一体化视角下长三角世界级机场群发展现状及优化措施

 分析了长三角机场群的发展现状，提出当前长三角机场群面临密度偏低、机场群与城市群空间匹配失衡、协同分工尚未形成、零和思维依然存在等问题，从机场密度、等级体系、功能协同和区域管治等4个方面介绍了欧美成熟世界级机场群的发展状况和建设经验，对长三角建设世界级机场群提出4点建议：一是建设上海大都会区机场群先行，提升环沪机场密度；二是以主要都市圈为抓手，分步有序建设长三角机场群；三是实施差异化定位，打造功能协同的都市圈机场群；四是设置跨行政区机场群管治机构，促进跨区协调。

Problems and countermeasures of worldwide airport clusters under Yangtze River Delta Integration

The pattern of several airports sharing a regional air transport market is getting more and more popular. Under the background of the rising of the urban agglomeration, this linkage pattern between the urban agglomeration and the airport clusters is formed generally in the world. This paper clarify the related concepts, such as the airport clusters and the multiairport region, then based on analyzing the development of the airport clusters in the Yangtze River Delta, we make the following four observations: the density is still lower than that of the mature airport clusters in the world, there are space imbalances between the airports and the cities, the coordination among the airports has not yet been formed, and the zero-sum thinking still exists. With the mature airport clusters as the benchmark, we analyze the airport density, the hierarchical system, the functional coordination and the regional governance in the world. Based on the above analysis, we put forward four suggestions as follows: firstly, the airport clusters in Shanghai metropolitan should lead the integration of Yangtze River Delta airports, with the airport density around Shanghai being improved. Secondly, the airport clusters in the main metropolitan areas, such as Nanjing and Hangzhou, will be the important points. Thirdly, it is urgent for the main hub-airports and the main metropolitan areas to take a diversified positioning strategy. Lastly, in the Yangtze River Delta, a trans-administrative-area governance organization should be established, for smooth communication and coordination among airports.
