本文通过两阶段公共品博弈测度出个体社会偏好类型，研究个体社会偏好异质类型的分布规律和社会角色影响公共品自愿供给水平的直接效应和间接效应。实验研究发现：个体社会偏好存在异质性；搭便车行为和条件性合作者的自我服务偏向是公共品自愿供给的两大特征事实，两者对于公共品自愿供给水平有着至关重要的决定性作用。分析结果表明个体社会偏好的异质类型会显著影响公共品自愿供给水平，而性别和学生干部等社会角色存在显著差异的个体异质类型分布，由此间接地影响公共品自愿供给水平。与此同时，不同的社会角色也会直接影响公共品自愿供给水平。实验分析结果证实并且揭示社会角色影响公共品自愿供给水平的直接影响效应和间接渠道效应。

Basing on the two-stage public goods experiment, this paper sheds light on the distribution of individuals＇ heterogenous preferences and the direct and indirect effects of social role on the public goods provision. The experimental results indicate that the individuals＇ decision-making behaviors in public goods are heterogeneity, and the free-riding of free-rider and self-serving bias in conditional cooperators are two typical facts in the public goods experiment, which play a crucial role ＂in the understanding of the aggregation behavior in public goods. And the results also show that different types of individuals＇ preferences have distinct effects on voluntary contribution of public goods game, while the social roles such as gender and the identity of cadres have significant effects on public goods provision, whose effects are direct and indirect that via the heterogenous preferences. These results are in favor of the theory of the direct and indirect effects of social role on public goods provision.
