In order to provide reference for the further study of China-ASEAN Free Trade Area(CAFTA), the research structure and research focus are made through the quantitative analysis of the existing literatures in CAFTA. The research status of CAFTA is analyzed quantitatively through the co-word analysis of keywords, social network analysis, cluster analysis and multidimensional scale analysis. The results show that the study of CAFTA presents 4 hotspots, namely, regional economic integration, dispute settlement mechanism, trade effect, and tax coordination.
