| Tourism flow research has always been the focus of academic research.Tourism flow network structure is a new branch of tourism flow research.Its network structure research has far-reaching impact on understanding the current situation of regional tourism development,rational layout of tourism space,scientific planning of tourism routes,and promoting the healthy and sustainable development of tourism.A series of changes,such as the development of social economy,the adjustment of holiday system,and people's yearning for a better life,have changed people's tourism concept.The traditional group travel mode can no longer meet the personalized and diversified tourism needs of modern people.More and more people choose free,in-depth and distinctive self-help tours.Self-help tours have become the mainstream tourism mode and their proportion in the tourism market is increasing.With the development of Internet technology,modern people have become "screen people" and more and more people are willing to share their travel experiences on tourism social networking sites.These travel notes are a portrayal of tourists' real travel activity information,making them reliable data sources for tourism research,and the authors of travel notes are mostly self-supporting groups.In view of this,this paper selects Shandong Province as a case study,On the basis of combing the relevant literature,it uses social network analysis method and spatial analysis theory to make an empirical study on the spatial network structure of self-help tourism flow in Shandong Province.Firstly,the sample characteristics are analyzed.Secondly,construct the network structure of self-service tourism flow in 16 cities of Shandong Province;Thirdly,the social network analysis method is used to analyze the network structure from two levels:node and whole network.Finally,the spatial structure of self-help tourism flow in Shandong Province is constructed and compared with the overall spatial structure of tourism in Shandong Province.The study found that:(1)Self-help tourists from other provinces in Shandong mainly come from developed provinces such as Beishangguang.July,August and November are the peak periods of self-help tourism in Shandong.Jinan,Qingdao,Tai'an,Yantai,Weihai and Jining are the main cities visited by self-help tourists.(2)There is a close relationship between tourism nodes."Jinan,Qingdao,Weifang,Yantai,Weihai,Zaozhuang,Rizhao,Tai 'an and Jining" are closely linked in the node network.Zibo is only linked to Jinan and Weifang,Linyi is only linked to Zaozhuang and Rizhao,Dongying is only linked to Weifang,Yantai and Weihai,Dezhou is only linked to Jinan,Binzhou,Heze and Liaocheng are not linked to any city.(3)The index values of each node are different,showing an obvious hierarchy.Jinan,Tai 'an,Qingdao,Yantai and Weifang are the core cities.Jining,Rizhao,Weihai and Zaozhuang are sub-core cities.Dongying,Zibo,Linyi and Dezhou are marginal cities.Binzhou,Heze and Liaocheng are isolated islands in the network.(4)The overall network of self-help tourism flows in Shandong is not closely linked,and there are three internal small groups closely linked:"Jinan,Tai 'an,Qingdao","Zaozhuang,Jining,Rizhao","Dongying,Yantai,Weihai,Weifang".(5)The spatial structure of self-help tourist spots in Shandong is similar to the overall tourism in Shandong,while the linear spatial structure presents a more complex network structure.On this basis,suggestions are put forward to promote tourism development in Shandong Province. |
