电商示范县政策赋能农业全要素生产率提升:政策效应、机制检验与异质性分析OACHSSCD

Agricultural total factor productivity(ATFP)is a key indicator for assessing agricultural production efficiency and the quality of economic growth.Examining the impact and mechanisms of the E-commerce Demonstration County Policy on ATFP contributes to policy optimization and the high-quality agricultural development.This study employs the SFA-Malmquist index method to measure the ATFP of 669 counties across 27 provinces from 2009 to 2021,and constructs a multi-period DID model to evaluate the policy's effects.The results indicate that the policy significantly enhances ATFP,and this conclusion remains robust after a series of validity checks;Mechanism analysis shows that the policy primarily promotes ATFP through three channels:improving information infrastructure,optimizing industrial structure,and enhancing labor allocation;Heterogeneity analysis further reveals that the policy effects are more pronounced in central regions,counties without Taobao villages,non-poverty-alleviated counties,and non-revolutionary base counties,demonstrating the differentiated impacts of the policy under varying county-level conditions.Based on these findings,it is recommended to enhance policy effectiveness from four aspects:implementing targeted measures to improve policy adaptability,deepening the integration of e-commerce and the agricultural industry,strengthening the cultivation of rural e-commerce talent,and continuously optimizing rural e-commerce ecosystem,so as to better leverage the driving role of e-commerce in agricultural modernization and rural revitalization.
