长江经济带物流高质量发展效率测度及影响因素研究

Study on the Measurement of Efficiency and Influencing Factors of High-quality Development of Logistics in the Yangtze River Economic Belt

文中采用三阶段DEA模型测度长江经济带11省市2012-2021年物流业高质量发展效率,并借助Tobit回归探究其影响因素。研究显示:①长江经济带物流业高质量发展效率随时间推移总体呈上升趋势,且整体上呈“下游—中游—上游”递减的趋势。②经济发展和交通建设会显著影响效率值的测度,总体上使效率值有所提升。③经济发展和信息化水平的提高会促进物流业高质量发展,城镇化水平则对其存在负向影响。

This paper uses the three-stage DEA model to measure the high-quality development efficiency of logistics industry in 11 provinces and cities along the Yangtze River Economic Belt from 2012 to 2021,and explores the influencing factors by using Tobit regression.The research shows that:①The logistics efficiency integrally increases over time,and decreases with the trend of“downstream—midstream—upstream”.②Economic development and traffic construction will significantly influence the measurement of the efficiency,which generally improve the efficiency.③Economic development and informatization level will increase the efficiency,while the urbanization is vice versa.
