中文摘要：

通过收集中国31个省（直辖市、自治区）2001--2013年的数据，实证检验了制度环境对社会捐赠水平的作用机理。研究结果表明，制度环境对社会捐赠水平具有显著影响，在制度环境越强区域，社会捐赠水平越高；制度环境中经济环境、法律环境以及地方政府管制对社会捐赠水平具有显著正向影响，社会信任同样对社会捐赠水平具有显著影响，但其影响受到其他三个因素的调节；在程度上，地方政府管制对社会捐赠水平的影响最大，法律环境、经济环境次之，而社会信任相对较小。本文认为，地方政府为促进区域经济发展，往往致力于经济环境、法律环境的改善和社会信任体系的维护，社会捐赠水平的提升在某种意义上是上述行为的“溢出”效应。因此，地方政府欲进一步动员慈善资源，提升社会捐赠水平，最为关键的是放松对慈善组织的管制，拓展慈善组织的发展空间和捐赠者的选择空间。

英文摘要：

By collecting China＇s 31 provincial data from 2001 to 2013, this paper empirically tests the mechanism of action of institutional environment on charitable donation. The results show that the institutional environment has a significant impact on charitable donation, the stronger the institutional environment in the region, the higher the level of charitable donation. Among the several aspects of institutional environment, economic environment, legal environ- ment and local government regulation have significant positive impact on charitable donation, social trust also has a significant impact on charitable donation, but its impact is regulated by the other three factors. To some extent, local government regulation has the strongest impact on charitable donation, followed by legal environment and economic environment, while social trust relatively has little impact on charitable donation. This paper argues that in order to promote regional economic development, the local government is committed to the improvement of legal environment and economic environment and the maintenance of social trust system, the promotion of charitable donation in some sense is the ＂spillover effect＂ of such acts. Therefore, to further mobilize the charity resources and enhance the level of charitable donation, the most critical thing for the local government is to relax restrictions on charity organizations, so as to expand charity organization＇s development space and donor＇s selection space.
