Market Structure and International Trade in Japan's Industry

This paper examines the effects of industrial concentration and other control variables on international trade in Japan's manufacturing industry for 1976-1980. The primary findings are (1) Concentration has a positive and significant impact on both export share and import share;(2) both labor intensity and subcontract ratio have a positive and significant effect on export share; (3) tariff rate has an import-preventing effect, while the relative disadvantage due to the imports of main materials has a positive and significant impact on import share.
