Research on the Impact of COVID-19 Epidemic and Sino-US Trade War on Global Industrial Chain

China, as the largest export trade country in the world, is in the middle and low end of the global industrial chain, and is vulnerable to the impact of the global industrial chain. This paper analyzes the causes of Sino-US trade war from four aspects, and studies China's export dependence, status and external demand in the global industrial chain. At the same time, combined with the special background of COVID-19 epidemic, this paper analyzes its impact on the global industrial chain. This paper holds that China, facing the dual background of Sino-US trade war and COVID-19 epidemic, should seek innovative development, actively promote multilateral cooperation, insist on seeking common ground while reserving differences in development, and at the same time strengthen supply-side reform.
