ABSTRACT

This paper constructed an economic integration index that indicates the degree of economic integration among South Korea, Japan, and China. First, the paper presented the concept of how the three countries formed the integration, and classified it into eleven stages. Second, after dividing the concepts into institutional and relational integration, this paper reclassified the relational integration into interaction and convergence, and then selected sixteen variables. Third, after controlling all variables, they were converted into the scores used in the economic integration index by the normalization using the maximum values, which were conceptually determined. Fourth, the paper inferred on how the degree of economic integration was changed over time based on the indexes. The main results showed how the economic integration index, which consists of sixteen variables, showed a steady decline from 2010 to 2017, and the index that was composed of twelve variables, continued to increase from 2001 to 2009, while decreasing from 2009 to 2017. Even though the degree of economic integration in 2017 was higher than in 2001 due to these fluctuations, the difference was not much.
