Domestic substitution develops indigenous semiconductor capabilities, reducing foreign technology dependence. Efforts span research through commercialization, requiring investment, talent, and ecosystem building. Within the framework of the federal standard, "Network and System Administration" direction is. Export controls operate through entity lists, technology licensing requirements, and end-use restrictions. EDA controls focus on advanced nodes, particularly software for chips at 14nm and. In recent years, “domestic substitution” has evolved beyond a temporary slogan during supply chain tensions, becoming a deeply ingrained strategic consideration in industries like coatings, inks, and adhesives. China has been focusing on replacing computer equipment, and the telecom and financial sectors are likely to be the next targets. China has stepped up. In recent years, countries such as the United States have attempted to restrict the advanced chip manufacturing capabilities of the Chinese mainland, shifting from limiting the export of advanced semiconductor equipment to the Chinese mainland over the past few years to including multiple domestic. The domestic substitution of the IC (the Integrated Circuit) industry improves economic efficiency and is significant in ensuring national security, which has gradually become an essential strategy for countries worldwide.
