This thesis analyzed the export structure and competitive relation of Eastern Asia after the economic crisis in 1997. After the crisis, the export of Eastern Asia slowed down; especially the economic stagnation of Eastern Asia resulted in the big scale decrease in export in that area. Under this situation, Eastern Asia began more and more depending on the export of America. The competition among the Eastern Asia countries takes on a fiercer situation in American market. On the other hand, observing the export competition among the Eastern Asia countries in American market around the foreign exchange crisis period in aspects such as the market share, the extent of export competition and the index of MCA, the result is that Korea has fallen behind the other countries of Asia including China. The export-oriented economy of Korea has been pinned down. Especially considering the importance of export after foreign exchange crisis, this will be a disconcerting problem.
