合作与不合作——农村社区公共品供给中的多重均衡

Cooperation and Non-cooperation:Multiple Equilibria in the Supply of Rural Community Public Goods

本文在农户能力异质性的背景下,通过引入社会荣辱感,研究发展中国家的农村社区公共品的不合作问题。研究发现:(1)社区凝聚力缺失导致的人们对于社会荣辱感的在意程度下降,是导致社区公共品合作参数序列狭小的重要原因。(2)合作有利于减小异质性,培育社区凝聚力,从而有利于合作,这是一个正反馈;不合作的负反馈也存在。社会调查的实证资料证实了我们的理论推测。对于当前中国面临的如何在商业化与人口流动背景下培育、重建社区凝聚力问题,文章结合日本的经验,认为需要政府发挥作用来培育农民相互协助的社会合作。

This paper discusses the reason why there are cooperation and noncooperation in the supply of rural community public goods,based on the foundation of heterogeneity and in the perspective of having or no social capital.We argues the non-cooperation in the today China's supply of rural community public goods is because that commerce and market development destroy the social capital and intensify the heterogeneity in the community,and which minishes the parameter series which the cooperative equilibrium is feasible on.But the foster of newly social capital isn't be enforced successfully.At the same time,the heterogeneity deduced by non-cooperation of farmers can be intensified in the commerce and market development.This heterogeneity makes the cooperation more difficult.It is the same that the cooperative equilibrium is also a self-enforcement one.Then,we argue we must foster social cooperation and economic cooperation for the farmers in China.
