inventories, and the downstream will also expect that supply will be in short supply in the future, so they can only panic stocking up at the moment, which intensifies expectations for upstream price increases.</p><p>From the data point of view, the PPI in May was as high as 9% year-on-year, while the CPI was only 1.3% year-on-year. Both the PMI raw material price minus the price of finished products and the PPI raw material price minus the PPI processing price hit a record high year-on-year, which shows that the downstream production and manufacturing links are constantly enduring upstream inflation.</p><p><img src=\"https://static.tigerbbs.com/bf605a70afe88045b7636a1a9c9e0b19\" tg-width=\"589\" tg-height=\"323\" referrerpolicy=\"no-referrer\"></p><p>But everything must have a degree.

The mysterious interest rate meeting</b></p><p>The most interesting thing about the June interest rate meeting is that Taper, which the market is paying attention to, basically didn't mention much, and the expression was very vague. It only said that the premise of opening Taper is to achieve the goal of \"substantial progress\" in the economy, and the standard of \"substantial progress\" It is determined by the Federal Reserve.</p><p>However, the most surprising thing about the June interest rate meeting was that rate hike's expectations were advanced. The number of members who believe that the rate hike should rise from 4 to 7 in 2022, and the number of members who should rate hike in 2023 will rise from 7 to 13.</p><p>On the whole, the interest rate meeting in June is to guide rate hike expectations ahead of schedule, and to \"keep silent\" about Taper, which the market is most concerned about.</p><p>The point is, what is the intention of the Fed in doing so?</p><p>After the interest rate meeting, the market followed a combination of a sharp rise in the US dollar and a decline in the 10-year U.S. bond yield. This trend combination is very confusing.</p><p>Let's first guess why the Fed kept silent about Taper.</p><p>In the first quarter, because the market formed optimistic expectations that the U.S. economy would recover rapidly after effective vaccination, the market's expectations for inflation were very high at that time, so the 10-year U.S. bond yield rose very quickly in the first quarter. In a few trading days, the yield rose from less than 1% to a high of 1.78% at the end of March.</p><p>However, the Federal Reserve believes that market expectations have gone too far, constantly emphasizing that inflation is temporary and does not cater to market expectations. In the second quarter, the Fed's balance sheet expansion also continued. Against the background of huge fiscal deposits, all kinds of short-term interest rates have been pressed to around 0.</p><p><img src=\"https://static.tigerbbs.com/f54f3462ee6ddf13338f6b301b11d78b\" tg-width=\"586\" tg-height=\"403\" referrerpolicy=\"no-referrer\"></p><p>There was a reason why the Fed did this in the second quarter. In the first quarter, although vaccines were being vaccinated rapidly, and the U.S. economy benefited from vaccines, it was indeed recovering rapidly, but both the number of jobs and wage growth were far from reaching pre-epidemic levels.</p><p>Withdrawing from easing means that the finance will decline, but there is still a high degree of uncertainty about whether the economic environment in the first quarter can absorb the labor force returning due to the withdrawal of welfare.</p><p>But by the end of the second quarter, it was obvious that the economy had tended to overheat, and the labor market began to be in short supply. Wages are rising at the same time that the number of job vacancies is rising.</p><p>Recently, the number of job vacancies in the United States has reached 9.29 million, compared with almost 7 million in 2019. The job vacancy rate is as high as 6%, and the average level in 2019 is around 4%.</p><p><img src=\"https://static.tigerbbs.com/f6fb48b1ad455cf8f930a98f6abb2752\" tg-width=\"591\" tg-height=\"349\" referrerpolicy=\"no-referrer\"></p><p>By this time, due to the overheating of the job market, the basis for the withdrawal of unemployment benefits has initially been met. What hinders the employment recovery is no longer the weak economic recovery, but the relief payments that even exceed the wages that many employers can pay, which leads to the slow recovery of the labor market. So starting in June, some states have begun to cancel the weekly unemployment benefit of $300.</p><p>We believe that Taper's \"silence\" and the Fed's goal of \"substantial progress\" in the economy most likely refers to a significant increase in employment data after the withdrawal of unemployment benefits, which can verify that the US economy is completely on the right track..</p><p>This is why this interest rate meeting did not raise the unemployment rate target, and remained at the unemployment level of 4.5% after the continued new jobs were lower than expected, because the Federal Reserve expects that after the withdrawal of unemployment benefits, the labor force will gradually return to the job market..</p><p>In short, only when there is a significant improvement in employment growth can the target conditions of \"substantial progress\" desired by the Fed be achieved. Only then will the Fed seriously consider whether the size of the quantitative easing should be reduced.