Outline of Final Research Achievements

For Kaso area (the area where the population is declining and aging) to be sustainable, it is essential to establish an economic foundation and a welfare service supply foundation. Based on this, our research project aimed at "a large regional circulation centered on a small local community".
We grasped the problem from two perspectives: the socio-economic effects of energy local production for local consumption, and the possibility of providing integrated services by mobile service providers. Specifically, the former focused on a small-scale energy production business that uses biomass (local production for local consumption), and the latter focused on the possibility of a taxi company or a postal collection and delivery business to travel between settlements during the main business. We developed a quantitative method to evaluate the feasibility and evaluated it through a case study.

Academic Significance and Societal Importance of the Research Achievements

地方の小規模な地域であっても、資源の利用の仕方によっては持続性を高める地域づくりが可能である。バイオマス利活用を例にとった小規模な地産地消エネルギー事業では、単体事業収支がかなわなくても、地域内外への波及を考慮することで地域の収支（域際収支）を改善し、地域持続への貢献へとつながることもあり得る。サービス業という経営資源においては、一つの巡回型業者が複数のタイプのサービスを供給することでその可能性を見出せる。
