Abstract: The filing and review mechanism for intra-Party normative documents is a crucial component of the intra-Party supervision system.It provides robust organizational and institutional support to promote the supervision of policy-making powers within the Party,as well as the organization,institutionalization,and standardization of filing and review work,thereby enhancing the quality of intra-party normative document formulation.The organizational structure of this mechanism exhibits a "unitary multi-layered" characteristic.On the one hand,the leadership system of the Party exerts a unifying influence over the filing and review mechanism,with central-level filing and review authority guiding local-level authorities,thus forming a unitary organizational structure.On the other hand,the filing and review authority is systematically divided into central,provincial,municipal,and county levels,creating a hierarchical organizational structure.Through the integration of governance mechanisms,responsibility mechanisms,procedural mechanisms,and incentive mechanisms,the filing and review mechanism constructs an effective operational framework.Regulatory legitimacy,normative legitimacy,and cognitive legitimacy together provide a comprehensive framework for understanding and interpreting the institutional legitimacy of the filing and review mechanism.The establishment of this mechanism reflects three intertwined institutional logics:the structural logic that unifies the whole with its parts,the systemic logic that harmonizes vertical and horizontal dimensions,and the governance logic that aligns authoritative mechanisms with effective governance.

Key words: intra-Party normative documents, filing and review mechanism, intra-Party supervision system, organizational structure
