【摘要】 在现有的经济学文献中 ,对腐败问题的讨论 ,规避道德文化的思路并不能令人满意地解释实际中存在的问题。本文建立了一个关于道德腐败的模型解释腐败活动猖獗的原因 ,并根据历史上成功经验和教训给出相应的政策建议。本文认为 ,个体的社会道德观念、行为在社会中相互影响。这样就可以建立一个动态的模型解释基于道德导致腐败规模变化的原因。本文最主要的结论是 :存在着一个“道德腐败陷阱”。从这一点出发 ,本文认为 ,从根本上有效抑制腐败单靠加强执法、加大对腐败的惩罚力度等传统的、事后的打击腐败措施是不够的 ,要制定和实施综合的反腐战略 ,其中关键是要建立一个全社会的事前监督、检举腐败的从国家到公民的“信誉机制”。更多还原

【Abstract】 Owing to ignoring moral cost, the existing papers on corruption didn’t give a satisfactory explanation to the practical problem. In this paper, we construct a model to explain why corruption can be rampant. Besides, on the basis of the successful and the failing experience, we give corresponding suggestion to prevent corruption. we put forward that individual morality and behavior will interact in the society. Based on this idea, we can construct a dynamic model to explain how morality affects malversation. The most important conclusion we draw is that there exists a corrupt trap. So, in order to prevent corruption effectively, the traditional method is not enough. What is the most important is to build a credit mechanism which includes beforehand supervise and encouraging disclosure.更多还原
