Abstract: The combination of trade protectionism and the digital revolution has promoted the innovation of the global system, accelerated the reconstruction of the digital governance framework, and digital economic and trade rules have become the core elements to break through the barriers of traditional rules and realize the leap of welfare. Based on the regional economic and trade agreements, this paper constructs a rule system framework covering five categories of topics and 57 sub fields, including e-commerce and digital trade, data flow, new data economy, cross cutting issues and intellectual property rights. This paper empirically tests the welfare effect differences of 70 economies from 2007 to 2022 by using double and triple difference model. The results show that the welfare utility level of the agreement member states has significantly improved, highlighting the “rule dividend”; the depth of rules presents the ladder characteristics of “Asia Pacific template>American template>European template”. The promotion of member states' welfare by different depth agreements is heterogeneous, and the high depth agreements increase their welfare by 8.1%. The Asia Pacific template is increasingly forward-looking in the new economic field. In the face of external shocks such as changes in the international situation, China should actively promote the deepening of digital economic and trade rules and shape a diversified digital cooperation network to break the “rule containment” of the United States and the west, enable the high-quality development of digital economy and trade with institutional openness, and build a new pattern of digital economic and trade rules with rising welfare.

Key words: Reconstruction of Digital Economic and Trade Rules, Depth of Digital Trade Rules, Welfare Level, Rule Dividend
