Study On Coupling And Coordinated Development Of Exhibition Industry In Yangtze River Delta Urban Agglomeration

Yangtze River Delta urban agglomeration as one of the most active areas of China's economy,and It's also an important area for the development of China's exhibition industry.Due to the successful hosting of the World Expo and the G20 summit will be the Yangtze River Delta cities to the exhibition boom to the peak,This is not only the opportunity for the integration of Yangtze river delta urban agglomeration exhibition integration,is also a challenge.On the one hand,large-scale international activities will not only build exhibition venues,but also greatly improve the city's infrastructure and enhance the city's visibility;On the other hand,the Yangtze River Delta cities have participated in the exhibition market competition,invest a lot of manpower and material resources and financial resources to build venues,but the exhibition venues utilization is low,some exhibition venues face "idle" danger.This paper studies the development of the exhibition industry in the Yangtze River Delta urban agglomeration.Hope from the overall understanding of the development level of Yangtze River Delta urban agglomeration exhibition industry,and the difference between the development level of the exhibition industry in each city.It is found that the comprehensive development index of the exhibition industry of the Yangtze River Delta is ladder-shaped Distribution.According to the gradient recursion theory,the development level of the exhibition industry in the Yangtze River Delta is classified,the first gradient is Shanghai,the second gradient includes Hangzhou,Suzhou and Nanjing,as the secondary center exhibition city,The third gradient includes Ningbo,Wuxi,Jinhua,Changzhou,Wenzhou,Shaoxing,Taizhou,Zhenjiang,Jiaxing,Hefei,Nantong,the fourth gradient includes Yangzhou,Taizhou,Xuzhou,Yancheng,Huai'an,Wuhu,Lianyungang and Maanshan.And then use ArcGIS according to the in size of the Yangtze River Delta urban agglomeration exhibition industry comprehensive development index and the three subsystems development index to draw.From the perspective of space,the development of the Yangtze River Delta urban agglomeration industry generally presents a" Single-core three-axis multi-axis" spatial pattern.And then through the coupling degree of the relationship between the three subsystems,the coupling degree of each city are higher,indicating that the three subsystems in an orderly development of the state.and then use the coupling coordination model to calculate the Yangtze River Delta.Through the spatial autocorrelation analysis,we study the spatial distribution characteristics and significance of the coupling competitiveness of the Yangtze River Delta urban agglomeration in the exhibition area.The spatial distribution characteristics and significance of the coupling in the whole region are revealed,and it is shown in which areas the high observation value or low observation value of the space gathering.Finally,due to the large difference in the development of the exhibition industry in the Yangtze River Delta,the development coordination is not high,so this article provides suggestions for narrowing the difference of development between different cities exhibition industry.Hoping to enhance the overall development of the Yangtze River Delta urban agglomeration industry,Accelerate the integration process of the Yangtze River Delta urban agglomeration exhibition industry.
