中文摘要：

在中国经济和社会转型的背景下，市场化和城镇化进程共同构成影响社会信任的重要宏观制度环境。基于市场化、城镇化与社会信任的关系机理，使用世界价值观调查（WVS）的中国数据，采用宏观和微观相结合的方法，探讨了市场化和城镇化进程对个体社会信任的影响。实证结果发现：市场化进程对个体社会信任具有显著的促进效应。就现阶段而言，城镇化程度与社会信任度呈负相关关系，城镇人口和流动人口规模的扩大、地区治安水平的下降对社会信任带来一定程度的负面影响。随着城镇化程度及其质量的提升，市场化进程对社会信任的促进效应将得到增强。

英文摘要：

In the process of China＇s economic and social transition, marketization and urbani- zation are the two main macro factors which affect social trust. Based on the relationship among marketization, urbanization and social trust, and by using China data of World Values Survey （ WVS）, an empirical research is made to explore the impacts of marketization and urbanization on individual social trust. Empirical results show that marketization exerts a positive and statistically significant influence on individual social trust. At present, urbanization has a negative effect on social trust. The expansion of urban residents and mobile population, and the decrease of regional public security bring negative influence on social trust. With the improvement of urbanization de- gree and quality, the positive effect of marketization on social trust will be strengthened.
