Notice of Retraction: The Coalmine Manager's Safety Work Behavior in Optimal Incentive Model

Abstract

In order to reveal major factors constraining China's coalmine safety, the principal-agent relationship in China coalmine management is analyzed, a multi-task incentive model is constructed by setting different functions of production and performance, the coalmine manager's work behavior under optimal incentive contracts is analyzed and some meaningful conclusions are obtained. It is concluded that: it is actually an indirect principal-agent relationship that China government supervises coalmine manager; The effort level on work of coalmine manager decrease along with the risk level of work increasing, but increase along with the coefficient of effort-performance increasing. It is the underlying reason for heavy production, light safety that the risk lever of coalmine work is higher and the coefficient of effort-performance is lower. To urge coalmine manager improve the performance, it needs to take some outside measures.
