Analysis On The Evolution Of Regional Tourism Economic Spatial Structure And Its Influencing Factors In The Yangtze River Delta

Regional economic development has become the general trend.Urban agglomeration is very important to drive the development of surrounding areas.In the field of tourism,it is also urgent to form urban agglomeration integration,so as to promote the development of regional tourism integration and regional development.With the 《development outline of the Yangtze River Delta integration plan》,the integration of the Yangtze River Delta has become one of the national strategies.Promoting the integration of the Yangtze River Delta with the tourism integration of the Yangtze River Delta is in line with the current background of the times.Based on this,this study used the social network analysis method and constructed a matrix with the help of the tourism gravity model to analyze the overall network density,degree centrality,betweenness centrality,closeness centrality,structural hole and other data of the network spatial structure of the Yangtze River Delta in 2010,2015,2019 and 2020,and conducted Concor cluster analysis,exploring the evolution law of cyberspace structure of different urban individuals in the Yangtze River Delta in the past ten years.At the same time,according to the tourism center of gravity model and tourism standard deviation ellipse model,ACG GIS spatial analysis method was used to explore the evolution of the overall tourism center of gravity and tourism standard deviation in the Yangtze River Delta in 2010,2015,2019 and 2020,so as to complement each other with the urban individuals studied in the network spatial structure,and better explored the spatial structure of tourism economy in the Yangtze River Delta.Finally,QAP and qualitative analysis were used to explore the factors affecting the spatial structure of tourism economy network in the Yangtze River Delta and the evolution degree of the factors affecting the tourism focus.The main conclusions of this study are as follows:(1)In the past decade,the overall connection of regional tourism spatial structure in the Yangtze River Delta has been strengthened,the node status of core cities has shifted,and it tends to gather in neighboring cities under the influence of the COVID-19.In the evolution of centrality,the degree centrality in Hangzhou has surpassed that in Shanghai in recent years.The closeness centrality and betweenness centrality of the Yangtze River Delta region have shifted from Shanghai to Hangzhou,Hefei and Nanjing.Under the COVID-19,the spatial structure is more inclined to the agglomeration of adjacent cities.(2)In terms of the evolution of tourism gravity,the overall change range is small,but there is a trend of migration to the West and south.The COVID-19 interrupts this trend and brings the elliptical range of tourism standard deviation back to the level of 2015.(3)In the evolution of influencing factors,economic development conditions and regional proximity have a positive impact on the formation of cyberspace structure,while traffic conditions have a negative impact.In recent years,the impact of economic development conditions has weakened and the impact of regional proximity has deepened.From2010 to 2020,tourism resource endowment has experienced an evolution process from impact to insignificant impact.The evolution of centrality and epidemic situation in the spatial structure of tourism network have an impact on the evolution of tourism focus.Based on the main conclusions,this study puts forward countermeasures and suggestions for urban nodes,Yangtze River Delta and tourism enterprises.For the city itself,they should vigorously develop their own economy and improve their economic level.The core city should play a leading role and the edge city should actively integrate.For the Yangtze River Delta region,it should promote regional clusters,open up regional plates through advantageous cities in structural holes,promote joint marketing and strengthen regional traffic construction.For tourism enterprises,they should formulate multiple joint routes and carry out in-depth cooperation among enterprises.It is helpful to the study of tourism integration in the Yangtze River Delta and to provide reference for the study of tourism integration in the Yangtze River Delta.
