傾向スコアマッチング法による農地・水・環境保全向上対策のインパクト評価

－北海道における共同活動支援を対象として－

抄録

The impact of measures implemented by the Ministry of Agriculture, Forestry and Fisheries on rural communities to conserve and improve land, water, and the environment is evaluated, using the difference-in-differences method with propensity score matching. The results indicate that support for community activities positively influences vitalization of village assembly and management of common-pool resources. However, the support does not have immediate effects; the activity items for management of common-pool resources increase progressively.
