The Dilemma and Optimization Path of Cross-Border Data Flow Under the Background of Digital Economy and Trade

In the context of the digital economy and trade, China, the United States and Europe have formed a three-pole pattern of global digital economy development. Cross-border data flow is a necessary condition for the balanced development of economic globalization and information technology globalization. However, due to the difference in value orientation among the three, no unified rules for cross-border data flow have been reached internationally, and the cross-border flow of data is still fragmented, which is not conducive to the development of the digital economy and trade. By exploring the specific cross-border data models of various countries, this paper analyzes the problems existing in the cross-border flow of data in the digital economy. It puts forward a scheme suitable for our country to optimize the cross-border flow of data by improving the domestic data flow trading market, actively participating in international data cross-border related agreements, establishing an international data cross-border flow mechanism, and promoting the development of the digital economy and trade.
