农村金融发展与农业绿色全要素生产率提升研究

Rural Financial Development and the Improvement of Agricultural Green Total Factor Productivity

乡村振兴战略背景下,农业的绿色发展和可持续发展至关重要,农村金融在这一过程中发挥着重要的支撑作用,本文主要研究农村金融发展是如何影响农业绿色全要素生产率的.基于2000-2015年中国省级面板数据,采用非径向性方向距离函数和共同前沿方法测度了农业绿色全要素生产率(GTFP)及其分解因素,然后采用动态空间面板模型进行实证检验.研究结果显示:农业绿色全要素生产率在不同区域和不同时间段呈现出不同特征,并具有显著的空间自相关性.农村金融发展规模的增加、金融发展结构的优化以及金融发展效率的提高均有利于农业GTFP提升,但其作用机制却存在显著差异.具体来看,增加金融发展规模主要是通过促进农业技术进步和缩小技术差距来提升农业GTFP;优化金融发展结构可以通过改善技术效率、促进技术进步和缩小技术差距来提升农业GTFP;提高金融发展效率主要是通过改善技术效率和促进技术进步来提升农业GTFP.在此基础上,从农村金融发展视角提出了提升农业绿色全要素生产率的相关政策建议.

Under the background of the Rural Revitalization Strategy,the green and sustainable development of agriculture is of great importance,and rural finance plays an important supporting role in this process.In this paper,we mainly study how rural finance development affects the agricultural green total factor productivity.Based on China’s provincial panel data from 2000 to 2015,this paper uses the non-radial direction distance function and meta-frontier method to measure the agricultural green total factor productivity and its decomposition,and then applies the dynamic spatial panel model in the following empirical analysis.The results show that,overall,the GTFP presents different characteristics corresponding to the different regions and different time phases,and have significant spatial autocorrelation.The increase in the scale of rural financial development,the optimization of the structure of rural financial development and the improvement of the efficiency of rural financial development are all conducive to the promotion of GTFP,but our results also suggest that there are differences among the mechanisms.Specifically,increasing the scale of rural financial development is mainly to promote the agricultural GTFP through promoting agricultural technological progress and narrowing the technological gap;optimizing the rural financial development structure can promote the agricultural GTFP through improving technological efficiency,promoting technical progress and narrowing the technological gap;improving the efficiency of rural financial development can promote the agricultural GTFP through improving technological efficiency and promoting technological progress.On this base,we put forward some relevant policy recommendations for improving the agricultural GTFP from the perspective of rural financial development.
