This report takes the global semiconductor industry as the background and analyzes the current development status of the domestic semiconductor industry. From the supply side and demand side, we explore the current development status, problems and challenges of the domestic semiconductor industry, and put forward our outlook on future development. Through interviews and surveys with companies in the upstream and downstream of the industrial chain, and combined with relevant statistical data, it is found that the domestic semiconductor industry still faces problems such as imperfect industrial chain, low product quality, insufficient innovation ability, weak corporate profitability and weak competitiveness. The report finally puts forward development suggestions, including increasing infrastructure construction, promoting the coordinated development of upstream and downstream enterprises, strengthening technology innovation and R&D capacity building, supporting the development of small and medium-sized enterprises, and creating a good market environment.
