小型城市群形成条件研究——以云南个开蒙建为例

Research on the Conditions for the Formation of Small Urban Agglomerations—Taking the Ge Kai Meng Jian in Yunnan Province as an Example

小型城市群的培育和发展对于推进区域协调发展具有重要意义。文章首先基于增长极理论和经济辐射的特点,构建了一种统计指标,并提出相应理论假说;然后基于现有研究成果拟合出城市辐射范围与地区生产总值之间的数量关系,用以测度城市的经济辐射半径;最后利用样本区域2020年的地区生产总值数据以及地理空间数据,对提出的理论假说进行实证。研究结果表明:所构建的统计指标在测度某区域是否具备城市群形成条件方面具有一定的可行性;个开蒙建等市所构成的区域已具备城市群形成的基本条件,在该区域可以构建城市群。文章的最后,根据研究结果提出相关政策建议以期推进个开蒙建城镇群的培育与发展。

The cultivation and development of small urban agglomerations is of great significance for pro-moting coordinated regional development. Based on the characteristics of growth pole theory and economic radiation, this paper first constructs a statistical index and proposes a corresponding theoretical hypothesis;then, based on the existing research results, the quantitative relationship between urban radiation range and regional GDP is fitted to measure the economic radiation radius of the city;and finally, the regional GDP data and geospatial data of the sample area in 2020 are used to empirically verify the proposed theoretical hypothesis. The results show that the statistical indicators constructed have certain feasibility in measuring whether an area has the conditions for the formation of an urban agglomeration;the area composed of cities such as Ge Kai Meng Jian already has the basic conditions for the formation of urban agglomerations, and urban agglomerations can be constructed in this area. At the end of the article, relevant policy suggestions are put forward according to the research results in order to promote the cultivation and development of urban agglomerations in Ge Kai Meng Jian.
