摘　　要： 在一个标准的公共品自愿供给实验环境中,本文借助实验经济学方法研究了通过初始禀赋不平等、个体投资公共品边际收益不平等和出场费不平等3种方式体现的收入不平等与社会偏好、公共品自愿供给之间的相互关系。实验主要得出以下结论:一是公共品自愿供给是可能的,不过在多期重复中明显下降;二是初始禀赋不平等、个体投资公共品边际收益不平等都会对个体公共品投资行为产生显著影响,而出场费不平等的影响则不确定;三是个体公共品投资行为主要可由互惠和不平等厌恶理论所解释。这些结论对于我们全面理解收入不平等、社会偏好和公共品自愿供给三者之间的关系,特别是公共政策的设计具有重要意义。 In a standard experiment of the voluntary provision of public goods(VPOPG),in this paper,we have used the method of experimental economics to study the relationship,embodied by the initial endowment inequality,the inequality of the marginal income of the public goods of the individual investment,between the income inequality,the social preference and the VPOPG..By our experiment,we have drawn the following conclusions:(1) the VPOPG is possible,but it drops obviously in many repetitions,(2) both the initial endowment inequality and the equality of the marginal income of the public goods of the individual investment will produce noticeable impact on the investment behavior in the individual public goods,but the effect of show-up inequality is not sure,(3) the behavior of the public goods investment can be mainly explained by the theory of reciprocity and inequality aversion.These conclusions are of great significance to our comprehensive understanding of the relationship between the income inequality,the social preference and the VPOPG,especially to the design of public policies.