</p><p>Let's review how inflation in the United States is formed.</p><p>The first is that the money printing machine sends money to residents, which leads consumers to \"buy in buy buy\"; The second is that local production has not been repaired, because the employment force has not returned, logistics costs are rising, and the supply of upstream raw materials is scarce (such as the lack of cores for cars and the lack of wood for building houses); The third is that raw material prices, freight and other costs have risen too fast, and China cannot accept new export orders.</p><p>Against the background of rapid demand expansion and relatively tight supply, we have seen that U.S. inflation has shown the characteristics of \"unlimited rise\". Since the supply simply can't match the expansion speed of demand, the residents can't buy the goods if they want to, and the price can only jump.</p><p>This is very similar to the U.S. real estate market. Existing home sales data have been declining since the beginning of this year, but this is not that demand has weakened, because the selling price of existing home sales is still accelerating, and at the same time, existing home inventories in the United States are being consumed.</p><p><img src=\"https://static.tigerbbs.com/95300d19a8a8ee5d831b8f969ae8b639\" tg-width=\"589\" tg-height=\"302\" referrerpolicy=\"no-referrer\"></p><p>In order to alleviate inflationary pressure, the logic is actually very simple. Either curb demand, such as paying less welfare, or guide employment to return to various positions and start production. As welfare goes down, demand weakens, and production increases, inflationary pressure naturally goes down.</p><p>The key now is whether the subsequent employment can increase, which in turn depends on:</p><p>1、<a href=\"https://laohu8.com/S/QC7.SI\">the whole people</a>After immunization, the intensity of the recovery of the U.S. service industry, if the production and supply of oil prices are relatively stable, the rise and fall of oil prices can be used as a high-frequency proxy indicator for the recovery of the service industry;</p><p>2. Have the small and medium-sized enterprises and supply chains in the United States suffered medium and long-term damage due to the epidemic? If so, the supply chain and production links in the United States cannot absorb much employment, and will not have the effect of repairing production.</p><p>These macroeconomic variables, at least from now on, are still uncertain. Only after unemployment benefits are withdrawn can the answer gradually become clear whether employment can increase.</p><p>Therefore, before employment is increased to fill the gap, the Federal Reserve will not be busy mentioning Taper, and it will not withdraw so quickly from providing benefits to residents. According to data from the U.S. Department of Labor, 70% of unemployment benefits will not be withdrawn until the end of the third quarter of this year.</p><p>If the United States can neither curb demand nor expand production scale in the short term, then there is only one way to alleviate inflation, reducing upstream costs, devaluing the exchange rate of producing countries, and replenishing retail inventories by expanding imports to producing countries.</p><p>That's why the Federal Reserve dare not mention Taper, because there is still some uncertainty about whether the job market can be repaired, but the Federal Reserve is willing to advance the market's rate hike expectations and pull up the US dollar, because this can not only devalue the exchange rate of producing countries and expand imports, but also suppress the price of upstream bulk goods, give some production profits to domestic and producing countries, and facilitate the reconstruction of retail inventory.</p><p><b>4. Market meaning</b></p><p>At this point in the story, we think the logic of the follow-up market is very clear.</p><p>At least in the short term, there is no need to pay too much attention to whether the Fed will Taper, because this will only happen after the confirmation of the employment gap repair, and then it will become the focus of market pricing.</p><p>The inflation or stagflation that everyone is hotly speculating about now is essentially the result of a sharp mismatch between supply and demand. When the elasticity of supply is weak to a certain extent, inflation appears in the form of \"unlimited rise\".</p><p>Therefore, the main contradiction in the global economy is no longer to continue to issue money to increase aggregate demand and keep prices going up, but to repair the fragile supply chain and ease inflation expectations through supply repair.</p><p>In other words, behind market pricing deflation is not necessarily the weakening of pricing economic demand, but more likely the short-term repair of pricing supply chain bottlenecks.</p><p>If the United States cannot rebuild its own inventory through the rebalancing of demand and production in the short term, solving the problem of supply chain bottlenecks needs to be solved by expanding imports.</p><p>As commodity prices rise, the cost of the production supply chain rises too fast to receive orders. From this perspective, suppressing the prices of upstream commodities will become the consensus of China and the United States at this stage.