摘要
基于2006—2021年中国省域平衡面板数据,运用Super-SBM测度了物流业绿色转型水平(Lgtfp),借助熵值法对各省市数字经济发展指数进行了分析,检验了数字经济对Lgtfp的直接效应、中介效应与空间效应。研究发现,地区数字经济水平对Lgtfp具有显著正向作用,数字经济基础设施建设、产业数字化与数字经济发展环境对Lgtfp的促进作用尤为明显,相对于中西部地区,东部地区Lgtfp的提升受数字经济的影响更大;就影响机制而言,物流业产业结构升级发挥积极的中介效应;进一步的空间计量分析表明,数字经济对Lgtfp存在显著的正向空间溢出效应,不仅会促进本地区Lgtfp的提升,还有助于邻近地区Lgtfp的提高。研究为促进数字经济发展和推动物流业绿色转型提供了政策参考。
Based on the provincial balance panel data of China from 2006 to 2021,this paper uses Super-SBM to measure the green transformation level(Lgtfp)of logistics industry,and analyzes the digital economy development index of each province and city with the help of entropy,and examines the direct,intermediate and spatial effects of digital economy on Lgtfp.It is found that the regional digital economy level has a significant positive effect on Lgtfp,and the digital economy infrastructure construction,industrial digitalization and digital economy development environment have a particularly significant promoting effect on Lgtfp.Compared with the central and western regions,the promotion of Lgtfp in the eastern region is more influenced by the digital economy.As far as the influence mechanism is concerned,the upgrading of logistics industrial structure plays a positive intermediary effect;Further spatial econometric analysis shows that the digital economy has a significant positive spatial spillover effect on Lgtfp,which will not only promote the increase of Lgtfp in the region,but also contribute to the increase of Lgtfp in neighboring regions.The research provides policy reference for promoting the development of digital economy and promoting the green transformation of logistics industry.
