Abstract: Purpose/Significance At present, our government is facing the transformation from traditional administration to ecological administration. The so-called ecological administration refers to the government's behavior of maintaining ecological balance, ensuring ecological security and realizing ecological benefits by adhering to the administrative concept of giving priority to ecological benefits, constructing a multi-co-governance ecological governance system in accordance with relevant laws and regulations. Design/Methodology From the perspective of system science, this paper analyzes the power source that affects the local government's ecological administration system, and constructs the local government's ecological administration power mechanism. Findings/Conclusion At present, the dynamic mechanism of ecological administration of local governments in China is confronted with the realistic dilemma of weak ecological awareness, weak political pressure, insufficient collaborative governance and low efficiency of information transmission. By correcting the value mechanism, strengthening the restriction mechanism, optimizing the cooperation mechanism, and improving the communication mechanism, we will promote the development of ecological administration of local governments in China.