</p><p>At present, the focus of the wrestling between the two countries will not be \"pepper noodles\", but may be concentrated in the field of scientific and technological innovation that will form a \"technological generation gap\".</p><p>Therefore, it is best not to expect a unilateral rise in commodity prices at the moment. If commodity prices continue to rise unilaterally, there is a high probability that they will suffer losses.</p><p>In fact, the support for commodity price increases is not entirely due to how strong the current demand is. The expectation that demand exceeds supply plays a big role.</p><p>The low inventory of many commodities is not necessarily caused by the current strong demand and insufficient supply, but because there is an expectation that future demand will be far greater than supply, leading to downstream panic hoarding, superimposed traders' inventory hoarding, and rising prices leading to inventory. Implicit, and the hidden inventory further drives price increases.</p><p>Once the expectation of a unilateral price increase is gone, all the hidden inventory will run out.</p><p>If the United States needs to alleviate the contradiction between insufficient inventory of consumer goods through imports and RMB exchange rate depreciation, it means that there is no big problem for China's exports to remain high in the third quarter.</p><p>This round of domestic pressure on real estate and infrastructure, whether it is industrial production or manufacturing investment, is basically driven by exports. As long as exports can remain high, it means that the economic fundamentals in the third quarter are at least not weak.</p><p>As long as there are fundamentals, the risk appetite of stocks can be guaranteed, and if the upstream price increase can really be controlled, the profit margin of the middle and lower reaches will also come out. You can pay attention to the opportunities in the growth sector, especially the underlying core components and independent and controllable policy premium of materials.</p><p>Of course, the \"inflation trade\" can be paused for a while.</p>","source":"lsy1583127396478","collect":0,"html":"<!DOCTYPE html>\n<html>\n<head>\n<meta http-equiv=\"Content-Type\" content=\"text/html; charset=utf-8\" />\n<meta name=\"viewport\" content=\"width=device-width,initial-scale=1.0,minimum-scale=1.0,maximum-scale=1.0,user-scalable=no\"/>\n<meta name=\"format-detection\" content=\"telephone=no,email=no,address=no\" />\n<title>\"Inflation trading\" can be paused</title>\n<style type=\"text/css\">\na,abbr,acronym,address,applet,article,aside,audio,b,big,blockquote,body,canvas,caption,center,cite,code,dd,del,details,dfn,div,dl,dt,\nem,embed,fieldset,figcaption,figure,footer,form,h1,h2,h3,h4,h5,h6,header,hgroup,html,i,iframe,img,ins,kbd,label,legend,li,mark,menu,nav,\nobject,ol,output,p,pre,q,ruby,s,samp,section,small,span,strike,strong,sub,summary,sup,table,tbody,td,tfoot,th,thead,time,tr,tt,u,ul,var,video{ font:inherit;margin:0;padding:0;vertical-align:baseline;border:0 }\nbody{ font-size:16px; line-height:1.5; color:#999; background:transparent; }\n.wrapper{ overflow:hidden;word-break:break-all;padding:10px; }\nh1,h2{ font-weight:normal; line-height:1.35; margin-bottom:.6em; }\nh3,h4,h5,h6{ line-height:1.35; margin-bottom:1em; }\nh1{ font-size:24px; }\nh2{ font-size:20px; }\nh3{ font-size:18px; }\nh4{ font-size:16px; }\nh5{ font-size:14px; }\nh6{ font-size:12px; }\np,ul,ol,blockquote,dl,table{ margin:1.2em 0; }\nul,ol{ margin-left:2em; }\nul{ list-style:disc; }\nol{ list-style:decimal; }\nli,li p{ margin:10px 0;}\nimg{ max-width:100%;display:block;margin:0 auto 1em; }\nblockquote{ color:#B5B2B1; border-left:3px solid #aaa; padding:1em; }\nstrong,b{font-weight:bold;}\nem,i{font-style:italic;}\ntable{ width:100%;border-collapse:collapse;border-spacing:1px;margin:1em 0;font-size:.9em; }\nth,td{ padding:5px;text-align:left;border:1px solid #aaa; }\nth{ font-weight:bold;background:#5d5d5d; }\n.symbol-link{font-weight:bold;}\n/* header{ border-bottom:1px solid #494756; } */\n.title{ margin:0 0 8px;line-height:1.3;color:#ddd; }\n.meta {color:#5e5c6d;font-size:13px;margin:0 0 .5em; }\na{text-decoration:none; color:#2a4b87;}\n.meta .head { display: inline-block; overflow: hidden}\n.head .h-thumb { width: 30px; height: 30px; margin: 0; padding: 0; border-radius: 50%; float: left;}\n.head .h-content { margin: 0; padding: 0 0 0 9px; float: left;}\n.head .h-name {font-size: 13px; color: #eee; margin: 0;}\n.head .h-time {font-size: 12.5px; color: #7E829C; margin: 0;}\n.small {font-size: 12.5px; display: inline-block; transform: scale(0.9); -webkit-transform: scale(0.9); transform-origin: left; -webkit-transform-origin: left;}\n.smaller {font-size: 12.5px; display: inline-block; transform: scale(0.8); -webkit-transform: scale(0.8); transform-origin: left; -webkit-transform-origin: left;}\n.bt-text {font-size: 12px;margin: 1.5em 0 0 0}\n.bt-text p {margin: 0}\n</style>\n</head>\n<body>\n<div class=\"wrapper\">\n<header>\n<h2 class=\"title\">\n\"Inflation trading\" can be paused\n</h2>\n<h4 class=\"meta\">\n<p class=\"head\">\n<strong class=\"h-name small\">首席经济学家论坛</strong><span class=\"h-time small\">2021-06-23 10:35</span>\n</p>\n</h4>\n</header>\n<article>\n<p>While analysts and media comrades are still discussing \"inflation\" and \"stagflation\", the market is already trading deflation:</p><p><b>1.

