Abstract: In view of the dislocation and inconsistency between the government will and the cognition from all walks of life in the national park system construction, this paper reveals the policy orientation, objectives, and direction of the national park system construction while meticulously delineating the governance characteristics throughout this process. By employing a "tool-goal-effectiveness" policy analysis framework and merging content analysis with a Policy Matching Coefficient (PMC) index model, a quantitative evaluation is undertaken on 106 national and provincial (district) national park policy documents. Key findings include: (1) The construction of the national park system and mechanism reveals prominent stage characteristics, showing the evolution law from "concept explanation+institution introduction" to "emphasizing ecological protection+paying attention to management+strengthening construction" to "ecological protection first+overall planning+supervision and management+effectiveness evaluation". (2) National park policies predominantly employ compulsory tools, particularly evident in areas such as supervisory management and delineation of responsibilities. (3)Despite ecological protection and management system reform constituting the mainstay of national park policy objectives, there remains inadequate attention towards enhancing people′s livelihood and well-being, fostering harmonious coexistence between man and nature, and engaging in global governance. (4) The overall effectiveness of chosen national park policy texts is relatively high. However, compared to central government policies, those at local levels exhibit lower effectiveness. This can be attributed to factors including a lack of macro-guidance perspective in local policies, insufficient emphasis on law enforcement supervision and publicity, a paucity of systematic planning and institutional reform measures in the construction process, single choice of policy nature, and one-sided policy recipients. Thus, recommendations are made for the continuous refinement of national park policy texts from three aspects: multiple allocation of policy tools, improvement of policy target system, and optimization of policy effectiveness mechanism.
