| 为研究数字经济对农业绿色全要素生产率的影响及其内在逻辑，在运用SBM模型和GML指数测度农业绿色全要素生产率的基础上，利用2011—2020年中国30个省份（统计数据未含西藏、港、澳、台地区，下同）的面板数据来分析数字经济对农业绿色全要素生产率的影响效应，并从土地经营效率视角考察土地集约经营效率与土地规模经营效率在数字经济影响农业绿色全要素生产率的作用机制。结果表明：1）数字经济会对农业绿色全要素生产率产生显著促进效果；2）土地集约经营效率和土地规模经营效率在数字经济影响农业绿色全要素生产率的过程中分别起显著的中介效应和遮掩效应。运用门槛效应模型发现超过门槛值后，土地集约经营效率进一步提升了数字经济对农业绿色全要素生产率的促进效果；3）数字经济对农业绿色全要素生产率的提升效果在不同区域呈现显著的异质性，东部地区的提升系数显著为0.137、秦岭—淮河线南北两侧地区的提升系数显著为0.115和0.319、胡焕庸线东南部地区的提升系数显著为0.068。这表明数字经济促进了东部地区、秦岭—淮河线两侧地区和胡焕庸线东南侧地区的农业绿色全要素生产率。本研究据此提出，在我国农业现代化建设中应当拓展数字技术应用场景，加强农业数据资源建设，积极推进适度规模的集约型农业发展。 |

| Abstract: |
| This study aimed to investigate the impact of the digital economy on agricultural green total factor productivity and its internal logic. Based on the application of the SBM model and GML index to measure agricultural green total factor productivity， a panel data from 30 provinces in China （The data do not include those of Xizang， Hong Kong， Macau， and Taiwan regions. The same below.） from 2011 to 2020 was taken to analyze the impact of the digital economy on agricultural green total factor productivity. From the perspective of land management efficiency， the mechanisms through which land intensive operation efficiency and land scale operation efficiency influence the impact of the digital economy on agricultural green total factor productivity were investigated from the perspective of land management efficiency. The results indicate that： 1） Digital economy development significantly promotes agricultural green total factor productivity. 2） The land intensive operation efficiency and land scale operation efficiency play significant mediating and masking roles， respectively， in the process of the digital economy's impacting agricultural green total factor productivity. The threshold effect model found that the land intensive operation efficiency can further promote the effect of digital economy on agricultural green total factor productivity after exceeding the threshold value. 3） The promotion effect of the digital economy on agricultural green total factor productivity exhibits significant heterogeneity across different regions. The promotion coefficients in the eastern region is 0.137， in both sides of the Qinling-Huaihe River are respectively 0.115 and 0.319， and in the southeastern part of the Hu-Huan-Yong Line is 0.068. This suggests that digital economy has promoted agricultural green total factor productivity in the eastern region， both sides of the Qinling-Huaihe River， and the southeastern part of the Hu-Huan-Yong Line. Based on above findings， this study proposes that ， the expansion of the application scenarios of digital technology， strengthening of agricultural data resource construction， and active promotion of moderately scaled intensive agricultural development are necessary in the construction of agricultural modernization in China. |
