西部陆海新通道沿线枢纽城市物流业高质量发展水平测评:区域差异与动态演进

Evaluation of High-quality Development Level of Logistics Industry in Hub Cities along New Western Land-sea Corridor:Regional Differences and Dynamic Evolution

西部陆海新通道沿线枢纽城市实现物流业高质量发展对助推我国加快构建“陆海内外联动,东西双向互济”的对外开放格局,推动西部地区高质量发展具有重要意义。基于2015—2021年西部陆海新通道沿线19个国家物流枢纽城市的面板数据,构建物流业高质量发展综合指标体系,采用熵权-TOPSIS法对其物流业高质量发展水平进行测度,运用Dagum基尼系数、核密度估计法分析通道沿线枢纽城市物流业高质量发展水平的区域差异和分布动态。结果表明:①通道沿线枢纽城市物流业高质量发展水平整体呈现上升趋势,但发展水平不高,且空间发展不均衡。②枢纽城市物流业高质量发展水平总体差异呈现“先上升后下降”的倒U型趋势,该差异主要源自地区内的差异。

The high-quality development of the logistics industry in hub cities along the New Western Land-sea Corridor is of great significance in promoting China’s accelerated construction of a“land-sea internal and external linkage,east-west mutual assistance”opening-up pattern and promoting high-quality development in the western region.Based on panel data from 19 national logistics hub cities along the New Western Land-sea Corridor from 2015 to 2021,this paper constructed a comprehensive indicator system for high-quality development of the logistics industry.The entropy weight-TOPSIS method was adopted to measure the high-quality development level of the logistics industry,and the Dagum Gini coefficient and kernel density estimation method were applied to analyze the regional differences and distribution dynamics of the high-quality development level of the logistics industry in hub cities along the corridor.The results are as follows.①The overall highquality development level of the logistics industry in hub cities along the corridor is on the rise,whereas the development level is not high and the spatial development is uneven.②The overall difference in the high-quality development level of the logistics industry in hub cities shows an inverted U-shaped trend of“first increasing and then decreasing”,which mainly stems from regional differences.
