长江经济带物流业高质量发展水平测度及评价

以长江经济带物流业为研究对象，采用熵值法、Dagum基尼系数分解和Kernel密度估计分析等方法，测度2010—2021年长江经济带物流业高质量发展水平并分析区域内发展差异。研究发现：长江经济带物流业高质量发展水平向好趋势明显，然而地区差异明显，呈现出下游物流业高质量发展水平较高、而中上游物流业高质量发展水平较低的格局，但区域发展差距呈现缩小趋势；具体而言，经济发展基础、物流运载能力、技术创新能力总体呈下降趋势，绿色发展成效较稳定，物流产业绩效呈波动上升态势。据此，建议加强长江经济带物流业区域间的合作，缩小其区域差距；重视物流业技术创新和基础设施建设，提升物流运输效率；大力发展绿色物流，构建区域绿色物流网络，提高材料的回收利用率。

Measurement and Evaluation of High-Quality Development Level of Logistics Industry in Yangtze River Economic Belt

Taking the logistics industry in the Yangtze River Economic Belt as the research object, this paper calculates the comprehensive index of high-quality development of the logistics industry in the Yangtze River Economic Belt from 2010 to 2021 by the adopting entropy method. It uses the Dagum Gini coefficient and the Kernel density estimation to analyze the regional differences. The results show that the high-quality development of the logistics industry in the Yangtze River Economic Belt has been improving greatly. However, the regional differences are still obvious, with the downstream logistics industry presenting a higher-quality development while the middle and upper reaches of the logistics industry show a lower-quality development. But it may be a great thing to see the narrowing gap. Specifically, the economic development foundation, logistics carrying capacity and technological innovation capability show a downward trend in general, while the logistics industry performance shows an upward trend with stablegreen development. Therefore, it is suggested to strengthen regional cooperation of logistics industry in the Yangtze River Economic Belt and to narrow regional gaps. Besides, more attention should be paid to the technology innovation in logistics industry and infrastructure construction so as to improve the efficiency of logistics and transportation. Moreover, great efforts should be made to develop green logistics and to build a regional green logistics network for better recycling and utilization rate of materials.
