This paper analyzed changes of trade structure among Korea and East Asia countries and their deteminants for the period 1976-2004.
Nine East Asia countries were classified into three groups according to their income level : Japan, Newly Industrializing Economies 3 Countries(NIEs 3) and Developing Countries 5(DC 5).
Industries were classified 22 on the basis of OECD's ISIC and reclassfied 4 groups as their technology levels.
The empirical results were as follows : First, Korean NEX(Net Export Index) was consistently negative for Japan, but positive for NIEs 3 and DC 5 for the period.
Intra-industry trade index has increased for all groups, especially for DC 5. Next, While the comparative disadvantage of inter-industry trade in high technology industries was decreased for Japan, the comparative advantage in high and low technology industries for DC 5 was also decreased.
Third, Korea is consistently dependent on the Japan at the middle-high technology industries including general machinery and scientific instruments.
So does china for the Korea. Fourth, Inter-industry trade structure between Korea and Japan, Korea and NIE's 3 hadn't a similarity, but Inter-industry trade structure between Korea and Japan, Korea and DC 5 had been a opposite tendency since middle 1990s.
Interestingly Intra-industry trade structure between Korea and Japan, Korea and DC 5 has been a similar tendency since middle 1990s. Finally, changes of trade structure among Korea and each East-Asia country were determined according to differences in production specilization pattern and trade structure variables.
