Empirical Analysis of Deterministic Factors of Intra-Industry Trade of Korea' Trade with Japan

This paper aims to measure the level of intra-industry trade(IIT) by using Korea-Japan trade and macroeconomic data from 1991 to 2008 and on the basis of this result analyzes the determinants of the intra-industry trade. By using the Newey-West estimation method to overcome the shortcomings of OLS and kernel regression methods we draw the following conclusions: First, the portion of vertical intra-industry trade(VIIT) within IIT is very high. This reflects the change and stream of Korea⋅Japan's income difference as it is the pattern appearing at the trade between the countries having different income levels. Second, high quality vertical intra-industry trade(HQVIIT) within VIIT is very high. This is different from the theory that home country exports low quality products in the case that trade partner's income level is higher than home country's, vice versa. Third, only the variable, "the difference between two countries market sizes", among the determinants of all three types of IIT, affects positively all three types of IIT.
