Different with the research of macroscopic effect related to economic growth,the distribution of wealth and social stability,this paper combines the system of macro environment and micro enterprise decision-making,and focuses on the influence of official corruption on enterprise agency costs and the conduction mechanism.Based on China's A-share listed companies' annual data from 2000 to 2012,this paper empirically tests the influence of official corruption on enterprise agency costs.We find that official corruption significantly increases the agency costs of the enterprise.Specifically,the higher the degree of official corruption in the location of the company,the higher the enterprise fee ratio is.And enterprise asset utilization ratio is negatively correlated with official corruption.We also find that the influence of official corruption on the private enterprise agency costs is more significant compared with the state-owned enterprises,and the market-oriented reform effectively cushions the influence of official corruption on enterprise agency costs.
