粤港澳大湾区城市群城市规模分布特征及经济联系

City Distribution Characteristics and Economic Relations of Guangdong-Hong Kong-Macao Greater Bay Area

运用城市首位度、位序—规模法则、核密度估计、基尼指数等实证研究方法分析粤港澳大湾区城市群的规模特征,同时引入社会网络分析方法分析粤港澳大湾区城市群经济联系关联网络。研究结果表明:粤港澳大湾区城市群的首位城市并未显示出明显的优势,呈现广州深圳双核心的发展态势;人口聚集趋势较为明显,首位城市与中小城市的人口规模存在较大的差距;超大城市和特大城市吸引力较强,未来城市规模转型不易;城市之间的经济联系及协作能力不强;城市间经济联系的等级特征明显。未来要推动粤港澳大湾区高质量发展,提升城市间的经济协作能力以及经济联系强度,进一步提升城市群的综合竞争力。

This paper uses empirical research methods such as city first degree,order-scale rule,nuclear density estimation,and Gini index to analyze the scale characteristics and rules of the Guangdong-Hong Kong-Macao Greater Bay Area urban agglomeration.At the same time,it introduces social network analysis methods to analyze the Guangdong-Hong Kong-Macao Greater Bay Area urban agglomeration.The research results show that the first city in the Guangdong-Hong Kong-Macao Greater Bay Area urban agglomeration did not show obvious advantages,showing the development trend of dual cores in Guangzhou and Shenzhen;the trend of population clustering is more obvious,and there is a large gap between the population size of the first city and the small and medium-sized cities;megacities are more attractive,and it will not be easy to transform the sizes of cities in the future;economic ties and collaboration capabilities between cities are not strong;the hierarchical characteristics of economic ties between cities are obvious.In the future,it is necessary to promote the high-quality development of the Guangdong-Hong Kong-Macao Greater Bay Area,enhance the capacity of economic cooperation and economic ties between cities,and further enhance the comprehensive competitiveness of urban agglomerations.
