In recent years, major economies have devoted themselves to building a digital trade rule system that represents their own demands. Various economies have differentiated positions on such topics as cross-border data flow, digital intellectual property rights, non-discriminatory treatment of digital products, and digital taxes. The construction of digital trade rules is represented by China, the United States, and the European Union. However, in the context of this game, the parties have the possibility of rules convergence on the following topics: (1) Under the premise of considering the regulatory requirements of each economy, valuing and allowing the cross-border transfer of data; (2) In the field of digital intellectual property rights, promising unforced technology transfer and network intermediary liability exemptions, and protecting the source code under the premise of retaining critical infrastructure exceptions; (3) Constructing a“non-discriminatory treatment”for digital products while considering exceptions such as regulatory requirements; (4) Committing to a limited period of“duty-free electronic transmission”and improving the terms of the collection of digital service tax.