The real interest rate is equal to the nominal interest rate minus inflation expectations. When the nominal interest rate falls, gold continues to fall, and the price of gold has always had an inverse relationship with the real interest rate of the US Treasury Bond</b>That is to say, the real interest rate actually rises when the nominal interest rate falls, which can only show that the expectation of deflation is indeed relatively strong;</p><p><b>4. Expectations for a unilateral rise in commodities seem to no longer exist</b>, taking copper as an example, copper inventories on the London Metal Exchange increased by 24,925 tons, a surge of 17%. After a circle of research, it is said that it is because the supply and demand of copper itself are not so good. The reason why copper prices are strong depends largely on loose liquidity support. Under the expectation of price increases, the industrial chain buys up but not down, and inventories are all hidden, but now the Fed's rate hike expectations have advanced ahead of schedule, and the State Reserve has also sold inventories directly to downstream companies. When the price increase expectations are gone, the hidden inventories of hoarding goods are directly explicit, and the price increase expectations have been shaken.</p><p><b>5. Judging from the recent performance of the U.S. stock market, the market style preferences of U.S. stocks have also undergone significant changes, with the Nasdaq significantly outperforming the Dow</b>, the performance of growth is significantly stronger than cycle and value.</p><p>So, the question is, what happened to make market expectations change so quickly?</p><p>To answer this question, let's briefly analyze how inflation came about.</p><p><b>1. The origin of inflation</b></p><p>There is an essential difference between this round of quantitative easing in the United States and the 2008 financial crisis.</p><p>This time, the United States directly distributed the bills released by the Federal Reserve to residents through fiscal stimulus, while the quantitative easing of the 2008 financial crisis gave banknotes to financial institutions to help them deal with bad debts and illiquid assets.</p><p>Giving banknotes to residents can directly create aggregate demand, while giving banknotes to financial institutions can only create aggregate demand after the entity has financing needs.</p><p>Since the demand stimulation mode of helicopter money is divorced from the traditional historical experience, the speed of production adjustment is slower than the speed of demand expansion, which leads to supply chain bottlenecks and shortage of commodities at the production end.</p><p>Looking at the data of the US inventory-to-sales ratio can illustrate some problems. The seasonally adjusted inventory-to-sales ratio of retailers is the lowest, only 1.07, and the inventory of wholesalers is also relatively low, at 1.22. However, the inventory-to-sales ratio of manufacturers is as high as 1.48, which is still at a high level.</p><p><img src=\"https://static.tigerbbs.com/48ebb5dc27d1a4d9b56b06e650782960\" tg-width=\"590\" tg-height=\"375\" referrerpolicy=\"no-referrer\"></p><p>What does that mean?</p><p>This shows that after the United States issued welfare benefits, the American people's consumer demand for buy buy was too strong, resulting in retailers being bought out of stock. However, because the labor force is still receiving unemployment benefits, they are unwilling to come back to work, and those who come back to work are also Mainly in the service industry, not the manufacturing industry, coupled with expensive raw materials and tight transportation capacity, production has not recovered much.</p><p>The single-month retail sales data in the United States in May was US $620.2 billion, while the single-month retail sales data in the United States in 2019 was just over US $500 billion. Looking at the industrial production index, it was less than 100 in May, but it was around 102 in 2019.</p><p>In other words, consumption is far above pre-epidemic, but production has not yet returned to pre-epidemic.</p><p><img src=\"https://static.tigerbbs.com/acd06a9419c601db0a7cd0d4b4b66049\" tg-width=\"590\" tg-height=\"375\" referrerpolicy=\"no-referrer\"></p><p>Originally, import suppliers in the United States had more choices. For example, by attacking China's textile industry and pushing up upstream costs, China's industrial chain was forced to move out to places with lower labor costs (India, Southeast Asia). Since consumer demand is good and production is insufficient, how should the gap between supply and demand be met? We can only rely on imports.