【摘要】 研究目的：科学探究乡村数字化转型对耕地绿色利用效率的影响机制，为推进乡村数字化转型赋能耕地绿色生产提供理论依据。研究方法：非期望产出SBM模型，Tobit回归模型和面板门槛回归模型。研究结果：(1)中国耕地绿色利用率均值由2011年0.628上升至2021年0.845，年均增幅2.17%，空间上呈现“东部、西部、中部”和“粮食主销区、产销平衡区、粮食主产区”依次递减格局；(2)乡村数字化转型水平均值由2011年0.127增长至2021年0.259，年均增幅10.49%，空间上呈现“东部、中部、西部”和“粮食主销区、粮食主产区、产销平衡区”依次递减非均衡格局；(3)中国乡村数字化转型对耕地绿色利用效率具有显著促进作用且存在区域异质性，东、中部地区乡村数字化转型的促进作用较西部地区更为显著，粮食主产区和产销平衡区较粮食主销区更为显著；(4)乡村数字化转型水平越过门槛值0.261时，对耕地绿色利用效率促进作用呈现边际效应递减的单门槛非线性特征。研究结论：区域间应联通数字赋能耕地绿色利用的合作共享网络、扩大数字技术对耕地利用环境污染的缓释效应和衔接耕地利用主体数字化耕种需求，是实现耕地绿色利用的长效驱动路径。更多还原

【Abstract】 The purpose of this study is to scientifically explore the influencing mechanism of rural digital transformation on cultivated land green use efficiency,to provide the theoretical basis for promoting rural digital transformation and empowering green production of cultivated land.The research methods include unexpected output SBM model,Tobit regression model and panel threshold regression model.The results indicate that:1) the average green use rate of cultivated land in China increased from 0.628 in 2011 to 0.845 in 2021,with an average annual growth rate of 2.17%.The spatial pattern showed a decreasing order of “eastern,western,and central” and “main grain sales areas,production and sales balance areas,and main grain production areas”.2) The average level of rural digital transformation increased from 0.127 in 2011 to 0.259 in 2021,with an average annual growth rate of 10.49%.In terms of space,a decreasing and unbalanced pattern of “eastern,central,and western” and “main grain sales areas,main grain production areas,and production sales balance areas” occurred.3) The digital transformation of rural areas in China had a significant promoting effect on improving cultivated land green use efficiency,showing regional heterogeneity.The promoting effect of rural digital transformation in the eastern and central regions was more significant than that in the western regions,and the main grain producing areas and production sales balance areas were more significant than the main grain sale areas.4) As the level of rural digital transformation exceeded the threshold value of 0.261,the promotion effect on cultivated land green use efficiency showed a single threshold non-linear characteristic of diminishing marginal effects.In conclusion,the long-term driving path to achieve cultivated land green use is to establish a collaborative sharing network that empowers digital technology for cultivated land green use among regions,expand the mitigating effect of digital technology on environmental pollution in cultivated land use,and connect the digital cultivation needs of cultivated land use entities.更多还原
