Born in the context of digitalization, digital trade is an emerging trade model, which is based on digital technology and transformed through the digitization of trade methods or trade objects.Digital trade in solving the time and space limitations at the same time also led to the emergence of digital trade barriers, which has become a major obstacle in the process of economic globalization. Reducing digital trade barriers and promoting the synergistic development of the global digital economy are of great significance to optimizing the global value chain and enhancing the efficiency of international trade. Focusing on the relationship between digital trade barriers and global value chains, relevant theoretical models were built based on previous research, the development trend of China's digital trade under the background of "anti-globalization" was discussed, and corresponding countermeasures are put forward to address these issues.
