This paper explores the impacts of exchange rate on trade between Japan and China, with special attention to differences of pricing structure of international trade across
industries. Although the Chinese yuan was fixed against the U.S. dollar for several years, it has been fluctuating against the Japanese yen, which provides us with a natural
experiment to test the exchange rate effect. We find that exchange rate changes and volatility have little influence on trade volume in most industries, while Chinese economic growth significantly affects Japans export to China. For electrical machinery industry, in which Japanese firms division of production process is prevailing, we find no evidence of exchange rate impact on trade. These results suggest that the recent reform on Chinas exchange rate system does not seem to have a significant effect on the external sectors of the two countries and the cost of exchange rate fluctuation can be, to some extent, mitigated by Japanese firms overseas production and pricing structure.
