Abstract: The leadership of the Communist Party of China is not only the essential requirement of socialism, but also the only way to promote the modernization of China's ecological governance. The paradigm of "state-society" originating from the West cannot provide scientific guidance for China's ecological governance, and it is in a state of loss of voice at both the macro and micro levels. By analyzing the generation logic of China's ecological governance modernization driven by political parties, it is found that the gene of the leading party, adaptive party, and mission-oriented party of the Communist Party of China is the embodiment of legitimacy logic, reality logic, and organizational logic. The need for a beautiful and ecological living environment, ecological governance effectiveness, and mission responsibility consciousness from the perspectives of gravity, pressure, and inner force constitute the driving mechanism of the Communist Party of China leading China's ecological governance modernization. In specific response strategies, the party's organizational system, decision-making and execution model, and integration mechanism are used to build a composite ecological participation network, reshape the government's ecological governance capacity, and optimize the allocation of ecological governance resources, thereby achieving synergy among the party, state, and society at the level of ecological governance.
