Simulations for Gift Circulation Model of Relationality Assets toward Rebuilding Community

摘要

Japan is now facing serious problems such as rapid depopulation and a super-aging society. Therefore, it is indispensable to rebuild a local community in Japan. In this study, we model a community as a system composed of humans, "Mono" and "Koto" as its elements, and their relationality. In Japanese, "Mono" denotes tangible and physically perceived thing/entity, and "Koto" denotes intangible and cognitively conceived thing/entity. Focusing on the importance of relationality, we have introduced the concept of relationality assets and proposed the Gift & Circulation model as a mechanism to circulate relationality assets in a community. In this study, by using System Dynamics and Multi-Agent Simulation, we evaluated how the model works and what effect the model has on the community. After that, we introduced relationality assets to the field experiment.
