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，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，digital trade innovation，but exploring rules and provisions in the areas of reducing digital trade barriers，enhancing consumer confidence，network access and security is relatively less. Accordingly，it is necessary to consolidate the foundation for the development of the digital industry and realize the benign interaction between rules and industries；establish a sound cross-border data flow system；connect key issues in international digital trade rules as soon as possible；form digital trade intellectual property protection and services that benchmark against the highest international standards system；open government data，improve data innovation and application capabilities.
