The integrated circuit is the most technologically advanced and value-added field in the electronic information industry，and it is also a segmented area difficult to catch-up in terms of technology. From the perspective of the entire industry chain，the United States is in a leading position，Japan，South Korea，and China’s Tai Wan are in the second group，however with a large gap between them and the United States. Europe has monopoly power in some segments. China is an important player of the global IC industry. Both China and the United States are important import and export countries of IC in the world. China has a huge deficit with the United States，and bilateral trade has shown a downward trend in recent years. Sino-US trade friction has impacted China’s IC industry from three aspects：First，the United States restricts China’s imports through trade protection policies while supporting related industries in other developing countries. Secondly，the United States has used patents，standards，and other irregular means to hinder China’s enterprises from independent technology research and development，global factor layout and global market expansion，seriously undermining China’s catch-up pace. Thirdly，by restricting technology transfer and export of core components and high-end equipment，the United States has left China a generation’s gap to catch up with，therefore badly hindering the transformation and upgrading of China’s integrated circuit industry.
