Abstract: The quantitative research on the trade effects of digital trade rules is urgently needed with the continuous development of digital trade rules under the framework of regional trade agreements.Based on the panel data of bilateral digital export trade of 40 countries (or regions) around the world to all their trading partners from 2005 to 2019,this paper has acquired the following findings.Firstly,the digital trade rules under the framework of regional trade agreements have a significantly positive impact on the digital service export trade of the contracting parties.The smaller the gap of the digital infrastructure and the regulatory level between the contracting parties,the greater the export promoting effect.Signing digital trade rules will promote the growth of digital service export trade by lowering digital trade barriers between the contracting parties.Secondly,whether it is trade-promotion-related clauses,data-related clauses,or privacy protection clauses,they all reflect a stronger promoting effect on digital service export trade.Thirdly,the European template and other templates have all shown a positive promoting effect on digital service export,while the American template has shown an inhibitory effect.Lastly,digital trade rules have also shown a significant promoting effect on the export of digital goods,especially the export of information and communication-technology products.

Key words: digital trade rules, digital service export, digital infrastructure, digital trade barriers
