The Improvement And Application Of Tourism Gravity Model Based On The Heterogeneity Of Tourism Resources

As an important quantitative research method of tourism attraction,tourism gravitational model has always been one of the hot topics in the tourism field.Quantifying the tourism attraction between cities helps to analyze the problem of quantity and direction of tourist flow between tourist-guest source and tourist destination,which is valuable for the study of regional tourism spatial pattern,structure of tourist origin area,Tourist destination distribution and urban tourism development orientation.However,the traditional tourist attraction model is a system composed of three explanatory variables,which are attraction,outing ability,and space resistance between the tourist-guest source and tourist destination.Tourism attraction and tourist thrust is regarded as two independent variables,which leads to the attraction of a tourist destination to different tourist-guest source is the same.In fact,the attraction of tourist destinations to different tourist-guest source is inconsistent.Therefore,the traditional tourist attraction model lacks a factor that explains why the attraction of the tourist destination to different tourist-guest source is different.In this study,in order to improved the traditional model,tourism resource heterogeneity factor as a new variable is added to the tourist attraction model.In order to verify the improved model,this study applied the tourism attraction calculation between 256 cities in the whole country to analysis the tourist attraction-dislocations of tourist volume and the mechanism of urban tourism gravitation.The content of the paper is divided into six parts.The first part(the first and second chapters)points out the research background and significance of the paper,puts forward the research objectives and contents,explains the research methods,and makes a review of the related research progress and theoretical basis.The third chapter is the second part,including the research object description and the data explanation.The fourth chapter is the third part,including the calculation of the influence of the national tourism resources,analysis of the influence structure of tourism resources in various cities,and calculation of the heterogeneity of tourist resources between cities.The fifth chapter is the fourth part.This chapter joins the tourist attraction heterogeneity factor into the tourist attraction model.In this chapter,the calculation method of other factors in the model is adjusted,and the improvement of the model is explained in detail.The sixth chapter is the fifth part.It compares the model before and after the improvement,and discusses the rationality of the improvement.The sixth chapter is the fifth part.After the improvement of the model,the rationality of the improvement is discussed,and a case study is made for tourism attractiveness,passenger traffic dislocation and the mechanism of urban tourism attraction.The last part is the results of the paper,the main conclusions,and the analysis of the deficiencies of the paper,and prospects for the future research direction.
