因芯片短缺和原材料涨价，特斯拉频繁上调车型售价。自2020年“新冠”疫情全球大流行以来，全球芯片产业链产能持续遭受考验，而中美贸易摩擦以及芯片主产地相继遭受多种灾害，更是加剧了全球芯片供给不足的紧张状况，从而进一步加重全球汽车芯片短缺的阶段性危机。2021年5月8日，特斯拉中国宣布，国产Model 3标准续航升级版上涨1000元，这是2021年以来国产特斯拉的第二次涨价。近两个月，特斯拉在美国连续多次涨价。频繁上调价格的背后是芯片短缺和原材料涨价造成的零部件价格上涨。

Demand for earthmoving and concrete machinery increased in China, North America, and LATAM with residential, industrial, and mining activities resuming rapidly from mid-2020. Early 2021 had seen less operations, with curfews in many regions. Construction, mining, and farming activities are resuming in India, China, US, and South America, which is expected to aid the recovery of OHW by unit shipment growth 7.4% (2020 to 2021).

近年来，伴随“中国制造2025”、“互联网+”、深化制造业与互联网融合发展等国家战略的推动部署，以及汽车、电子、信息通信等技术的发展，我国车联网技术和产业发展迅速。与此同时，我国车联网发展也面临着巨大的安全挑战。安全作为车联网健康发展的基础和保障，已成为当前研究的热点和难点。在此背景下，本文首先梳理了当前车联网网络安全态势，分析了车联网面临的安全风险和挑战，对车联网安全防护的关键技术及解决方案进行了梳理和总结，并提出我国车联网安全发展的对策建议。

Automotive key & lock market is highly application driven and systems are gaining popularity across end users and technologies such as Infra-Red Sensor, Transmission and Others. Technological advancements along with the demand for convenience are the key factors are driving the growth of automotive smart key market. Asia-Pacific is estimated to account for the largest share of the automotive smart key system market. This can mainly be attributed to the rising vehicle production and the increasing installation of safety features in passenger cars, commercial vehicles. Additionally, high demand from customers and high purchasing power has upped the demand for vehicles and boosted the market for automotive smart key. The Europe and North American market are expected to experience a steady level of growth. Manufacturers are implementing IoT to offer connected car applications for drivers such as fuel tracking, Advanced Driver-Assistance Systems (ADAS), speed control, and invehicle infotainment systems. Automotive digital key, one of the new innovations resulting from the adoption of IoT, is therefore expected to gain momentum among auto manufacturers and consumers in the coming years

疫情影响下，汽车芯片在马来西亚的封装受到较大程度影响，行业复苏的时间点比我们预计的要向后推迟，但复苏的逻辑并没有破坏。复苏有推迟但仍会到来。疫情影响下，汽车芯片在马来西亚的封装受到较大程度影响，行业复苏的时间点比我们预计的要向后推迟，但复苏的逻辑并没有破坏。继续推荐“自主品牌+汽技+高景气度细分产业链”三条投资主线。

新能源车较传统燃油车在结构上发生重大变化，以动力总成（电机、电控、电池）为代表的零部件均需定制化开发机床进行加工，进而催生机床新需求。根据我们测算，2021-2025年新能源车领域新增机床需求为265亿元，年均53亿元。一体化压铸是对传统汽车制造工艺（冲压+焊接）的颠覆，其在成本、效率、加工质量等方面拥有巨大优势，未来在新能源车领域有望快速渗透。一体化压铸成型后，需要配套相应机床进行压铸件的毛刺与毛边等的切削，若考虑该工艺用于整车加工，根据我们测算，中国年产 800万辆新能源车对应机床（以龙门为主）总需求在440亿元左右，年均为88亿元。预计从2022年开始，随着其他新能源车厂商逐步跟进推动一体压铸工艺，相关机床需求将迎来爆发。

国外厂商领先，国产替代空间广阔。1）2019 年全球汽车连接器厂商 TOP10 以美、日企业为主，泰科、矢崎、安波福三巨头市占率之和达
67%。汽车连接器行业国产化率较低，我们估算中国市场中高速连接器国产化率仅 5%、高压连接器国产化率不足 30%。2）考虑新能源车产品迭代速度更快，国内企业响应速度更快、服务能力更强、成本控制更优，国内汽车汽车连接器企业有望实现快速成长。3）在中国企业中，高压连接器的佼佼者是中航光电、瑞可达，高速连接器中电连技术实力突出。
