摘　　要：基于城市流的中心城市外向功能联系研究视角,依据全国287个中心城市对外服务能力及其时空的变化,探讨区域空间结构模式的形成与演化过程。研究认为,中心城市外向功能联系构成区域空间结构形成演化的主要动力。我国区域空间结构从西部到中东部、从中部及东北到东部沿海地区,总体上呈现出低水平均衡分布、单核心极化—扩散、多核心极化—扩散、高水平均衡4个演化阶段。中心城市对外服务能力区域差异明显,长三角、珠三角、环渤海湾地区的外向功能较强,城市群的集聚程度和对外服务能力呈现出规模递增趋势。Based on center cities＇ external function links of urban flows, according to the 287 center cities＇ service capabilities and its change of 10 years, the paper studied the regional spatial structure model and its evolu- tion. Research finds that the center cities, relying on its external service functions, bring centripetal polarization and outward pervasion function, thus the complex economic flows and close economic links have formed inside the region, which affect and determine the regional spatial structure finally. Regional spatial structure can be divided into four evolution stages of low-level equilibrium distribution, single core polarization -diffusion, multiple core po- larization -diffusion, and high-level equilibrium. From the west to the east, from the midland and northeast to the eastern coastal area, regional spatial structure overall presents this four stages. Chinese central cities＇ external service capabilities make a significantly difference in different provinces, the provinces and urban agglomerations of Yangtze River Delta, Pearl River Delta and Bohai Bay area have stronger external function contacts and service ca- pabilities, make the regional space economic links intimately, have developed network spatial structure. The mid- land and west center cities＇ external service capabilities are weak, and also are the spatial economic links, so pole core and pole axis spatial structures are the main types.
