Recognition Of Regional Tourism Network Structure From The Perspective Of Flow Space

Tourism flow,as an important factor of regional connection,plays an important role in the development of regional tourism.On the one hand,with the further advancement of the country's new urbanization process,urban agglomerations have gradually become the regional body on which tourism development depends.Due to its unique advantages in the process of urban agglomeration construction,tourism is conducive to promoting the optimization and adjustment of the industrial structure in urban agglomeration and promoting the integration process of urban agglomeration.As the largest urban agglomeration,the Yangtze River Delta urban agglomeration is also one of the largest tourist sources and tourist destinations in China.Its intra-city tourist flows are very frequent,so it is typical to explore the regional tourism network structure with it as the research object.On the other hand,with the "blowout" development of informatization today,the tourism industry is widely dependent on the Internet.However,the academic community has not paid much attention to virtual tourism flow,and there are few studies on virtual tourism flow.Therefore,this study takes the realistic and virtual tourism flow networks of 26 cities in the Yangtze River Delta as research objects,and uses GIS spatial analysis,social network analysis,community discovery algorithm and other methods to explore the structural characteristics of realistic and virtual tourism flow networks in the Yangtze River Delta urban agglomerations,and QAP correlation analysis method is used to analyze the driving factors of the tourism flow network in the Yangtze river delta.Finally,the following main conclusions are drawn:(1)On the whole,the realistic and virtual tourism flow networks of the Yangtze River Delta urban agglomerations have significant spatial and temporal differences.In terms of time evolution,the realistic and virtual tourism flow networks of the Yangtze River Delta urban agglomeration continue to develop in time,and the network scale continues to expand.In terms of spatial evolution,the internal heterogeneity of the realistic tourism flow network is stronger than the virtual tourism flow network in the Yangtze River Delta urban agglomeration.And the realistic tourism flow network shows a significant spatial agglomeration effect,with large internal differences;while the virtual tourism flow network shows that tourism flows tend to develop in a balanced manner.(2)In the spatial pattern,the realistic and virtual tourism flow networks of the Yangtze River Delta urban agglomeration exhibit different spatial and distribution characteristics.First of all,the realistic and virtual tourism flow networks show multicenter development.Taken together,the core node cities of the realistic tourism flow network are Shanghai,Suzhou,Hangzhou,and Wuxi;the core node cities of the virtual tourism flow network are Shanghai,Suzhou,and Nanjing.Hangzhou.The main spatial flow takes place between these core cities and spreads to the Yangtze River Delta.Secondly,the trunk network of the realistic tourism flow is in a “Z” shape,and the virtual tourism flow is developing toward a polygon.Finally,the tourism flow of the realistic tourism flow network has significant administrative boundary characteristics,while the administrative boundary of the virtual tourism flow network is gradually broken,which is shown in both the network structure and the community structure.(3)In terms of structural stability,the realistic tourism flow network structure of the Yangtze River Delta urban agglomeration is relatively stable,and the virtual tourism networks' changes greatly.From 2011 to 2015,and then to 2018,both the spatial structure,the flow structure,the network structure,and the community structure have shown relatively stable time changes of the realistic flow network,while the virtual flow network has shown great changes.(4)In terms of influencing factors,the tourism flow of the Yangtze River Delta urban agglomeration is significantly affected by factors such as comprehensive tourism development factors,economic development level factors,comprehensive transportation development factors,and informatization development factors,while government policy driving factors are not significant.Based on this,the driving mechanism of the tourism flow network of the Yangtze River Delta urban agglomeration is constructed,among them,the driving force of the tourist source area,the pulling force of the tourist destination and the regional comprehensive coordination and promotion force play a positive driving role,and the regional comprehensive distance resistance will have a certain negative driving role.(5)Compared with the realistic tourism flow network,the virtual tourism flow network of the Yangtze River Delta urban agglomeration has certain guidance.With the acceleration of regional tourism integration in the Yangtze river delta,its realistic tourism flow network has also developed rapidly with the development of social economy.arc The future development direction is to further promote tourism integration,reduce administrative isolation,narrow internal differences,and move towards balanced development.This research not only helps to expand the research scope of flow space theory;promote the integration of tourism discipline research with other discipline theories and methods;promote the integration of tourism research with the theories and methods of other disciplines;and it is beneficial to enrich the research content and methods of tourism network structure,expand the data sources of tourism flow research,and provide some new perspectives for tourism flow research.At the same time,it is beneficial to clarify the tourism network structure of the Yangtze river delta region in the new era,and provide reference opinions for the optimization of the regional tourism network structure of the Yangtze river delta region,so as to promote the regional tourism integration of the Yangtze river delta region.
