China's constitutional supervision exhibits the characteristics of Chinese-style democracy, showing a strong resonance with the essential attributes of “whole-process people's democracy” in socialist democratic politics. This system reflects a harmonious coordination between democracy and the rule of law, as well as a balance between democracy and efficiency. Chinese-style democratic elements can be thoroughly explored through both the supervisory body and the supervisory process. The legitimacy of the supervisory body is primarily demonstrated through its function, institutional setup, personnel, and organizational structure, while the supervisory process largely involves the legitimacy of matters and content. The National People's Congress(NPC) and its Standing Committee exercise independent constitutional supervisory powers that aid in reinforcing the mechanism of legitimacy chains, diversifying supervisory forms, and ensuring coherence across various functions. The entities subject to constitutional supervision possess varying degrees of democratic legitimacy, necessitating appropriate adjustments in the strength of supervision according to each entity. The extraction of elements of Chinese-style democracy from the constitutional supervision system aims to advance the standardization and proceduralization of constitutional supervision under the guiding principle of Chinese-style democracy. This approach ensures that constitutional supervision remains aligned with the path of socialism with Chinese characteristics and elevates constitutional implementation to a new level by fully utilizing the advantages of the institutional framework.
