The leadership of the Communist Party of China serves as the fundamental institutional guarantee for contemporary China’s high-level policy performance. Differing from the relationship between political parties and the government in Western contexts，the Communist Party of China not only as the architect of policy objectives but also as the overarching leader driving policy implementation. While existing scholarship has examined the Party’s positioning，operational mechanisms，and institutional methods in policy implementation，research on CPC leadership remains constrained by the foundational logic of the “politics-administration dichotomy”. Consequently，it has yet to emerge as a central concern within mainstream implementation theory. Comprehensive and systematic investigations remain scarce concerning critical institutional phenomena such as the leadership system，the functional responsibilities and operational processes of the CPC organizations，and the methodological mechanisms through which the CPC leads policy fulfillment. Significant explanatory limitations persist in elucidating the overall leadership of the CPC. To construct an independent public policy knowledge system of China，research should return to the empirical phenomena. A systematic research should be developed across agenda setting，theoretical frameworks，and methodologies，which will provide new research perspectives for explaining the core mechanisms of China’s successful governance.
