A Consideration on Independent Urban Area Formation in National Capital Region Development Program

National capital region has acted as a Japanese leading role through the current of various times from the war damage rehabilitation to the present. National Capital Region Development Program was projected five times as a readjustment in the National capital region. These projects were aiming to prevent the over-concentration of urban functions in Tokyo. But it is said that over-concentration of urban function in Tokyo has not been solved yet. So the purpose in this research is to clarify whether the distributive policy is truly proper or not for National Capital Region Development Program. First, we build up a hypothesis that the amount of production in National capital region varies according to the formation of Independence Urban Area. Secondly, defining Independence Urban Area, we aim to confirm the relationship among several areas by analyzing the amount of monetary transference and production. If Independent Urban Area was to set up and the number of employee dispersed from the central business district, we might draw a conclusion of changing the whole amount of production in National capital region. By this analysis we can verify our hypothesis.