</p><p>Unexpectedly, the epidemic in India in April disrupted this plan. The epidemic not only appeared in India, but also quickly spread to Southeast Asian countries, Taiwan and Japan. These places are mostly production bases in the world. As a result, China's industrial chain not only did not move out, but instead further concentrated production resources domestically. FDI has recently It is accelerating the inflow into the country.</p><p><img src=\"https://static.tigerbbs.com/453c45b93dd234e782b6886c74a10046\" tg-width=\"589\" tg-height=\"299\" referrerpolicy=\"no-referrer\"></p><p>Since the gap in retail inventory in the United States is rigid, and countries and regions with production capacity have also been shut down due to the new round of epidemic, the gap in consumption and inventory in the United States can basically only be balanced by China's imports.</p><p><img src=\"https://static.tigerbbs.com/d0f6894c423cdb48c2a83c6b2eb33a26\" tg-width=\"588\" tg-height=\"321\" referrerpolicy=\"no-referrer\"></p><p><b>2. Unmovable orders</b></p><p>Now come back and look at the domestic.</p><p>Since China took the lead in controlling the epidemic, subsidized enterprises through credit during the epidemic, and maintained enterprises and production capacity. Therefore, from last year to now, China has been the backbone of stabilizing global inflation. The global supply system is highly dependent on China's production. Shipping costs have increased by more than 4-5 times compared with before the epidemic, and individual stocks related to shipping have also increased several times.</p><p><img src=\"https://static.tigerbbs.com/c2d563c458f06a2b983ad41fdf8636d9\" tg-width=\"588\" tg-height=\"295\" referrerpolicy=\"no-referrer\"></p><p>But looking at the current economic data, the new PMI export orders in May were only 48.3%, which was below the boom-and-dry line. Compared with the previous value of 50.4%, there was a more obvious downward trend. The export growth rate in May was 27.9%, which was not as good as the previous value of 32.3%. Now the market has begun to talk more about the peak of external demand.</p><p>From a logical and factual point of view, companies should not be short of orders, because overseas companies can only rely on China's production capacity at present.</p><p>We tend to think that the decline in new export orders is not because enterprises have no orders, but because enterprises dare not take orders easily.</p><p>Why are enterprises afraid to take orders? The main reason is that upstream commodities are sold too fast, and you lose money when you take orders.</p><p>There are three main reasons for the rapid rise in upstream commodity prices:</p><p>1. The demand of the United States can be printed by printing money. Most non-ferrous metals are priced in US dollars. The downward trend of the US dollar and the expansion of demand itself are good for upstream commodities.</p><p>2. Upstream supply cannot be opened, and some of them are unable to resume work due to the lack of vaccines in emerging markets. The spread of the epidemic in India has exacerbated this trend. For example, the semiconductor supply chain is tight, and the supply of scrap copper and some rare minerals has been disturbed; Some are because trade unions are strong; Others feel that demand is not sustainable. Good short-term demand is only printed by the United States and is not sustainable. Now it will be a matter of three years from the expansion of production capacity to the release of output, but if there is no such good demand in the future, You will lose money, so it is better to take advantage of the current price increase to maintain the oligopoly and earn enough cash flow now.</p><p>3. For domestic commodities with pricing power, due to the \"double carbon\" goal, safe production and other demands, the market is expected to reduce production, resulting in hidden inventories, and the downstream will also expect that supply will be in short supply in the future, so they can only panic stocking up at the moment, which intensifies expectations for upstream price increases.</p><p>From the data point of view, the PPI in May was as high as 9% year-on-year, while the CPI was only 1.3% year-on-year. Both the PMI raw material price minus the price of finished products and the PPI raw material price minus the PPI processing price hit a record high year-on-year, which shows that the downstream production and manufacturing links are constantly enduring upstream inflation.</p><p><img src=\"https://static.tigerbbs.com/bf605a70afe88045b7636a1a9c9e0b19\" tg-width=\"589\" tg-height=\"323\" referrerpolicy=\"no-referrer\"></p><p>But everything must have a degree.

