With the continuous escalation of Sino-US trade frictions, the crackdown of the United States in the field of science and technology against China is becoming more and more serious. The United States not only takes export control measures on high-tech exports to China, but also imposes tariff restrictions on high-tech products imported from China. An in-depth study on the import and export trade characteristics of China's high-tech products was made. The results show that the import and export structure of China's high-tech products is relatively single. The trade gravity model was used to make an empirical analysis of the factors that affect the import and export of high-tech products in China. The results show that the improvement of national innovation and opening-up can promote the export of high-tech products. Increasing the export of high-tech products will help to change the status quo that China is large but not strong in foreign trade and enhance its position in the global value chain.
