In general,the ratio of the agricultural sector occupied to GDP along with economic growth decreases,and the ratio of agricultural workers to all employees decreases as well.Therefore,to maintain a sustainable agricultural sector and to realize a dynamic rural area,the demonstration of the multi-functionality of agriculture and farmland is requested,rather than merely supply agricultural products.Against such a background,in the developed countries including Japan,the policy of regional development oriented toward industrial promotion and creation of community-based business by utilizing common-pool resources where agriculture are centered has been spotlighted.However,in the existed agricultural and rural economics,agriculture and the rural sector is considered to be a passive section that adjusts the change in manufacturing and the urban sector without being located as a center section in regional development.