So starting in June, some states have begun to cancel the weekly unemployment benefit of $300.</p><p>We believe that Taper's \"silence\" and the Fed's goal of \"substantial progress\" in the economy most likely refers to a significant increase in employment data after the withdrawal of unemployment benefits, which can verify that the US economy is completely on the right track..</p><p>This is why this interest rate meeting did not raise the unemployment rate target, and remained at the unemployment level of 4.5% after the continued new jobs were lower than expected, because the Federal Reserve expects that after the withdrawal of unemployment benefits, the labor force will gradually return to the job market..</p><p>In short, only when there is a significant improvement in employment growth can the target conditions of \"substantial progress\" desired by the Fed be achieved. Only then will the Fed seriously consider whether the size of the quantitative easing should be reduced.</p><p>Let's review how inflation in the United States is formed.</p><p>The first is that the money printing machine sends money to residents, which leads consumers to \"buy in buy buy\"; The second is that local production has not been repaired, because the employment force has not returned, logistics costs are rising, and the supply of upstream raw materials is scarce (such as the lack of cores for cars and the lack of wood for building houses); The third is that raw material prices, freight and other costs have risen too fast, and China cannot accept new export orders.</p><p>Against the background of rapid demand expansion and relatively tight supply, we have seen that U.S. inflation has shown the characteristics of \"unlimited rise\". Since the supply simply can't match the expansion speed of demand, the residents can't buy the goods if they want to, and the price can only jump.</p><p>This is very similar to the U.S. real estate market. Existing home sales data have been declining since the beginning of this year, but this is not that demand has weakened, because the selling price of existing home sales is still accelerating, and at the same time, existing home inventories in the United States are being consumed.</p><p><img src=\"https://static.tigerbbs.com/95300d19a8a8ee5d831b8f969ae8b639\" tg-width=\"589\" tg-height=\"302\" referrerpolicy=\"no-referrer\"></p><p>In order to alleviate inflationary pressure, the logic is actually very simple. Either curb demand, such as paying less welfare, or guide employment to return to various positions and start production. As welfare goes down, demand weakens, and production increases, inflationary pressure naturally goes down.</p><p>The key now is whether the subsequent employment can increase, which in turn depends on:</p><p>1、<a href=\"https://laohu8.com/S/QC7.SI\">the whole people</a>After immunization, the intensity of the recovery of the U.S. service industry, if the production and supply of oil prices are relatively stable, the rise and fall of oil prices can be used as a high-frequency proxy indicator for the recovery of the service industry;</p><p>2. Have the small and medium-sized enterprises and supply chains in the United States suffered medium and long-term damage due to the epidemic? If so, the supply chain and production links in the United States cannot absorb much employment, and will not have the effect of repairing production.</p><p>These macroeconomic variables, at least from now on, are still uncertain. Only after unemployment benefits are withdrawn can the answer gradually become clear whether employment can increase.</p><p>Therefore, before employment is increased to fill the gap, the Federal Reserve will not be busy mentioning Taper, and it will not withdraw so quickly from providing benefits to residents. According to data from the U.S. Department of Labor, 70% of unemployment benefits will not be withdrawn until the end of the third quarter of this year.