Abstract
This report describes joint public welfare institution projects for constructing buffer greenbelts to separate residential and industrial areas to control industrial pollution during the period of rapid economic growth. The effects of financial support given to municipalities by the national government in the projects were analyzed by comparing the financial structures with those of projects of constructing city parks. The investigation showed that the common welfare facility system reduced the expenses of local municipalities (rate of local burden) to a half or less of the sum paid by the municipalities in the city park construction projects. The initial construction expenses (rate of municipality's money) were also 1/5 to 1/3 of those in the city park projects, suggesting that the common welfare facility projects effectively supported the finances of local municiaplities.
