摘　　要：农机社会化服务对于推动粮食绿色生产和建设现代化农业体系有着重要意义。基于2010—2020年全国30个省份的面板数据,多维度构建了农机社会化服务水平的指标体系,并运用SBM-undesirable模型测算了粮食绿色生产效率,通过空间杜宾模型实证分析了农机社会化服务对粮食绿色生产效率的空间溢出效应、作用机制及溢出边界。研究表明,在时序维度,2010—2020年粮食绿色生产效率呈现出稳步上升趋势;在空间维度,各省粮食绿色生产效率的连片集聚程度不断加强。农机社会化服务能够促进本地区粮食绿色生产效率的提升,并对邻近地区发挥正向溢出作用;且农机社会化服务能够通过农地规模经营和农村金融等途径的交互影响来实现粮食绿色生产效率的提升。农机社会化服务对粮食绿色生产效率空间溢出的有效距离为600 km,超出此范围后会受限于地理距离而不再显著。鉴于此,应稳步提升农机社会化服务水平,完善区域间协调协作机制,推动农地规模化经营,提升农村金融发展水平。The socialized service of agricultural machinery is of great significance for promoting green food production and building a modern agricultural system.Based on the panel data of 30 provinces in China from 2010 to 2020,a multi-dimensional indicator system of agricultural machinery socialized service level was constructed,and the SBM undesirable model was used to measure the green production efficiency of grain.The spatial Dubin model was used to empirically analyze the spatial spillover effect,mechanism and boundary of agricultural machinery socialized service on the green production efficiency of grain.The research shows that in the time series dimension,the green production efficiency of grain shows a steady upward trend from 2010 to 2020.In the spatial dimension,the degree of agglomeration of grain green production efficiency in each province has been continuously strengthened.The socialized service of agricultural machinery can promote the green production efficiency of grain in this region,and play a positive spillover role to neighboring areas.Moreover,the socialized service of agricultural machinery can realize the improvement of green production efficiency of grain through the interaction of agricultural land scale operation and rural finance.The effective distance of the spatial spillover of agricultural machinery socialized services to the green production efficiency of grain is 600 km,beyond which it will be limited by the geographical distance and no longer significant.In view of this,we should steadily improve the socialized service level of agricultural machinery,improve the coordination and cooperation mechanism between regions,promote the large-scale operation of agricultural land,and improve the level of rural financial development.
