中部六省会展城市间的“虹吸效应”研究

Research on the“Siphon Effect”Among the Exhibition Cities of Six Central Provinces

在会展城市发展过程中,发达会展城市对欠发达会展城市的资源吸引现象日益明显。以中部六省的会展城市为研究对象,通过改进城市引力模型,对会展城市之间的虹吸效应进行分析,发现中部六省每省有一个核心会展城市,会展城市之间存在着“虹吸效应”,距离核心会展城市越近的欠发达会展城市受到的“虹吸效应”越强烈。随着时间的推移,大部分欠发达会展城市受到的“虹吸效应”不断增加,最终导致极化效应。

In the process of the development of exhibition cities,the resource attraction of developed exhibition cities to underdeveloped exhibition cities is becoming increasingly obvious.Taking the exhibition cities in six central provinces as the research object,this paper analyzes the“siphon effect”among exhibition cities by improving the urban gravity model.It is found that there is a"siphon effect"among exhibition cities in the six central provinces,and each province has a core exhibition city.The closer to the core cities,the stronger the"siphon effect"is.Most underdeveloped exhibition cities are subject to increasing siphon effect over time,which eventually leads to a polarization effect.
