At present, the total amount of digital trade in Shanghai is increasing but the growth rate is slowing down. Building the rules of digital trade with high standards can provide opportunity and stimulus for the development of digital trade in Shanghai. Based on this，this paper  constructs the framework of digital trade rules based on the content of digital trade clauses in representative regional trade agreements，analyzes the characteristics and shortcomings of policies and measures implemented in Shanghai in the process of connecting digital trade rules，and finds that：Shanghai is actively linking rules and provisions in the areas of digital trade facilitation，international cooperation and regulation，and digital trade innovation，but exploring rules and provisions in the areas of reducing digital trade barriers，enhancing  consumer confidence，and network access and security is relatively less. Based on this put forward targeted policy suggestions.
