摘要
在分析数字技术对国家级物流枢纽城市集货效率影响机理的基础上,选取中国20个国家级物流枢纽城市2011-2021年的面板数据测算数字技术发展综合指数和城市集货效率水平及其区域差异,进一步实证检验了前者对后者的影响程度及区域异质性。结果显示,数字技术显著提升了国家级物流枢纽城市的集货效率。异质性分析发现,数字技术对城市集货效率的影响在中部城市和二线城市更为显著,这或许与它们还处于边际收益递增阶段有关。基于以上结果,提出加快数字技术健康发展以驱动国家级物流枢纽城市集货效率提升的全国总体性及区域差异性等对策建议。
Based on the analysis of the impact mechanism of digital technology on the cargo consolidation efficiency of national logistics hub cities,the panel data of 20 national logistics hub cities in China from 2011-2021 are selected to calculate the comprehensive index of digital technology development,the level of urban cargo consolidation efficiency and its regional differences,and further empirically test the impact of the former on the latter and regional heterogeneity.The results show that digital technology has significantly improved the efficiency of cargo consolidation in national logistics hub cities.Heterogeneity analysis found that the impact of digital technology on urban consolidation efficiency is more significant in central and second tier cities,which may be related to their still in the stage of increasing marginal returns.Based on the above results,suggestions are proposed to accelerate the healthy development of digital technology to drive the improvement of cargo consolidation efficiency in national logistics hub cities,including national and regional differences.
