【摘要】 利用1998-2015年省份面板数据,将空间杜宾模型和偏微分效应分解方法相结合,研究了农业全要素生产率的时空演变规律、空间溢出效应及其成因。结果表明,全国区域农业全要素生产率水平不断提高,且东、中、西部三大区域差异明显,存在明显空间相关性;农村人力资本对本地区农业全要素生产率具有正向促进作用,但溢出效应并不明显,农村基础设施对本地区和邻近地区的农业全要素生产率均有正向溢出效应;而在其它影响因素中,自然环境的直接效应和间接溢出效应为负,种植结构调整系数直接效应为负,但空间溢出效应则不显著。更多还原

【Abstract】 Based on the provincial panel data of 1998-2015 and the super-efficiency DEA method to measure agricultural total factor productivity, the spatial-temporal evolution law, spatial spillover effect and its causes of agricultural total factor productivity were studied by combining the spatial Durbin model with the partial differential effect decomposition method. The results show that the level of total factor productivity of agriculture in the whole country has been improving continuously, and there are obvious spatial correlations among the three regions: east, middle and west. Rural human capital has a positive effect on total factor productivity of agriculture in the region, but the spillover effect is not obvious. Rural infrastructure has a positive spillover effect on total factor productivity of agriculture in the region and adjacent areas. Among other factors, the direct and indirect spillover effects of natural environment are negative, while the direct effect of plant structure adjustment coefficient is negative, but the spatial spillover effect is not significant.更多还原
