港航后勤服务要素与港口体系的协同效率研究

Study on Synergetic Effect of Port Backup Service Elements and Port System

港航后勤服务要素是港口体系的重要支撑,两者的相互协同有助于港口区域的可持续发展。为了识别港航后勤服务要素与港口体系的协同关系,运用DEA模型对长江三角洲地区主要城市港航后勤服务要素与港口体系的协同效率进行实证分析。研究结果显示:(1)长江三角洲地区各城市的港航后勤服务要素与港口体系协同效率存在较大差异;(2)宁波舟山的协同性最好,而上海、南通、苏州和南京均存在不同程度的协同效率问题;(3)部分城市存在资源投入过多和港口集装箱吞吐量不足的问题,最后针对港航后勤服务要素配置与港口产出不足提出相关建议。

Port and shipping backup service elements are theimportant support of the port system, and the synergy betweenthe two can contribute to the sustainable development of the port area. In order to identify the synergetic relationship be-tween port and shipping backup service elements and the portsystem, the DEA model was used to empirically analyze thesynergetic efficiency of port and shipping backup service ele-ments and port system of the main cities in the Yangtze Riv-er Delta. The results show that： （1） There is a big differencein synergy efficiency between port and shipping backup ser-vice elements and the port system among cities in theYangtze River Delta; （2） Ningbo-Zhoushan has the best syn-ergy, while Shanghai, Nantong, Suzhou and Nanjing all havedifferent degrees of problems in synergy efficiency; （3 ） Somecities have problems of over-investment of resources and inad-equate throughput of port containers. Finally, this paper pro-poses some suggestions for the allocation of port and shippingbackup service elements and the port output shortage.
