中文摘要：

就港口的空间关系而言，近代以来，上海与宁波两港大致经历了枢纽港支线港到枢纽港大型深水直挂港的转变，而且未来还极有可能会形成双枢纽港的运作模式；双方的这种关系尽管是多方面因素综合作用的结果，但总体而言，自然条件与经济发展规律的共同作用应是其中的最为关键性的原因。如果未来的上海港与宁波港之间真能形成一种双枢纽港的运行模式，那么，不仅长江三角洲地区港口体系的运作合力会得到有效的发挥与展示，而且也必将会提升我国的港口在全球港口体系中的竞争实力与地位。

英文摘要：

If a thread mode such as pair hinge harbor between Shanghai Harbor and Ningbo Harbor can be formed in future, not just thread cooperation of port system in Chang Chiang Delta region, but also inevitably competition strength and ：status of ports of our country will be promoted.
