新型城镇化提升了中国农业绿色全要素生产率吗？

基于2006-2017年中国30个省份的面板数据,采用基于SBM方向性距离函数的GML指数法和熵值法分别测算了中国农业绿色全要素生产率和新型城镇化水平。在此基础上,通过构建空间计量模型和面板门槛模型,探讨了新型城镇化对中国农业绿色全要素生产率影响的空间溢出效应和门槛特征。研究结果表明：新型城镇化对农业绿色全要素生产率的空间溢出效应显著,而且存在单一门槛效应。在经济发展水平跨过门槛值时,新型城镇化对农业绿色全要素生产率影响的负向效应逐渐减弱,各省份之间经济发展水平呈现出不均衡性,使得新型城镇化对农业绿色全要素生产率的影响差异性明显。

Does the New Urbanization Promote the China

Based on the panel data of 30 provinces in China from 2006 to 2017, the GML index method based on SBM directional distance function and entropy method were used to measure the China"s agriculture green total factor productivity and new urbanization level. On this basis, through the construction of spatial econometric model and panel threshold model, this paper discusses the spatial spillover effect and threshold characteristics of the impact of new urbanization on China"s agricultural green total factor productivity. The results show that: the new urbanization has a significant negative spatial spillover effect on the growth of agricultural green total factor productivity; and there is a single threshold effect. When the economic development level crosses the threshold value of 10.723, the negative effect of new urbanization on agricultural green total factor productivity gradually weakens. The level of economic development among provinces is unbalanced, which makes the impact of new urbanization on agricultural green total factor productivity significantly different.
