公务员腐败的一个重要原因是我国目前的制度安排尚有缺陷,导致腐败成为“高收益低风险”行为。从微观经济学理论出发,建立成本——收益模型和公务员腐败——廉洁选择的决策树模型。通过制度创新,使腐败成为被查处概率极高、政治风险极大和经济成本极巨的行为。同时,提高公务员廉洁收益。 An important reason for the corruption of civil servants is that the current institutional arrangements in our country are still flawed, causing corruption to become “high-yield and low-risk” behavior. Based on the theory of microeconomics, a decision tree model of cost-benefit model and corruption-clean selection of civil servants is established. Through institutional innovation, corruption has become an act of extremely high probability of being investigated, a great political risk and a huge economic cost. At the same time, improve the honest income of civil servants.
