As one of the most important achievements in the construction of Asian-Pacific regional economic integration in recent years,the development process of RCEP has attracted widespread attention.This study takes the core paper data on RCEP collected by the CNKI database from October 2012 to March 2023 as the research sample,and uses CiteSpace to analyze the cooperation of authors and institutions,research hotspots,and evolutionary trends.The results show that the domestic academic community pays high attention to the RCEP process,and the output of research has grown rapidly.The RCEP research has gone through three stages:the germination stage,the exploratory stage,and the growth stage,focusing on key and difficult issues,mainly focusing on comparative analysis of RCEP with TPP and CPTPP,country-specific studies of RCEP,impact studies of RCEP and quantitative studies of RCEP.In the future,RCEP research should focus on improving the depth of macro policy research and paying attention to micro application research.
