Research On The Symbiosis Of The Yangtze River Delta Tourism City Cluster Based On Multi-type Network Interaction Analysi

The strength of the high speed development of our country in recent years,the national quality of life improved significantly,also growing demand for tourism,tourism has become a modern service industry development and industrial transformation and upgrading of the new growth point,and the support and development of tourism industry is in line with " Clear waters and green mountains are as good as mountains of gold and silver " green development concept,is an important part of sustainable development goals.The paper focuses on the symbiosis of tourism city clusters using multi-dimensional network data.Taking the Yangtze River Delta city cluster as the research object,the thesis uses web crawler technology to obtain various types of new data such as traffic commuting time,OTA reviews,Baidu index,and review IDs,calculates the traffic distance network,impression distance network,tourist concern network,and tourist co-travel network among Yangtze River Delta cities,and uses social network analysis to analyze the node structure and overall characteristics of each network.Finally,the interaction analysis of the relationship between the four networks is borrowed from regression analysis,and the synergistic coupling degree between different dimensions of tourism networks in the Yangtze River Delta tourism city cluster is calculated based on the interaction analysis.The following conclusions are drawn:First,both the traffic distance network and the impression distance network have a negative impact on the tourists’ attention network,but the impression distance has a relatively greater impact.When the distance between the destination and the place of departure is farther,the tourists’ attention to the destination will decrease;similarly,when the city impression of the destination deviates from the tourists’ preference and familiarity,the tourists’ attention and search will also be reduced;However,in comparison,the weakening degree of impression is stronger.It can be understood that when impression preference and traffic distance are options,tourists are more willing to choose the travel with a long commuting distance and a general impression rather than a tour with a large deviation and a general travel distance.City.Therefore,tourist city clusters should shorten the traffic distance between cities,which is more conducive to tourists’ attention.Second,the tourists’ attention network has a positive impact on the tourists’ co-tour network.The greater the common concern of tourists to the destination city,the higher the actual travel probability of tourists.Third,Shanghai,Nanjing and Hangzhou are the "one axis and two wings" of the Yangtze River Delta urban agglomeration.They are at the core of development,have the highest comprehensive and coordinated development level and maintain a high-speed growth trend,and the development of Huzhou and Hefei should not be underestimated.watch for.However,most cities are still in the stage of high symbiosis and low growth or low symbiosis and low growth.This type of phenomenon shows that there is still an unbalanced development in the integrated development of the Yangtze River Delta tourism,which needs to be further improved in the future.The paper combines the results of the above analysis to make suggestions for the higher quality integrated development of tourism in the Yangtze River Delta.
