数字经济对农业绿色全要素生产率的影响OA北大核心CSTPCD

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.
