| Research Abstract |
This research presents hypotheses regarding collective actions for irrigation management, with the help of evolutionary game theory, and verifies them empirically. Data for the analysis was collected by the author from the irrigation system of rural Yunnan, China. The agricultural Census was also used for the analysis of Japan. An econometric analysis reveals that collective action will be forthcoming in a rural community where few non-farm job opportunities are provided, the degree of income disparity among water users is quite small, and resource restrictions are moderately problematic. Also, the relationship between group size and collective action is ambiguously determined in our theoretical model, but there exists an inverse "U-shape" relationship. The fact that communities without local government intervention outperform those with intervention lends strong support to the frequently voiced view that governments or external agencies should delegate significant parts of the control rights of CPRs to immediate stakeholders.
