Research On The Structure Features Of City Tourism Network In Pearl River-West River Economic Belt

The way of spatial diffusion is changing gradually under the background of information age.The phenomenon of saltatory diffusion is increasing.The development of tourism directly leads to the change of urban tourist space structure.Along with the social informatization construction of informatization of education,the operation space of tourism industrial organization is reintegrated because of information flow.At present,tourism website has become the primary information channel for tourists to obtain information and make decisions.The spatial structure of tourism information flow and its usage play an important role in the behavior of tourist,so it affects the distribution pattern of tourist flow.At the same time,many scholars have found that tourism information flow plays an obvious role in guiding tourist flow.Based on combing the domestic and foreign related research results,this paper focuses on the study of urban tourism network structure,draws lessons from analysis method of urban network proposed by P.J.Taylor,taking 11 core cities of Pearl River-West River economic belt as an example(The following is referred to as the economic belt).Based on the analysis of tourism rank scale distribution difference,function scale and function status of every city,this paper focused on the perspective of tourism information flows,analyzed city tourism network spatial structure and hierarchy of nodes.First,based on reference to domestic and foreign literatures on the scale difference of urban tourism,the study uses different levels of measurement index and method model to comprehensively and accurately express the change characteristics of urban tourism differences in the economic belt.And this paper makes an in-depth and comprehensive analysis of the variation characteristics and distribution rules of urban tourism scale differences from 3 aspects:domestic,international and total tourism revenue.It reduced the possibility that most scholars used single angle analysis to draw unreasonable conclusions.It is found that the tourism scale distribution in economic belt cities is quite different,and its size distribution is in a high aggregation.The scale difference of urban tourism is an important factor leading to the irrational structure of urban tourism function,and the low level of economic development in small cities is the weakness of its tourism development.Secondly,based on the previous article,two indexes were taken--the total number of tourists and total tourism revenue of urban tourism accounts for GDP.And the urban tourism function intensity division model of the economic belt is constructed,which is to judge the city tourism function strength comprehensively from two dimensions of function scale and status.The result shows that the function structure of urban tourism is unreasonable and the scale and functional status of urban functions are mainly concentrated in the middle and low levels.The scale of tourism functions is mainly concentrated in a few large and medium-sized cities and the overall size distribution of urban tourism is unreasonable;The degree of specialization of urban tourism is low,and the overall tourism function intensity of the economic belt needs to be improved,so the underlying reason for this situation is the irrational structure of the urban tourism information network.These cities can rely on national and regional development strategies to promote the adjustment and upgrading of regional tourism industrial structure,optimize the structure of tourism function and improve the tourism grading system of economic zone.Thirdly,because of the lack of statistics on the "flow" of tourist flow in China,the depth and research process of the domestic tourist flow have been greatly restricted.This paper attempts to explore the"flow space"structure by using the D-value model and the advantage flow analysis method with the view of tourism information flow.This provides a new perspective and new train of thought for the research of urban tourism network.The results show that the structure of tourist information flow needs to be optimized in the economic belt.From the perspective of tourism information flow,the polarization characteristics of urban tourism "flow space" structure are significant.Tourism information flow mainly focuses on large and medium-sized tourist cities,and the disadvantaged status of tourism information flow in small cities is significant;The two cities in Baise and Chongzuo have significant sub regional characteristics.They will be important nodes in the future urban tourism network structure.Finally,based on the above 3 parts,the research conclusions are summarized,this paper puts forward the policy recommendations for optimizing the spatial network of urban tourism,and analyzes the innovation and shortcomings of the study and direction for future research prospects.
