摘　　要：本文利用实验数据对公共品私人自愿提供机制的多个经典特征事实进行了实证检验,其结论基本支持诸如"公共品私人自愿供给的存在性"、"捐献率随重复捐献次数的增加而有下降的趋势"和"公共品投资的私人边际回报率和交流的正效应"等特征事实。同时,实验还得到了一些新的发现,如"期初平均捐献水平较低"、"口头协议效果显著"、"经验分享存在积极作用"和"小组的合作程度存在巨大的差异"等。这些结论说明通过合理的制度设计和安排可以达到部分公共品由私人自愿提供的目的。Based on the experimental data,this paper gives a positive analysis on the possibility of public goods being provided by private voluntary contribution.Through the statistical analysis of the experimental data,it elaborates the several traditional typical facts,such as the existence of voluntary contribution of public goods,the decline trend of contribution in repeated games,the positive effect of MPCR(marginal per capita return of public investment) and communication,etc.Besides,new findings are displayed,e.g.lower initial contribution than traditional results,better effect of oral agreements and huge heterogeneity in group behavior and so forth.The conclusion is that the goal of public goods being provided by voluntary contribution can be achieved by system design and arrangement.
