摘要: 运用 1995 年以来的中国航空统计数据, 分析了中国城市体系格局和时间变迁。其主要方法包括数据描述及重力模型和模糊参数等定量方法。得到如下结论:目前中国城市体系中, 前两位的枢纽城市大多为中心城市或城市群;上海、北京两大全球城市强化了在全国的枢纽机场的地位; 特大城市群间的航空流反映了长三角地区的经济中心城市强盛的区域带动势头;机场的复合流量枢纽度方面, 北京的得分最高, 其次是厦门、西安等;1995?2004 年枢纽度变化情况也能够清晰反映出城市的竞争力。

Abstract: This paper examines the Chinese urban systems in terms of domestic air flows since 1995 based on gravity model and the fuzzy variable method. Main findings are as following: The first and second tier cities of contemporary urban systems are mostly core cities of megalopolis or mega-city regions; Shanghai and Beijing further strengthened their position as national airline hubs and primary cities. And interactions among mega-city regions reflect the uprising of the Yangtze River Delta Region as the leading region of the nation. Based on gravity model analysis, Beijing enjoys the biggest hubness score followed by Xiamen etc. In 1995-2004, the hubness changes can clearly reflect the recent competitiveness of mega-cities or regions.

Key words: air flow, Chinese urban system, core city, hubness
