This paper is the sequel of Kano and Kawaguchi (2003a,b), which develop introduction of differential tariff to spatial equilibrium model of perfectly compentitive international trade under real triff quota system with specific duties and ad valorem duties, but which does not develop such a model of imperfectly compentitive international trade. In this paper, we show how to take differentiate tariff system into consideration when we try to apply the model and present a spatial equilibrium model ob international trade, which can be used as an efficient and general analytical tool of oligopolistic international trade of some type under real tariff quota system with specific deties, as valorem duties and differential tariff. We also persent simple examples of the model and solve the example problems to get equilibrium solutions. Implications of this paper and problems to be solved in the future are summarized in the last section of this paper.
