Abstract: Ecological environment protection and governance is an important part of national governance.Conventional governance and movement governance are the two most common mechanisms to solve the problems of ecological environment governance.Due to the failure of the conventional governance mechanism,movement governance mechanism starts and realizes the organizational goals through embedded control.Ecological performance evaluation attempts to guide and regulate the administrative behavior of local governments and officials through the routine appraisal mechanism.This kind of mechanism has the problems of principal-agent risk,conflict of central and local targets,and small incentive intensity of performance results,which easily leads to the emergence of the "collusion behavior" of the ecological environment governance among local governments,so it requires an alternative governance mechanism to achieve viable and effective governance.Therefore,environmental inspectors have emerged as the dominant mechanism to regulate the rhythm of ecological environment governance.Through embedded control,the failure of ecological performance evaluation can be effectively curbed,and the "collusion behavior"among local governments can be regulated to realize the effective control of the local government's environmental governance behavior.

Key words: ecological performance evaluation, collusion behavior, control rights, environmental supervision
