农机跨区作业发展对农业绿色全要素生产率的影响——基于空间溢出效应视角

The impacts of cross-region operation of agricultural machine development on the agricultural green total factor productivity:From the perspective of the spatial spillover effects

探讨农机跨区作业发展对农业绿色全要素生产率的影响,有助于为实现农业生产绿色转型的总目标提供重要的参考借鉴。基于2010—2020年30省数据,运用SBM—GML模型测算农业绿色全要素生产率,进一步构建空间杜宾模型实证分析农机跨区作业发展对其影响。结果表明:1)农机跨区作业面积和农业绿色全要素生产率呈现波动变化态势,且二者均存在空间自相关关系。2)农机跨区作业发展对农业绿色全要素生产率有显著的提升作用,且存在正向空间溢出效应,农机跨区作业发展每提升1%,农业绿色全要素生产率提升0.993%,其中本地上升0.175%,邻近地区上升0.819%。3)在东部、中部、粮食主产区和粮食主销区,直接效应不显著,空间溢出效应显著;在西部地区和粮食产销平衡区的各效应均显著。因此,应当鼓励引导发展农机跨区作业服务,实现区域内“农机共享”;因地制宜选择农机跨区服务发展模式,提升区域资源配置优化;提升农机跨区作业管理效率,维护农机跨区作业秩序。

Discussing the impacts of the cross-region operation of agricultural machinery development on agricultural green total factor productivity(AGTFP)provides an essential reference for realizing the general goal of green transformation of agricultural production.Based on a data of 30 provinces from 2010 to 2020,this paper evaluated the agricultural green total factor productivity by the SBM-GML model,and empirically analyzed the impacts of the cross-region operation of agricultural machinery development by the spatial Durbin model.Results show that:1)crossregion operation of agricultural machinery and agricultural green total factor productivity show fluctuating changes,and both have spatial autocorrelations;2)cross-region operation of agricultural machinery development has a significant promotion effect on the agricultural green total factor productivity,and there is a positive spatial spillover effect;for every 1%increase in cross-region operation of agricultural machinery development,the agricultural green total factor productivity will be increased by 0.993%,with a local increase of 0.175%,and other areas increase of 0.819%;and 3)In the eastern regions,central regions,main grain-producing regions,and main grain-marketing areas,the direct effect is insignificant while the spatial spillover effect is significant;in the western regions,the balance of grain production and marketing area,both effects are significant.Therefore,it is vital to encourage and guide the development of cross-region operation services for agricultural machinery,to achieve“sharing of agricultural machinery”within the region;to choose the development mode of cross-region operation services for agricultural machinery according to local conditions,to enhance the optimization of regional resource allocation;to enhance the efficiency of the management of cross-region operation for agricultural machinery,and to maintain the order of cross-area operation for agricultural machinery.
