基于综合引力模型与首位度的城市群分析

Urban group analysis based on the integrated gravitational model and the first degree

采用首位度与综合引力模型的研究方法,选取地区生产总值、规模以上工业生产总值等14项体现城市综合发展的指标,通过熵值法合理赋权后对海峡西岸城市群内所有城市进行综合分析,揭示城市之间的相互影响关系和城市等级情况.结果表明:福州是海峡西岸城市群的核心城市,其综合质量为城市群内首位,但其城市引力值较厦门低,核心城市的带动作用稍显不足.厦门是次核心城市,城市引力最高,发展势头较好.泉州、温州和漳州等是城市群中的主要城市,处于较好的发展水平.海峡西岸城市群整体展现出蓬勃的发展力,但是,高质量核心城市对次级城市的辐射能力不够;主要城市之间的相关影响不够密切,带动作用较弱.增强高质量城市的核心带动力和城市之间的密切联系将对海峡西岸城市群整体实力的提升起关键作用.

Based on the 14 indicators, such as Gross Regional Product and Gross Industrial Output Value above Designated Size, of comprehensive development of the city by the first degree, comprehensive gravity model, and entropy method, a comprehensive analysis of all cities on the west side of the straits shows that Fuzhou is the core city of the west coast of the Straits, and its comprehensive quality is the first place in the urban agglomeration. However,its urban gravity value is lower than that of Xiamen, and the driving role of the core city is not strong. Xiamen is a core city with the highest gravity and good momentum of development. Zhangzhou, Wenzhou and Quanzhou are the main cities in the urban agglomeration with a good level of development. The Hereynian urban agglomeration has shown vigorous development as a whole. However, the radiation capability of high quality core cities to seeondary cities is not enough, and the correlation between main cities is not enough close, and the driving role is weak. Strengthening the core power of the high quality cities and the close ties between cities will play a key role in improving the overall strength of the Hereynian urban agglomeration.