</p><p>If the United States can neither curb demand nor expand production scale in the short term, then there is only one way to alleviate inflation, reducing upstream costs, devaluing the exchange rate of producing countries, and replenishing retail inventories by expanding imports to producing countries.</p><p>That's why the Federal Reserve dare not mention Taper, because there is still some uncertainty about whether the job market can be repaired, but the Federal Reserve is willing to advance the market's rate hike expectations and pull up the US dollar, because this can not only devalue the exchange rate of producing countries and expand imports, but also suppress the price of upstream bulk goods, give some production profits to domestic and producing countries, and facilitate the reconstruction of retail inventory.</p><p><b>4. Market meaning</b></p><p>At this point in the story, we think the logic of the follow-up market is very clear.</p><p>At least in the short term, there is no need to pay too much attention to whether the Fed will Taper, because this will only happen after the confirmation of the employment gap repair, and then it will become the focus of market pricing.</p><p>The inflation or stagflation that everyone is hotly speculating about now is essentially the result of a sharp mismatch between supply and demand. When the elasticity of supply is weak to a certain extent, inflation appears in the form of \"unlimited rise\".</p><p>Therefore, the main contradiction in the global economy is no longer to continue to issue money to increase aggregate demand and keep prices going up, but to repair the fragile supply chain and ease inflation expectations through supply repair.</p><p>In other words, behind market pricing deflation is not necessarily the weakening of pricing economic demand, but more likely the short-term repair of pricing supply chain bottlenecks.</p><p>If the United States cannot rebuild its own inventory through the rebalancing of demand and production in the short term, solving the problem of supply chain bottlenecks needs to be solved by expanding imports.</p><p>As commodity prices rise, the cost of the production supply chain rises too fast to receive orders. From this perspective, suppressing the prices of upstream commodities will become the consensus of China and the United States at this stage.</p><p>At present, the focus of the wrestling between the two countries will not be \"pepper noodles\", but may be concentrated in the field of scientific and technological innovation that will form a \"technological generation gap\".</p><p>Therefore, it is best not to expect a unilateral rise in commodity prices at the moment. If commodity prices continue to rise unilaterally, there is a high probability that they will suffer losses.</p><p>In fact, the support for commodity price increases is not entirely due to how strong the current demand is. The expectation that demand exceeds supply plays a big role.</p><p>The low inventory of many commodities is not necessarily caused by the current strong demand and insufficient supply, but because there is an expectation that future demand will be far greater than supply, leading to downstream panic hoarding, superimposed traders' inventory hoarding, and rising prices leading to inventory. Implicit, and the hidden inventory further drives price increases.</p><p>Once the expectation of a unilateral price increase is gone, all the hidden inventory will run out.</p><p>If the United States needs to alleviate the contradiction between insufficient inventory of consumer goods through imports and RMB exchange rate depreciation, it means that there is no big problem for China's exports to remain high in the third quarter.</p><p>This round of domestic pressure on real estate and infrastructure, whether it is industrial production or manufacturing investment, is basically driven by exports. As long as exports can remain high, it means that the economic fundamentals in the third quarter are at least not weak.</p><p>As long as there are fundamentals, the risk appetite of stocks can be guaranteed, and if the upstream price increase can really be controlled, the profit margin of the middle and lower reaches will also come out. You can pay attention to the opportunities in the growth sector, especially the underlying core components and independent and controllable policy premium of materials.</p><p>Of course, the \"inflation trade\" can be paused for a while.</p>\n<div class=\"bt-text\">\n\n\n<p> source：<a

