Affected by the new crown epidemic and the Sino-US trade war, the development of China's integrated circuit industry chain has been extremely bumpy due to the dual impact of insufficient upstream supply and declining downstream demand. This section first analyzes the current situation from three aspects: the policy system and institutional environment of the integrated circuit industry, the level of knowledge and technology, and the industry situation of the industry chain . An analysis was carried out to explore the research hotspots and key research directions of China's integrated circuit industry.
