Study On The Structure And Causes Of Tourism Economic Network Of Node Cities In The Silk Road Economic Belt

Since the Silk Road Economic Belt was proposed by Chairman Jinping Xi in 2013,it has gradually changed from loose alliance to integration,the Silk Road tourism belt has also become one of the top 10 national tourism belts.Under this development background,cities along the Silk Road Economic Belt will have closer tourism economic links,in order to study the relationship between the tourism economy of the cities along the Silk Road Economic Belt and the position of the cities in the economic relationship,it is necessary to comprehensively analyze their spatial structure of tourism economy.The purpose of this paper is to provide a new perspective for the study of tourism development of the Silk Road Economic Belt and to promote the coordinated development of the Silk Road Economic Belt in the northwest and southwest lines.Firstly,this paper introduces the background,significance and methods of the research,and reviews and summarizes the development status of related research at home and abroad.Secondly,the gravitational model is modified,it chooses the data of total tourism income and total number of tours of 25 main tourist nodes in the northwest and southwest sections of the Silk Road Economic Belt in 2009,2013 and 2017.It uses the social network analysis method,density,centrality,structural hole data,core-edge model and other indicators,to study the evolution characteristics of economic connection network and spatial structure of major cities along the Silk Road Economic Belt.Then,this paper uses QAP regression analysis to analyze the impact of location differences,traffic accessibility differences,tourism resources endowment differences,industrial structure differences and other factors on the tourism economic spatial network of the Silk Road Economic Belt.Finally,it points out the existing problems of regional tourism economic network,and proposes corresponding countermeasures and suggestions,which is to strengthen regional tourism cooperation,develop tourism development platform,consolidate the leading role of core cities,promote the coordinated development of cities,improve traffic access conditions,and achieve brand sharing strategies.
