长三角城市群物流业效率时空演化和影响因素

Spatial-Temporal Evolution and Influencing Factors of Logistics Efficiency in the Urban Agglomeration of the Yangtze River Delta

文章选用2008—2022年长三角城市群26个城市物流业面板数据,使用DEA-Malmquist模型测度各城市物流业效率,分析其时空演化机制,并通过空间计量模型探究物流业效率的影响因素和空间溢出效应。研究结果表明:样本期内物流业效率总体呈波动上升趋势,空间自相关性日益显著;经济密度、零售贸易业发展对物流业效率具有显著提升作用,对物流产业集聚程度则呈制约作用;溢出效应方面,物流业效率具有显著正向空间溢出效应,工业化进程和政府干预也能正向带动相邻地区物流业效率提升。研究结论可为长三角城市群及其他地区物流业高质量发展提供一定理论依据和政策参考。

This essay selects panel data on the logistics from 26 cities in the Yangtze River Delta urban agglomeration from 2008 to 2022.Utilizing the DEA-Malmquist model,it measures the efficiency logistics in each city,analyzes its spatial-temporal evolution mechanism,and explores the determinants and spatial spillover effects of logistics efficiency through a spatial econometric model.Research findings:During the sample period,the overall logistics efficiency showed a fluctuating upward trend,with spatial autocorrelation becoming increasingly significant.Economic density and the development of the retail trade had a significant positive impact on the efficiency of the logistics,while they constrained the degree of logistics agglomeration.In terms of spillover effects,the logistics efficiency had a significant positive spatial spillover effect.The industrialization process and the extent of government intervention could also positively drive the efficient development of the logistics in neighboring regions.The research conclusions can provide a certain theoretical basis and policy reference for the high-quality development of the logistics in the Yangtze River Delta urban agglomeration and other regions.
