摘要
由核心城市及其所影响的周边城市组成的都市圈是现代城市发展的一个重要空间单元。通过对核心城市的经济引力与场强范围以及圈层划分的计算,确定金融地理学中的"核心—边缘"模型的空间范围,从地理学的角度对金融加以认知与研究,使其具有一定的实用性,同时也深化了金融地理学的理论研究。采用定量方法引入了引力与场强模型,对都市圈范围进行了系统研究。在前人研究的基础上,以广州都市圈为例,将都市圈的最大空间考察半径由300千米扩展至600千米,在较为广阔的地理范围内考察了广州金融都市圈所覆盖的金融空间范围并作出界定。结果显示,广州都市圈的大致范围包括25个大小不等的地级市,并在此基础之上对广州金融都市圈进行圈层划分、时间效应分析与金融中心建设提出建议。
It＇s influence space within the srrounding cities objective composed of metropolitan coordination region, which is a important spatial unit of urban development. By calculation of the economic gravity, field intensity and the region division to ascertain the ＂core-edge＂ model in the financial geography. It has a certain practicality to cognize and research from the perspective of geography and can deepen financial geography theoretical connotation. The article adopt quantitative methods and introduce gravitational and field models to study the metropolitan coordination region. On the basis of previous studies,taking Guangzhou metropohtan region for instance, this paper extend the metropolitan spatial investigation radius from 300km to 600km, examine the generic metropolitan spatial scope of Guangzhou in a broad range of geographical scope and define it. The final results show that the Guangzhou metropohtan region including of 25 sizes prefecture-level cities, and on this basis to propound that region division and financial center construction for the Guangzhou Extensive Region.
