Examination of the optimum regional point system by Gift & Circulation Model

Community currencies have been used for regional revitalization in various area of Japan, however, there are problems in many cases. In this paper, we built our original Gift & Circulation Model as a regional point system and performed multi-agent simulation. Based on this data, we considered the conditions for promoting people's interaction by Difference In Difference analysis. As a result of the analysis, to make system that increasing more points for the participants, it is possible to promote people's interaction by giving points between participants.
