本文基于港口形成演化视角,从海岛港口资源优势和区位优势出发,认为长山群岛港口地域组合形成演化过程有四个过程:起步阶段、初步发展阶段、快速发展阶段和空间外拓阶段;并归纳出海岛港口地域组合形成演化模式,认为海岛港口地域组合按照"岛域主导-岛际主导-区际主导"的顺序进行演化,形成岛域主导模式、岛际主导模式和区际主导模式三种演化模式。本文认为,长山群岛港口地域组合目前正处于从岛际非均衡集中阶段向岛际均衡分散阶段的过渡阶段。在此基础上,本文探究了海岛港口地域组合形成演化的主要机制。

China's island ports have abundant resources and good geographic conditions. In addition, they are densely-distributed near the developed areas in the Southeast Coast of China. All the conditions can provide new development space for coastal ports system. First, this paper researches the evolution of ports regional combination in Chang-Shan Archipelagos and thinks that there are four stages in the evolution of ports regional combination in Chang-Shan Archipelagos, namely, start stage, developing stage, quickly-developing stage and space-expanding stage. Next, it analyzes the evolutionary patterns of island ports regional combination from the perspective of ports evolution according to the resources strength and location strength of island ports. The researchers hold that the evolution of island ports regional combination is from ‘island-regional leading’ to ‘inter-islands leading’ and then to ‘inter-regional leading’. Three types of evolutionary patterns of island ports, namely, island-regional leading pattern, inter-island leading pattern and inter-regional leading pattern have respectively been concluded. It contends that the evolution of ports regional combination in Chang-Shan Archipelagos is in the transition phase from inter-island disequilibrium concentration stage to inter-island equilibrium spread stage. Finally, this paper gives an further study on the mechanism of ports regional combination. Three operational mechanisms, government behavior mechanism, port-hinterland mechanism and aggregation spread mechanism and competitive-cooperation mechanism have been elicited.
