Abstract
This study investigates the changing process of the urban system of Taiwan under Japanese colonization. As for the location of central managerial function, some cities like Taipei, Keelung, and Kaohsiung grew as the administrative and economic points under the rule of the government-general. And among these cities, Taipei strengthened its overwhelming superiority by the 1940s. The railway network was constructed along main cities mentioned above, and we can see the development of these cities by the analysis of the railway revenue. Judging from these, we can say that the urban system of Taiwan, including the growth of cities, was completely under the influence of the Japanese colinial policy.
