The purpose of this study is to clarify the status of resident activity in maintaining urban parks and the effectiveness of the incentives provided by the government to promote such resident activity, and to consider the way of these incentives in the future. In this study, we first carried out a questionnaire-based survey on 860 local governments. The contents of the questionnaire were the status of resident activity in maintaining urban parks, the incentives provided by the government to promote resident activity, activities and their contents and the effectiveness of these incentives. Then, we analyzed the data obtained as a result of the survey. The results are as follows: 1) We found that the incentives provided by the government to promote the resident activity and the effectiveness of these incentives are various and related. 2) We clarified the possibility and problems that the governments strategically provide incentives to promote the resident activity with the aim of forming a community based on mutual assistance.
