摘要：

基于“绿水青山就是金山银山”理念，探讨省以下环保垂直管理改革对农业生态产品价值转化效率的影响。利用2012—2022年中国30个省份面板数据，运用双重机器学习模型进行实证检验。结果显示，环保垂改显著提升了生态产品价值转化效率，且结论经过多重稳健性检验后依然稳健；机制分析发现，环保垂改主要通过改善环境质量与推动生态农业两条路径促进效率提升；异质性分析表明，该效应在市场化程度低、环保重视度高以及政府环境审计强度大的地区更为显著。建议进一步深化省级环境管理协同机制，优化绿色要素配置体系，并针对不同地区实施差异化的生态治理政策，以持续提升生态产品价值转化能力。

Abstract：

Based on the concept that “lucid waters and lush mountains are invaluable assets”, this study explores the impact of vertical environmental management reform below the provincial level on the efficiency of agricultural ecological product value conversion. Using panel data from 30 provinces in China from 2012 to 2022, a dual machine learning model was employed for empirical testing. The results show that the vertical environmental management reform significantly improves the efficiency of ecological product value conversion, and the conclusion remains robust after multiple robustness tests. Mechanism analysis reveals that the reform primarily enhances efficiency through two pathways: improving environmental quality and promoting ecological agriculture. Heterogeneity analysis indicates that this effect is more pronounced in regions with lower marketization levels, higher environmental awareness, and stronger government environmental audits. It is recommended to further deepen the provincial environmental management coordination mechanism, optimize the green factor allocation system, and implement differentiated ecological governance policies for different regions to continuously enhance the capacity for ecological product value conversion.
