| Outline of Final Research Achievements |
A major characteristic of Japanese agricultural landownership is that farmers own small, geographically scattered plots. To improve productivity and maintain or enhance agricultural production capacity, farmland consolidation is necessary.
Considering the above, this research quantitatively examined by simulation the extent to which plot exchange can consolidate fragmented farmland. Specifically, we propose a collective, centralized approach, based on the top trading cycle algorithm. Also, this research aimed to evaluate the economic impact of agricultural policy such as the irrigation and drainage project, the Conservation Policy of the Land, Water and Environment. Spatial durbin model suggested that the irrigation and drainage project had impacted rural communities by increasing the ratio of area rent-in. And difference in differences estimation indicated that the Conservation Policy of the Land, Water and Environment maintained the common resources in rural communities.
