数字经济对绿色物流发展的影响机制及区域差异研究

Research on the Impact Mechanism and Regional Differences of Digital Economy on the Development of Green Logistics

基于2010—2021年中国30个省份面板数据,通过熵值法计算数字经济发展水平,构建固定效应模型和中介效应模型,从数字经济视角出发探究影响绿色物流发展的作用机制。研究结果表明,数字经济显著促进绿色物流发展,同时表现出明显区域差异,东部地区数字经济对绿色物流的影响在5%水平上显著,中部地区在1%水平上显著,而西部地区不显著;中介效应检验结果表明,数字经济可通过刺激技术创新、推动产业结构升级、提高绿色配送效率来促进绿色物流发展。

Based on panel data of 30 provinces in China from 2010 to 2021,the development level of the digital economy was calculated by using the entropy method,and a fixed effect model and a mediation effect model were constructed to explore the mechanisms that affect green logistics development from the digital economy perspective.The research results show that the digital economy significantly promotes green logistics and exhibit significant regional differences.The impact of the digital economy on green logistics is significant at the 5%level in the eastern region,significant at the 1%level in the central region,and not significant in the western region.The test results of mediation effect indicate that the digital economy promotes the development of green logistics by stimulating technological innovation,pushing industrial structure upgrading,and improving green distribution efficiency.
