企业腐败动机与“最优”腐败程度实证研究

对于企业向官员行贿动机的解释主要有两种相反的观点，一是企业为了获取政府帮助而主动行贿，二是企业在威胁逼迫条件下的被动行贿。文章从企业在应对政府和应对市场两项事务间的权衡出发，构建企业绩效与腐败强度间的二项式回归模型，通过与传统线性回归模型的比较，发现企业腐败是一种主动行为，腐败的目的是为了构建政治关系以获取相应回报。运用世界银行企业调查数据，二次项回归模型显示出绩效与腐败强度间显著的倒U型曲线关系，文章得出了企业的“最优”腐败程度并对其政策含义进行了解释。

The Motivation of Firm Corruption and the "Optimal" Corruption Level

Because of the linear hypothesis, existing literature have not got an agreement conclusion on the relationship between corruption and business performance. Some scholar’s research shows that there is positive between corruption and business performance, but on the other hand, Some scholar’s research shows that there is negative between corruption and business performance. The conflict between the two empirical view shows the academic understanding of firm corruption is different by scholars. This paper study the relationship between corruption and business performance based on the Weigh options between deal with government and deal with market by firms, and build a quadratic regression model to investigate the “optimal” degree of dealing with government. We use the world bank’s enterprise survey data confirmed the reverse u relationship between corruption and business performance.
