Abstract:

This study focuses on the policy of high-standard farmland construction and adopts the PMC index model as the research method to construct a policy evaluation framework, aiming to provide a theoretical basis and practical guidance for the continuous optimization of agricultural land resource management. The study first conducts semantic analysis and structural modeling of the policy text, and by extracting the policy keywords and constructing the keyword co-occurrence matrix combined with the social network analysis method, it finally forms a multilevel evaluation system containing 10 dimensions and 49 subdivided indicators. In the empirical link, the study selects 10 samples of high-standard farmland policies in three typical agricultural belts, namely, the Northeast Black Soil Area, the East China Plain Area and the Central Hilly Area, to carry out a comparative study of regional differentiation. By calculating the comprehensive performance index and constructing a three-dimensional policy evaluation matrix, the significant features of different policy programs in terms of implementation efficiency, coverage and sustainability are systematically identified. The results of the study concluded that the current policy system works well in terms of target synergy and implementation guarantee, and can effectively promote the construction of high-standard farmland, but there is still room for improvement in terms of the construction of dynamic adaptation mechanisms. Therefore, this paper proposes a four-pronged optimization path: first, to formulate a policy flexible adaptation mechanism to improve the response speed of technological changes in agricultural production; second, to formulate a step-by-step target system and prepare a special technology roadmap for high-standard farmland policy; third, to improve the differentiated incentive mechanism and formulate detailed incentive and constraint standards; fourthly, it will strengthen the focus of the policy, clarify the policy objectives, and increase the impact of the policy by expanding the means of regulation and clarifying the rules of implementation. This paper innovatively incorporates the PMC index model into the policy for constructing high-standard farmland, establishing a policy evaluation index system. It quantitatively evaluates, analyzes, and conducts a regional comparative study of 10 policy documents related to high-standard farmland construction. Future research should further explore the effectiveness of these policies.
