物流产业集聚对区域经济增长的空间溢出效应研究——基于长三角城市群的实证分析

On the spatial spillover effect of logistics industry agglomeration on regional economic growth:Based on the empirical analysis of the Yangtze River Delta urban agglomeration

以长三角城市群27个市2010—2018年的面板数据为样本,探讨物流产业集聚对区域经济增长的影响机制,运用区位熵测度其物流产业集聚水平;通过ESDA方法测度和研究其经济增长空间相关性、空间集聚性和空间异质性,并以空间计量模型检验物流产业集聚对经济增长的空间溢出效应。研究结果表明:长三角城市群物流产业集聚具有明显的空间非均衡性,区域经济增长的空间自相关性显著,物流产业集聚对群内各市的经济增长起到显著促进作用,同时对其邻市具有正向空间溢出作用。应从合理引导布局、深化开放和匹配效应等方面优化长三角城市群物流产业的空间布局,进而提升其区域经济增长竞争力。

This study,by taking the 27 cities from 2010 to 2018 in the Yangtze River Delta urban agglomeration as samples,first explores the mechanism of logistics industry agglomeration on regional economic growth,and exploits location entropy to measure the level of the industry agglomeration,and then,by employing the ESDA method,measures and studies the spatial correlation,agglomeration and heterogeneity of its economic growth,and tests the spatial spillover effect of the logistics industry agglomeration on economic growth through the spatial measurement model.The results show that the logistics industry agglomeration in the Yangtze River Delta has significantly spatial imbalance,and that the regional economic growth shows significant spatial autocorrelation.Besides,the logistics industry agglomeration plays a significant role in promoting the economic growth of the cities in the group,and exerts a positive spatial spillover effect on its neighboring cities.Finally,the spatial layout of the logistics industry in the Yangtze River Delta urban agglomeration should be optimized from the perspectives of reasonably guiding the layout,deepening the opening up,and promoting multiplier effect so as to enhance its the competitiveness of regional economic growth.
