3. Necessity of project implementation
(1) The project is an important measure to closely follow national policies and realize domestic substitution
Considering the safety performance in special working environment, automobile chip has the characteristics of high technical standard and long test cycle. Infineon, Texas Instruments and other foreign leading manufacturers monopolize more than half of the international market share of automotive chips by virtue of the first mover advantage. China’s chip design industry started relatively late and is still in the growth stage of technological breakthrough in the field of automotive electronics, with a low market share. As the world’s largest automobile producer and the world’s largest automobile consumer market, China’s automobile chips at the upstream of the industrial chain still rely on imports for a long time, and the automobile electronic system is the core and foundation of the automobile industrial chain. Under the background of Sino US trade disputes, the localization of automobile chips is an inevitable requirement to ensure the long-term and healthy development of the automobile industry, and the domestic substitution of automobile chips has risen to the national strategic level. On February 24, 2020, the national development and Reform Commission and other 11 ministries and commissions jointly issued the intelligent vehicle innovation and development strategy, which clearly proposed to break through key technologies such as intelligent computing platform and vehicle specification chip. In September 2020, the Ministry of science and technology, the Ministry of industry and information technology and the national innovation center established the China Automotive chip innovation alliance in Beijing, which aims to establish the innovation ecology of China’s automotive chip industry, break industry barriers, supplement industry weaknesses, and realize the independent, safe, controllable, comprehensive and rapid development of China’s automotive chip industry. The layout of the project in the automotive field and the improvement of the automotive electronic product line comparable to international giants are important measures to closely follow national policies and realize domestic substitution in the semiconductor industry.
(2) The layout of the field of new energy vehicles is an effective measure for the company to grasp the development opportunities of the industry and promote business development
With the rise of new energy vehicles and intelligent driving, the proportion of electronic and electrical applications in the whole vehicle is increasing. The electrification, networking, intelligence and sharing of automobiles have brought new application scenarios and existing configuration upgrades. Increasingly powerful processors and increasing system peripherals have put forward higher requirements for power management. These new applications are also the best entry opportunities for Chinese automobile chip manufacturers, which will promote the market scale of vehicle specification power supply and electric drive power chip into a new stage of development. At the same time, compared with traditional fuel vehicles, new energy vehicles have added “three electricity” systems of battery, motor and electronic control, driving a large amount of demand for electric energy conversion, so as to promote the significant incremental demand of the upstream chip market.
The company will take the field of high-voltage power supply and high-voltage drive that it is good at as the entry point, based on the existing vehicle specification level technical reserves, expand the scale of R & D team, actively explore the in-depth application of power chips in the automotive field, and form a complete power solution. The implementation of the project will help the company grasp the industry opportunity of domestic substitution of new energy vehicles and realize the continuous extension of business strategy. It is an effective measure for the company to continuously optimize and improve product structure, further expand business scale, expand market share and add new profit growth points.
(3) The joint construction of sealing and testing production line will improve the core technical competitiveness of the company and strengthen the guarantee of supporting sealing and testing capacity of the project product line
The automotive chip industry has high technical standards, which requires long-term quality management, functional safety, information security and other standard testing and certification before it can be applied in the industrial chain. In the later production process of high-end products, by jointly building the sealing and testing production line with the sealing and testing factory, it is conducive to the technical collaborative innovation and continuous iterative optimization of the company’s power chip design and module packaging, improve the company’s core technical competitiveness in high-density power packaging, form the technical advantages of combined products of intelligent power devices, power control chips and power modules, and improve the company’s product line coverage in the target market.
The company aims to lay out high-end products in the field of automotive electronics and jointly build sealed and tested production lines, which is an important measure to consolidate and strengthen the company’s own advantages in the subsequent development stage. The project will further strengthen the guarantee of supporting sealing and testing capacity of the project product line, improve the reliability, yield and supply capacity of products, and stabilize the large-scale delivery and supply of the company.
(1) The national development plan of relevant industries provides strong policy support for the project
Under the new round of global scientific and technological revolution and industrial reform, the development mode of the automobile industry is undergoing profound changes. New energy vehicles have become an important symbol of the transformation and upgrading of the global automobile industry and one of the strategic emerging industries vigorously developed in China.

In November 2020, the manual on the supply and demand connection of automotive semiconductors issued by the Ministry of industry and information technology proposed that the Ministry of industry and information technology will actively guide and support the development of automotive semiconductor industry. At the same time, strengthen the construction of supply chain and increase the allocation of production capacity by means of automobile semiconductor supply and demand docking platform, so as to provide strong support for the stable and healthy development of the industry.
The introduction of relevant national policies has created a good environment for the healthy and rapid development of the automotive semiconductor industry.
(2) The new energy vehicle industry has gradually become a high growth track, and the project has market guarantee
The automobile industry is the pillar industry of China’s national economy. China is the world’s largest automobile producer and consumer. Due to the limited oil reserves and non renewable resources, traditional fuel vehicles can not develop sustainably. It has become a global consensus to replace fuel vehicles with new energy vehicles. New energy vehicles are an important starting point for achieving the “double carbon” goal, and have important strategic significance for ensuring national energy security and promoting social and economic development. The development plan for new energy vehicle industry (20212035) issued by the general office of the State Council proposes that by 2025, the sales volume of new Shanxi Guoxin Energy Corporation Limited(600617) vehicles in China will reach about 20% of the total sales volume of new vehicles. After 15 years of continuous efforts, the core technology of Shanxi Guoxin Energy Corporation Limited(600617) vehicles in China will reach the international advanced level, pure electric vehicles will become the mainstream of new sales vehicles, and vehicles in the public domain will be fully electrified.
Driven by policy and market, the new energy vehicle industry has gradually become a high growth track. According to the statistics of China Automobile Industry Association, the production and sales of electric vehicles in China in 2021 were 3.545 million and 3.521 million respectively, with a year-on-year increase of 1.6 times, and the market share increased to 13.4%, an increase of 8% compared with 2020, further indicating that the electric vehicle industry has shifted from policy driven to market driven. Electric vehicles perform well and flourish. As the automotive chip of the electronic control system of electric vehicles, its market demand has increased significantly. The broad market demand will provide market guarantee for the company to layout the automotive electronics field and expand product application scenarios.
