摘要:为促进商贸物流高质量发展与区域协调,选取53个商贸服务型国家物流枢纽承载城市为研究样本城市,基于53个样本城市2014—2022年的面板数据,构建包含经济发展水平、商贸发展水平、基础设施水平、物流发展水平、人才信息潜力等5个维度的商贸服务型国家物流枢纽承载城市评价指标体系,采用熵权-逼近理想解排序(technique for order preference by similarity to ideal solution,TOPSIS)法计算样本城市的综合发展水平得分,构建耦合协调度模型量化评价指标间的相互作用及协调发展程度,采用Dagum基尼系数分析区域发展水平差异。结果表明:53个样本城市的综合发展水平平均得分由2014年的0.099增至2022年的0.156,累计增幅57.58%,综合发展水平稳步提高,但得分较低,整体发展水平仍待提高;评价指标的耦合协调度持续改善,耦合协调度等级由轻度失调过渡至濒临失调,整体耦合协调度仍处于较低水平;样本城市的综合发展水平差异主要来源于区域间差异,区域间差异年均贡献率为40.18%,缩小区域间发展差异是降低商贸服务型国家物流枢纽承载城市综合发展水平差异扩大的关键。

Abstract: To promote high-quality development of commerce logistics and regional coordination, 53 cities designated as national commerce-service logistics hubs are selected as sample cities. Based on panel data from these sample cities from 2014 to 2022, an evaluation index system is constructed with five dimensions: economic development level, commerce development level, infrastructure level, logistics development level, and talent-information potential. The entropy weighted-technique for order preference by similarity to ideal solution method is used to calculate comprehensive development level scores. A coupling coordination degree model is emplayed to quantify interactions and coordination among indicators, while the Dagum Gini coefficient is applied to analyze regional disparities. Results indicate that the average comprehensive development level of 53 sample cities increases steadily from 0.099 in 2014 to 0.156 in 2022, representing a cumulative increase of 57.58%, though the overall level remains low and requires improvement; the coupling coordination degree continuously improves, transitioning from mild imbalance to marginal imbalance, yet overall coordination stays suboptimal; regional disparities primarily stem from inter-regional differences, with an average annual contribution rate of 40.18%, making inter-regional gap reduction essential for curbing the expansion of overall disparities.
