Abstract
All local municipalities in various parts of Japan have been given the legal authority to establish an effective organizational structure in order to enhance their local autonomous status. In this regard, various consolidation plans have been proposed. However, in many cases, it appears that the process have not been progressing smoothly as originally expected. Against this premise, by using the revised versions of famous indices of voting game, “The Shapley Shubik index” and “The Banzhaf index”, this paper aims to investigate on how the two specific factors, namely, population and geographical consolidation process affect the major problem confronting the Japanese local governments.
