数字普惠金融与农业产业升级--来自柯布道格拉斯生产函数的证据

Digital Inclusive Finance and Agricultural Industry Upgrading--Evidence from the Cobb Douglas Production Function

利用柯布道格拉斯生产函数构造农业现代化视角下的农业产业升级指标,构建数字普惠金融对农业产业升级的实证模型,采用全国31个省级区域2011—2018年的面板数据,使用固定效应模型,从区域视角回归分析了数字普惠金融对农业产业升级的影响。研究结果表明:数字普惠金融能有效支持农业产业升级;产业结构合理化水平的异质性使数字普惠金融对农业产业升级的促进效果不同;利用农村互联网普及率作为工具变量,可以消除模型中存在的内生性问题。

This paper constructed agricultural industry upgrading indicators from the perspective of agricultural modernization by using the Cobb Douglas production function,and constructed an empirical model of the effect of digital inclusive finance on agricultural industry upgrading.Using panel data from 2011 to 2018 in 31 provincial regions in China and the fixed-effects models,it analyzes the impact of digital inclusive finance on the upgrading of agricultural industry from a regional perspective.The research results show that:digital inclusive finance can effectively support the upgrading of agricultural industry;the heterogeneity of the rationalization level of the industrial structure results in that the promoting effects of digital inclusive finance on agricultural industry upgrading are different;the use of Internet popularization rate in rural areas as an instrumental variable can eliminate the endogenous problems of the model.
