农业保险对我国农业全要素生产率的动态影响——基于中国2007-2018年省级面板数据的实证研究

The Dynamic Impact of Agricultural Insurance on China s Agricultural Total Factor Productivity——Based on China s Provincial Panel Data from 2007 to 2018

农业全要素生产率是农业经济增长的源泉,普及农业保险是提升农业全要素生产率的重要抓手.只有深入探寻农业保险不同层次水平对农业全要素生产率不同程度的影响,才能精准发挥农业保险对现代农业高质量发展的助推作用.该文基于2007-2018年的省级面板数据,运用固定效应模型,探究不同发展阶段农业保险对农业全要素生产率的动态影响.研究表明:①农业保险能显著促进农业全要素生产率的增长,且在东部地区促进效果强于其他地区;②在农业保险发展的高级阶段,农业保险对农业全要素生产率的促进作用明显高于初级阶段和中级阶段;③在农业保险发展的初级阶段,农业保险主要通过提高技术效率促进农业全要素生产率,在中、高级阶段则主要通过提高技术进步推动农业全要素生产率.

Agricultural total factor productivity is the source of agricultural economic growth.Popularizing agricultural insurance is an important way to improve agricultural total factor productivity.Only exploring the different effects of different levels of agricultural insurance on agricultural total factor productivity can accurately give agricultural insurance to play the role on promoting the high-quality development of modern agriculture.Based on the provincial panel data from 2007 to 2018,this paper uses the fixed effect model to explore the dynamic impact of agricultural insurance on agricultural total factor productivity in different stages of agricultural insurance development.The results show that:①Agricultural insurance can significantly promote the growth of agricultural total factor productivity,and the promotion effect in the eastern region is stronger than that in other regions;②In the advanced stage of agricultural insurance development,the promotion effect of agricultural insurance on agricultural total factor productivity is obviously higher than that in the primary and intermediate stages;③In the primary stage of agricultural insurance development,agricultural insurance mainly promotes agricultural total factor productivity by improving technical efficiency,while in the middle and advanced stages,agricultural insurance mainly promotes agricultural total factor productivity by improving technical progress.
