项目摘要

This research re-examines a network formation of the local communities on the Yahagi River basins, from the view point of the generalized logic of collective action, and derives the conditions both for mountain forests in the headwater area and for river water qualities in the mid and down basins to be preserved on a voluntary basis. The main results are as follows :1.Common-pools on the Yahagi-River basins have been, if not perfectly, preserved by the leadership of the Yahagi-River Social Network, which was formed by appeal for selective-incentives schemes designed for farmers and fishermen' organizations, respectively.2.River water is preserved, on a sufficient level, as the club-commons which are collective interests for privileged groups. On the other hand, mountain forests had to be preserved, on an insufficient level, as the public-commons which is collective interests for latent groups.3.The empirical and theoretical results of the above are corroborated by the questionnaires which were addressed to 400 residents in the areas. They showed that the benefits obtainable form the mountain forests are less than those from the river water.4.The questionnaires also showed that a business scheme of selective incentives-cum-collective goods such as an eco-goods scheme is more efficacious in financing for the preservation of public commons such as forests than voluntary contributions. The theoretical logic of voluntary provision of public goods could be corroborated by the questionnaires.5.Social entrepreneurs are key-players in preserving natural common-pools on the river basins on a voluntary basis, and not-for-profit organizations are preferred by them on a rational basis.We can derive from those results the policy implication that teaching programs for social entrepreneurs are required to be set up in graduate schools.

本研究从集体行动的广义逻辑的观点出发，重新审视了Yahagi河流域当地社区的网络形成，并得出了在自愿的基础上保护上游地区山林和中下游流域河流水质的条件。主要研究结果如下：1. Yahagi河流域的公共资源池在Yahagi河社会网络的领导下得到了保护，即使不是完美的保护。Yahagi河社会网络是由分别为农民和渔民组织设计的选择性激励计划的呼吁而形成的。另一方面，山林作为潜在群体的集体利益的公共共有物，其保护程度不够。3.通过对400名居民的问卷调查，验证了上述实证和理论研究结果。调查表还表明，选择性激励措施和集体商品的商业计划，如生态商品计划，在为保护森林等公共资源筹资方面比自愿捐款更有效。5.社会企业家在自愿的基础上是流域自然公共资源保护的主要参与者，他们在理性的基础上更倾向于选择非营利组织，这一结果为我们提供了政策启示，即在研究生院设立社会企业家课程。
