Abstract

Based on an analysis of the International Input-Output Table Japan-Korea (1985, 1990) and the Asian International Input-Output Table (1995), this paper focuses on changes in import dependency structure of intermediate products between Korea and Japan after the Plaza Accord, an agreement which triggered a drastic appreciation of the yen. Considering the industrial structures of the two countries and the structure of the trade between them, special attention was paid to the manufacturing sectors, which were analyzed on the basis of a more detailed industrial classification than the other sectors. In particular, we measured the technological international specialization (TIS) index between Korea and Japan, which provided a foundation for studying the structure of Koreas heavy dependence on Japan-made intermediate inputs. The TIS index shows the amount of intermediate goods certain industries in two countries import from each other, and serves as a good indicator of a country's dependency on imports for intermediate inputs. / The empirical results showed that Korea still depends quite heavily on imported intermediate inputs from Japan, particularly in the machinery industry. The results also showed clearly that Japan is gradually becoming more dependent on Korean-made intermediate inputs. / This implies that the technology gap between Korea and Japan has gradually narrowed throughout the sample period.
