电商减贫的物流调节效应研究——基于地级市的数据

Research on Logistics Moderating Effect of E-commerce Poverty Reduction: Based on the Data of Prefecture-level Cities

本文选取2007-2017年全国285个地级市的面板数据,构建电商减贫的物流调节效应模型,采用层级回归方法对物流调节效应进行实证分析。实证结果表明:电商对减贫有显著的正向影响;从全国层面来看,物流能显著地正向调节电商减贫效应;从分地区结果来看,物流对电商减贫效应的调节作用存在空间异质性,在东部地区物流也能显著地正向调节电商减贫效应,中部地区正向调节效应仍然显著,但其系数明显低于东部,而在西部地区则不显著。

Based on the panel data of 285 prefecture-level cities in China from 2007 to 2017,this paper constructs the logistics regulation effect model of e-commerce poverty reduction,and makes an empirical analysis of logistics moderating effect by hierarchical regression method.The empirical results show that e-commerce has a significant positive impact on poverty reduction;at the national level,logistics can significantly and positively regulate the poverty reduction effect of e-commerce;from the regional results,there is spatial heterogeneity in the regulation of e-commerce poverty reduction effect,logistics can also significantly positively regulate the poverty reduction effect of e-commerce in the eastern region,the positive adjustment effect in the central region is still significant,but its coefficient is obviously lower than that in the east.In the western region,however,the effect is not significant.
