农业保险促进了农业绿色生产率提高吗

农业保险是促进农业发展由过度依赖资源消耗向绿色可持续发展转变的重要手段。本文通过构建2001-2015年全国31个省份的农业投入产出与污染排放面板数据,利用GML指数方法对农业绿色生产率进行测算并将其分解为绿色技术进步和绿色技术效率,然后运用系统GMM估计方法实证检验了农业保险对农业绿色生产率的影响。主要结论有：农业保险对农业绿色技术进步有显著的促进作用;农业保险对农业绿色技术效率有显著的抑制作用。农业保险对绿色技术进步的促进大于其对绿色技术效率的抑制作用,从而使得其对农业绿色生产率呈现显著的促进作用。

Does Agricultural Insurance Promote The Improvement of Agricultural Green Productivity in China

Agricultural insurance is an important means to promote the transformation of agricultural development from over reliance on resource consumption to green and sustainable development. The article constructs a panel data of agricultural input-output and polluting emission in 31 provinces of the whole country from 2001 to 2015, calculates green productivity of agriculture using GML index and decomposes it into green technical change and green technical efficiency, then empirically tests the influencing mechanism of agricultural insurance on green productivity of agriculture with system GMM. The main conclusions are as follows:agricultural insurance plays a significant role in promoting green technical change of agriculture while it has a significant inhibitory effect on green technical efficiency of agriculture. The promoting impact of agricultural insurance on green technical change of agriculture is larger than the inhibitory impact of agricultural insurance on green technical efficiency of agriculture, which makes it significantly promote green productivity of agriculture.
