Study On The Spatial Correlative Networks And Influencing Factors Of Domestic Tourism Economy In The Middle Reaches Of The Yangtze River

The Multiple city clusters are spatially represented as economic factors flowing to the economic relationship and then fed back to economic growth.The same is true of the spatial relationship for tourism economy.With the development of city networks,the division of labor,resource sharing,and information flow among cities are all related to the evened-out development of the clusters.There is one of the key points for spatial correlation of tourism economy in the study of tourism economic balance in urban agglomeration.In order to making and enriching the spatial correlation study of regional tourism economy,This paper analyzes the spillover effect and changes of domestic tourism economy in 31 cities,and probes into the structural characteristics of spatial correlation network of domestic tourism economy of it,which also optimizes the cooperative development within urban agglomerations and can effectively help formulate regional coordinated development policies.This article collects 19 years of domestic tourism-related data in 31 cities and uses Granger causality and gravity models to measure the spatial spillover effects and changes of domestic tourism economy of its.Based on it,the features and changes of the domestic tourism economic spatial relevant network between 31 cities were analyzed by the SNA.Finally,QAP analysis was used to test the influencing factors of the spatial association network of domestic tourism economy in urban agglomerations,the following results are reached:1)Since 2000,domestic tourism development in the middle reaches of the Yangtze River has been steady,Domestic tourism revenue of the clusters has increased notably.There are obvious differences in the development of tourism economy within urban agglomerations,but it tends to converge.A total of 456 economic spillovers were generated in 31 cities.There were 262 one-way causalities and 99 two-way ones.one-way was greater than two-way.Tourist economic spillovers were more common,but the tourism economic interaction was insufficient.A strong spillover relationship occurs between cities that are closer.2)Comparing the spillover effects of different time sections,it is found that the tourism economic spillover effects of the Yangtze River are becoming pretty clear.Two-thirds of the cities have expanded their spillover ranges,and one-third of the cities have only expanded or Expansion of the overflow range.The capacity of investment for Zhu-zhou,Huang-gang,Xiang-tan was better;Wuhan and Changsha's ability to invest abroad has increased significantly;The cities' "gold-absorbing" capacity has grown significantly for Xin-Yu,Ping-xiang,E-zhou,and Xiao-gan;3)In 2018,the domestic tourism economy spatial association network in the circles was stable and the network structure was symmetrical.Its need to be redoubled;Domestic tourism economic relationship does not form a complete closed map.The City Circles of Wuhan Metropolitan Area,Chang-Zhu-Tan city gruop,Xiang-Jing-Yi city group are closely linked to the domestic tourism economy.The tourism economic association network centered on a single city is relatively stable.The cities of Huang-shi,Huang-gang,Yi-yang,Heng-yang,Jingdezhen,and Ping-xiang have strong centrality.4)Comparing the characteristics of the tourism economic spatial association network of the urban agglomeration in 2012 and 2018,it is found that the tourism economic links of the urban agglomerations in the middle reaches of the Yangtze River are becoming closer,the overall network structure is increasingly optimized,the tourism economic benefits are more balanced,the entire network is becoming more circular.There are more and more individual networks associated with the tourism economy.The tourism economic momentum of the middle reaches of the Yangtze River has gradually spread from Chang-Zhu-Tan to Xiang-Jing-Yi,Wuhan City Circle,and Chang-zhu-tan City Circle.5)The smaller the difference in the scale of tourism investment and the difference in economic,the closer the tourism resources and the domestic tourist source market,the greater the difference in tourism employment,the higher the convenience of transportation,and the higher the degree of spatial correlation between domestic tourism economies.