FDI近期是加速往国内流入的。\n\n由于美国的零售品库存的缺口是刚性的，拥有生产能力的国家和地区也因新一轮疫情停摆，美国消费和库存的缺口基本上只能靠中国的进口来平衡了。\n\n二、接不动的订单\n现在回来看看国内。\n由于中国率先控制了疫情，疫情期间通过信贷补贴了企业，保住了企业和生产能力，所以从去年到现在，中国一直都是稳定全球通胀的中坚力量，全球的供应体系高度依赖于中国的生产，海运费用比疫情前涨了4-5倍都不止，和海运相关的个股涨幅也有好几倍。\n\n但看现在的经济数据，5月PMI新出口订单只有48.3%，到了枯荣线的下面，相比前值50.4%，有较为明显的下行。5月的出口增速为27.9%，也不如前值的32.3%，现在市场关于外需的见顶讨论开始多了起来。\n从逻辑和事实上来讲，企业应该是不会缺订单的，因为当下海外只能依赖中国的产能。\n我们倾向于认为出口新订单的下降不是因为企业没有订单，而是企业不敢轻易接订单了。\n企业为什么不敢接订单呢？主要原因是上游大宗商品上得太快了，接单就亏钱。\n上游大宗商品价格涨得快的原因主要有三个：\n1、美国的需求可以靠印钞票印出来，大多数有色金属是美元定价，美元下行和需求扩张本身就利好上游大宗商品。\n2、上游供给打不开，有的是因为新兴市场缺少疫苗导致无法复工，印度疫情扩散加剧了这一趋势，比如半导体供应链紧张、废铜还有一些稀有矿的供给都受到了扰动；有的是因为工会强势；还有的是觉得需求没有持续性，短期需求好只是美国印出来的，没有可持续性，现在扩产能到产出释放都是未来三年以后的事了，但未来如果没有这么好的需求，就会赔钱，所以不如趁现在价格涨维持寡头垄断，当下赚足现金流就好。\n3、国内有定价权的大宗商品，因“双碳”目标、安全生产等诉求，市场有减产预期，导致库存隐性化，而且下游也会预期未来供应会紧缺，只能当下恐慌性备货，使得上游价格上涨预期加剧。\n从数据来看，5月PPI同比高达9%，而CPI同比仅为1.3%，无论是PMI原材料价格减去产成品价格还是PPI原材料价格同比减去PPI加工价格同比都创下了历史新高，这说明下游生产制造环节在不断忍受着上游的通胀。\n\n但凡事都得有个度，当上游上涨的矛盾积累到了一定程度后，企业长期“增收不增利”、“吃力不讨好”，自然就不敢接订单了，因为订单接得越多，反而会越赔钱。\n\n三、谜一样的议息会议\n6月议息会议最有趣的一点就是市场关注的Taper基本上没怎么提，表述很模糊，只说Taper开启的前提是达到经济取得“实质性进展”的目标，而“实质性进展”的标准是由美联储决定的。\n但6月议息会议最让市场意外的一点是加息预期提前了，认为2022年应当加息的成员从4人上升到了7人，2023年应当加息的成员从7人上升到了13人。\n综合来看，6月议息会议是引导加息预期提前，并且对市场最关注的Taper“闭口不提”。\n关键是，美联储这么做的意图是什么？\n议息会议后，市场走的是美元大幅上涨而10年美债收益率下行的组合，这种走势组合让人很疑惑。\n先来猜测一下，美联储为什么对Taper闭口不提。\n一季度的时候，因为市场形成了疫苗有效接种后美国经济会快速复苏的乐观预期，当时市场对通胀的预期很靠前，所以一季度10年期美债收益率上升的速度非常快，没几个交易日就从不到1%的收益率上行到了3月末1.78%的高点。\n但美联储认为市场预期走得太前了，不断在强调通胀是暂时的，没有去迎合市场预期。二季度美联储的扩表也在继续，在财政存款巨量投放的背景下，各类短端利率都压到了0附近。\n\n二季度美联储这么做也是有原因的。一季度的时候，疫苗虽然在快速接种，美国经济受益于疫苗，确实是在快速修复，但无论是就业数量还是薪资增速，都远没有达到疫情前的水平。\n退出宽松就意味着财政要退坡，但一季度的经济环境是否能吸纳因福利退出而回流的劳动力大军，还是有很高的不确定性的。\n但到了二季度末，很明显可以看到经济已经有了过热的倾向，劳动力市场开始供不应求。工资上涨的同时职位空缺人数也在不断上升。\n近期美国就业职位空缺人数已高达929万人，而2019年差不多就700万人左右，职位空缺率高达6%，而2019年的平均水平也就在4%左右的水平。\n\n到了这个时候，由于就业市场过热，已初步具备失业救济退出的基础。阻碍就业复苏的不再是经济复苏不给力，而是救济金甚至超过了许多雇主可以支付的工资，才导致劳动力市场复苏缓慢。所以从6月开始，已经有部分州开始取消每周300美元的失业救济金。\n我们认为Taper“闭口不提”，美联储要的经济“实质性进展”的目标，大概率指的是失业救济退出以后，就业数据要出现明显的新增，这才能验证美国经济已经彻底走上正轨。\n这也是为什么此次议息会议并没有上调失业率目标，在持续的新增就业低于预期之后还维持在4.5%的失业水平，因为美联储预期失业救济退出之后，劳动力就会逐步回归到就业市场。\n简而言之，只有等到就业新增真的有明显改善后，才能达到美联储要的“实质性进展”的目标条件。也只有等到那个时候，美联储才会认真考虑量化宽松规模是不是要缩减。\n下面我们再来回顾一下美国的通胀是怎么形成的。\n第一个是印钞机给居民发钱导致消费者“买买买”；第二个是本土生产没有修复，因为就业大军没有回归的、物流成本上升和上游原材料供给稀缺（比如汽车缺芯、盖房子缺木材）；第三个是原材料价格、运费等各类成本涨得太快，中国也接不动出口新订单。\n在需求扩张较快和供应相对紧缺的背景下，我们看到美国通胀呈现出了“无量上涨”的特征。由于供给根本匹配不上需求的扩张的速度，居民部门想买都买不到货，价格就只能跳涨了。\n这跟美国房地产市场很像，成屋销售数据从今年年初就开始下降了，但这并不是需求减弱了，因为成屋销售的售价还在加速上行，与此同时，美国成屋库存在被消耗。\n\n要想缓解通胀压力，其实逻辑也很简单，要么抑制需求，比如少发点福利，要么引导就业回归到各个岗位上去，把生产弄起来。福利下去了，需求弱了，而生产变多了，通胀压力自然就下去了。\n现在的关键就是后续就业新增能不能上去，这又取决于：\n1、全民免疫后，美国服务业复苏的强度，如果油价生产供应比较稳定，油价涨跌可以作为服务业修复高频代理指标；\n2、美国的中小企业和供应链是不是因为疫情受到了中长期损害，如果是的话，美国的供应链和生产环节吸纳不了多少就业，也就起不到修复生产的效果。\n这些宏观经济变量，至少从现在来看，还是有不确定性的，要等到失业救济退出后，就业能否放量，答案才能逐渐明晰。\n所以，在就业放量补缺口前，美联储是不会忙着提Taper的，给居民部门发福利也不会那么快退出。从美国劳工部的数据来看，70%的失业救济到了今年三季度末才会陆续退出。\n如果美国短期既做不到抑制需求，也无法扩大生产规模，那缓解通胀就只有一个办法，降上游成本，让生产国的汇率贬值，通过扩大对生产国的进口来补充零售的库存。\n这就是为什么美联储不敢提Taper,因为就业市场能不能修复还有一定的不确定，但美联储愿意把市场的加息预期提前，把美元拉上去，因为这样既可以让生产国的汇率贬值进而扩大进口，也可以打压一下上游大宗的价格，给本国和生产国一些生产的利润，方便重建零售库存。\n四、市场含义\n故事讲到这里，我们认为后续市场的逻辑就非常清晰了。\n至少在短期，没有过于关注美联储是否会Taper的必要，因为这个需要就业缺口修复的确认后才会发生，然后才会成为市场定价的焦点。\n现在大家都热炒的通胀或滞胀，本质上都是供需急剧错配的结果，当供给的弹性弱到一定程度以后，通胀是以“无量上涨”的形式出现的。\n所以，现在全球经济的主要矛盾不再是要继续发钞票去拉高总需求，让物价继续往上走，而是修复脆弱的供应链，通过供给修复来缓和通胀的预期。\n换言之，市场定价通缩的背后不一定是在定价经济需求的走弱，更有可能是在定价供应链瓶颈的短期修复。\n如果美国短期无法通过需求生产的再平衡重建自身的库存，解决供应链瓶颈的问题就需要通过扩大进口来解决。\n由于大宗商品价格上涨使得生产供应链的成本攀升太快，接不动订单，从这个角度来看，打压上游大宗商品的价格在现阶段会成为中美两国的共识。\n两国角力的重点，在当下也不会是“撒胡椒面”式的，而是有可能集中在会形成“技术代差”的科技创新领域。\n所以，当下最好别有大宗商品价格单边上涨的预期，赌大宗商品价格继续单边上涨大概率是会吃亏的。\n其实大宗商品涨价的支撑也不完全是因为当前的需求有多强，求大于供的预期起到了很大的作用。\n很多大宗商品的低库存并一定是因为当下需求旺盛而供应不足导致的，而是因为存在未来需求会远大于供给的预期，导致下游恐慌性囤货，叠加贸易商库存囤积，价格上涨导致库存隐性化，而库存隐性化又进一步驱动了价格上涨。\n一旦价格单边上涨的预期没了，隐藏的库存就都跑出来了。\n如果说美国需要通过进口和人民币汇率贬值来缓解消费品库存不足的矛盾，这意味着中国三季度出口维持高位的问题不大。\n这一轮国内压着房地产和基建，无论是工业生产还是制造业投资，基本上是靠出口驱动的，只要出口还能维持高位，那就意味着三季度经济基本面至少是不弱的。\n只要有基本面搭台，股票的风险偏好就能有保障，而且上游价格涨幅如果真能控制，中下游的盈利空间也就出来了，可以关注成长板块的机会，尤其要关注底层核心零部件和材料自主可控的政策溢价。\n当然，“通胀交易”可以暂歇了。","news_type":1,"symbols_score_info":{"161125":0.9,"513500":0.9,"TQQQ":0.9,"DJX":0.9,"ZFmain":0.9,"SQQQ":0.9,"ESmain":0.9,"PSQ":0.9,".SPX":0.9,"UPRO":0.9,"ZNmain":0.9,"ZBmain":0.9,"ZTmain":0.9,"DXD":0.9,"OEX":0.9,"QID":0.9,"SSO":0.9,"UBmain":0.9,".IXIC":0.9,"SPXU":0.9,"OEF":0.9,"TNmain":0.9,"MNQmain":0.9,"SDS":0.9,"DDM":0.9,"SDOW":0.9,"SPY":0.9,"SH":0.9,"DOG":0.9,"QLD":0.9,"QQQ":0.9,"IVV":0.9,"NQmain":0.9,"UDOW":0.9}},"isVote":1,"tweetType":1,"viewCount":1768,"authorTweetTopStatus":1,"verified":2,"comments":[],"imageCount":0,"langContent":"EN","totalScore":0}],"lives":[]}
