With the tourism economy becoming a new pillar industry,tourism industry cluster and optimization and upgrading of tourism industrial structure gradually become a hot issue concerned by researchers and tourism industry.This paper,taking Guizhou Province as an example,studies the relationship between the tourism industrial cluster and the optimization and upgrading of the tourism industry structure in the backward areas,and puts forward some practical suggestions for development.It is hoped that it will help Guizhou’s tourism industry’s sustained and healthy development and enhance its regional competitiveness,and it can also be used for reference for other provinces and cities.Theoretically,it reviews the relevant literatures on the optimization of tourism industrial cluster and tourism industrial structure at home and abroad,analyzes the mechanism between the tourism industry cluster and the optimization of tourism industrial structure,and constructs an index for the optimization of tourism industry cluster and the optimization of tourism industrial structure.On this basis,this paper puts forward the hypothesis that the phenomenon of industrial cluster in the tourism industry and the tourism industry cluster are helpful to promote the optimization and upgrading of the tourism industry structure.In the empirical analysis,through the distribution of scenic spots,hotels and hotels,we discuss the status of Guizhou tourism industry cluster.By calculating the location entropy index,Herfindahl-Hirschman Index and the space Gini coefficient,we judge whether the tourism industry cluster exists.We determine the stability of the Guizhou tourism industry structure by calculating the structural similarity coefficient,the structural change elasticity index of income and the entropy of the structural system.In this paper,the difference and improvement of the structure of tourism industry between Guizhou and the national tourism industry is made through the grey correlation theory.This paper demonstrates the relationship between the tourism industrial cluster and the optimization of tourism industry structure through the empirical methods such as correlation analysis and time series regression analysis.The research finds that tourism industry is clustered.In the current stage,there are industrial structure optimization and upgrading space in Guizhou tourism industry,such as long-distance transportation,catering and other structures,and tourism industry cluster promotes the optimization of tourism industrial structure.It is suggested that Guizhou province should strengthen top-level design,promote horizontal cooperation between regions,strengthen personnel training,promote industrial cluster and industrial structure optimization and upgrading,strengthen infrastructure construction and optimize long-distance traffic and catering structure.There are some shortcomings in the construction of tourism industrial structure optimization criteria and related indicators.And,Because the data is difficult to obtain,this paper is not very reasonable in measuring the changes in the structure of the tourism industry structure,and testing the relationship between the industrial cluster and the optimization of the tourism industrial structure in two places.In the future,there is still space for optimization and improvement in the empirical analysis. |
