乡村产业数字化对AGTFP的影响研究

The Impact of Rural Industrial Digitalization on AGTFP

摘要: 本文探究乡村产业数字化对农业绿色全要素生产率(AGTFP)的影响。首先采用熵权-TOPSIS、SBM-GML 模型分别测算数字化水平与AGTFP；经Hausman检验，建立固定效应模型；检验技术效率的中介效应、数字化的门槛效应，并开展异质性分析与Bootstrap稳健性检验。结果表明：(1) 数字化通过技术效率间接影响AGTFP；(2) 存在单门槛效应，低数字化阶段正向影响在1%水平显著，高阶段仅10%水平显著；(3) 影响存在区域异质性，中西部显著，东南沿海与北部地区较弱。(4) 在对AGTFP的影响作用中，数字化存在显著正向的空间溢出效应，受灾面积存在显著负向的空间溢出效应。

Abstract: This study examines the impact of rural industrial digitalization on Agricultural Green Total Factor Productivity (AGTFP). The levels of digitalization and AGTFP are measured using the entropy weight-TOPSIS method and the SBM-GML model, respectively. Based on the Hausman test, a fixed-effects model is established. The mediating effect of technical efficiency, the threshold effect of digitalization, heterogeneity analysis, and Bootstrap robustness tests are conducted. The results indicate that: (1) Digitalization indirectly affects AGTFP through technical efficiency; (2) A single threshold effect exists, with a significant positive impact at the 1% level in the low digitalization stage, but only at the 10% level in the high stage; (3) The impact shows regional heterogeneity, being significant in central and western regions but weaker in southeastern coastal and northern regions; (4) Digitalization exhibits a significant positive spatial spillover effect on AGTFP, while the disaster-affected area shows a significant negative spatial spillover effect.
