基于后勤服务网络的港口群空间协同研究——以扬子江城市群为例
|
摘要
基于港口吞吐量和港口后勤服务企业数据,综合选用基尼系数、偏移增长和复杂网络等方法,对扬子江城市群的港口物流空间结构展开分析。研究显示:(1)在2000—2015年里扬子江城市群的港口吞吐量实现了快速增长,但这种快速增长是不均衡的;(2)扬子江城市群基本上形成了以南京为核心,南京—苏州、南京—无锡为骨干链条的辐射状港口后勤服务网络;(3)港口吞吐量和后勤服务企业组织系数在空间上具有协同效应,协同度总体呈现由苏南向苏中下降的趋势。最后针对扬子江城市群港口物流发展中存在的缺乏合作、同质竞争严重、港口主体过多、削弱总体竞争力和交通联运水平低等问题,提出了相对应的建议。
Based on the data of port handling capacity and port logistics service enterprises,this paper uses Gini coefficient,migration growth and complex network to analyze the cooperative evolution of port logistics in the Yangtze River urban agglomeration.The results show that the port handling capacity of the Yangtze River urban agglomeration increased rapidly from 2000 to 2015,but the rapid growth was unbalanced.The Yangtze Riverurban agglomeration has basically formed a radial port logistics service network with Nanjing as the core,Nanjing-Suzhou and Nanjing-Wuxi as the backbone chain.There is the port handling capacity and the organizational coefficient of logistics service enterprises have synergistic effect in space,and the synergy degree generally shows a downward trend from southern Jiangsu to central Jiangsu.Finally,the author puts forward some suggestions in view of the lack of cooperation in the development of port logistics in the Yangtze River urban agglomeration,the serious homogeneous competition,the excessive number of port subjects,the weakening of the overall competitiveness and the low level of transportation and combined transport.
