Does religion matter to corruption? Evidence from China

- Religion, as an informal institution and social culture, is significantly negatively associated with regional corruption.
- The negative association between religion and corruption is weaker in provinces with stronger legal institutions.
- Anti-corruption effects of native religions are more prominent than foreign religions, and Buddhism is the most effective.

There is a growing interest in understanding how religion affects corruption. Using provincial-level panel data from 1998 to 2009, this paper investigates the effect of religious beliefs on bureaucratic corruption in China. The empirical results show that, bureaucratic corruption is negatively associated with local religious heritage, implying that religious culture plays a positive role in restraining official's corruption since religion has influence on political preference and work ethic. We also find that the negative association between religion and corruption is weaker in provinces with stronger law enforcement, which identifies the substitution effect between religious ethic and legal supervision in curbing corruption. Our findings also reveal that, among the different religions, the anti-corruption effects of China's native religions (i.e., Taoism and Buddhism) are more significant than those of foreign religions (i.e., Christianity and Islam). These conclusions are consistent and robust to various measures of main variables and a variety of robustness checks. Given the very few studies and limited data resources in the context of China, this paper as a tentative study provides new evidences of the relationship between religion and corruption.
