The Study About Gini Coefficient Model Using Public Facility Data

摘要

Nowadays the regional gaps between the metropolitan area and the local areas in Japan have expanded. We can also guess the importance of this problem from the situation which ―Headquarters for Overcoming Population Decline and Vitalizing Local Economy‖ has been established in the Cabinet and various efforts for that have been made. Gini coefficients have often been used when the regional gaps are analyzed but, in many cases, the Gini coefficients focus on incomes of people. Then we have developed a new model of Gini coefficients which focuses on the number of public facilities to analyze the regional gaps from the viewpoint of public infrastructure. Thus it has turned out to be no regional gap from the viewpoint of public infrastructure around principal stations as a result of the analysis conducted on the basis of the data concerning the number of public facilities around principal stations of 47 prefectures by using the model.
