我国农业绿色全要素生产率的测度及其影响因素研究

Study on the measurement of green total factor productivity and its influencing factors in China's agriculture

在资源要素投入以及环境污染的非期望产出基础上分析我国农业绿色全要素生产率的特征及其影响因素,以期为我国农业效率的客观评价和农业可持续发展提供技术支撑,促进我国农业现代化进程中资源、环境和经济三者的协调发展。通过实证分析,得出以下主要结论:(1)从各地区的技术缺口比率TGR值来看,我国整体上农业生产效率的技术缺口比率平均值为0.602,且这一缺口呈现扩大趋势。(2)从空间相关性来看,31个省市的MML指数、MEC指数和MTC指数大多数通过了显著性检验,存在全局空间自相关;在σ收敛分析中可以看出2004-2015年我国农业绿色全要素生产率呈现波动上升的趋势,且我国农业绿色全要素生产率存在绝对β收敛以及条件β收敛。并提出以下政策建议:(1)推进农业产业绿色协调发展;(2)重视农业技术研发和推广;(3)建立健全绿色监管体系;(4)转变农业补贴方式。

This paper analyzes the characteristics of agricultural green total factor productivity and its influencing factors on the basis of resource input and environmental pollution,with a view to China＇s agricultural efficiency of the objective evaluation and sustainable development of agriculture to provide technical support to promote China＇s agricultural modernization process of resources,environment and the coordinated development of the three. Through the empirical analysis,the following main conclusions are drawn：（1）In terms of the technical gap ratio TGR of each region,the average gap ratio of agricultural production efficiency in China is 0.602,this gap shows an increasing trend.（2）The MML index,MEC index and MTC index of 31 provinces and cities in China have passed the significant test,which means there exits global spatial autocorrelation; in theσconvergence analysis,it can be seen that the total green factor productivity of agriculture in China is increasing from 2004 to 2015,and there is absoluteβconvergence and conditionβconvergence in China＇s agricultural green total factor productivity. This paper proposes the following policy recommendations：（1） strengthen the regional cooperation of agricultural green development;（2） change the way of agricultural subsidies;（3） attach importance to research and promotion of agricultural technology（4） establish and improve the pollution supervision system.
