摘　　要：长江下游12.5 m深水航道的建成对长江南京以下港口与城市的发展具有重要影响。将港口系统与城市系统相结合,采用二阶段SBM-DEA模型对长江南京以下9个港口城市的可持续效率进行测算,结果表明:长江三角洲地区港口城市可持续效率值逐年增长;在空间分布上,可持续效率存在局部地区的效率值波动,呈现临海港口高于内河港口。产业结构、对外贸易量对港口城市可持续效率具有显著正向影响,而经济水平、人口密度和人才数量对其具有负向影响。研究丰富了港城互动方面的研究,可为促进港城绿色建设、提高港口城市可持续发展效率提供有益参考。The completion of 12.5 m deep water navigation channel in the lower reaches of the Yangtze River has an important impact on the development of port cities from Nanjing to Shanghai.In this research,we put the port system and the urban system into a holistic analysis system framework,the sustainable efficiency of nine port cities below the Nanjing on the Yangtze River is calculated by using the two stage SBM-DEA Model.The results showed that the sustainable efficiency of different port cities was all increased from 2011 to 2019.In terms of spatial distribution,the sustainable efficiency fluctuates in some regions,and the oceanic port was higher than the inland ports.And the industrial structure and foreign trade volume have a significant positive impact on the sustainable efficiency of the port cities,but economic level,population density and the number of talents have a negative correlation with sustainable efficiency of port cities.The comprehensive research on Port Geography and Urban Geography would enrich the understanding about the port-city interaction,and hopes that could contribute to the future researches on the port city sustainable development.
