Based on the new economic geography (NEG) theory, we analyzed the determinants of location choice for Japanese frozen food industry investments in East Asia. A location choice model of Japanese frozen food industries with domestic market potential, supplier access, sufficient raw materials, investment promotion policies of host countries, and traditional factors such as wages and infrastructures as explanatory variables was estimated. First, we estimated the trade equation of Redding and Venables (2004). Therefore, domestic market potential of the country is defined by the relative real GDP of domestic and trade partners including the following two effects, trade costs subjected to time distances between the exporter and the importer, and existence or non-existence of free trade agreements (FTA・EPA) with other countries. Supplier access of the country is also defined by relative food or agricultural goods price of export goods. In this paper, we focused on the effects of domestic market potential, supplier access of raw materials (agricultural goods) and investment promotion policies. The conditional logistic model, showed that domestic market potential, supplier access of raw materials and investment promotion policies of host countries as well as traditional cost reduction factors such as wages and infrastructures affect the location choice for Japanese frozen food industry investments in East Asia.
