土地流转和社会化服务对农业全要素生产率的影响实证分析

Impact of Land Circulation and Agricultural Socialized Service on Agricultural Total Factor Productivity

文章基于2010—2021年中国30个省份面板数据,采用SBM模型和空间计量模型实证探究了规模经营视角下土地流转和农业社会化服务对农业全要素生产率的影响、空间溢出效应及其交互效应。研究发现:(1)2010—2021年,全国层面和省级层面农业全要素生产率均呈现增长态势。(2)土地流转和农业社会化服务均能显著促进农业全要素生产率提升,且两者交互项系数显著为正,在效率提升过程中是“相得益彰”的共赢关系。(3)土地流转和农业社会化服务均具有显著正向空间溢出效应,能够促进邻近地区农业全要素生产率提升。据此,提出要推动农业社会化服务体系和土地流转体系协同联动发展,充分发挥好农业规模经营的正向空间溢出效应,共同促进农业生产提质增效。

Based on the panel data of 30 provincial-level regions of China from 2010 to2021,this paper uses the SBM model and spatial econometric model to empirically study the impacts of land circulation and agricultural socialized services on agricultural total factor productivity,their spatial spillover effects and interaction effects under the perspective of scale operation.It is found that:1)Agricultural total factor productivity showed an increasing trend at both the national and provincial levels from 2010 to 2021.2)Land circulation and agricultural socialized services both can significantly promote agricultural total factor productivity,and the coefficients of the interaction terms of the two are significantly positive,which is a win-win relationship that complements each other in the process of efficiency improvement.3)Land circulation and agricultural socialized services both have significant positive spatial spillover effects,which can promote the total factor productivity of agriculture in neighboring areas.Therefore,land circulation and agricultural socialized services are parallel and not contradictory,to promote agricultural socialized services system and land circulation system synergistic linkage development,give full play to the positive spatial spillover effects of large-scale agricultural operations,and promote the quality and efficiency of agricultural production.
