In recent years,the transformation and upgrading of cultural tourism,quality and efficiency improvement have become a hot direction of China’s economic and social development and a hot topic discussed in academia.Especially since the establishment of the Ministry of Culture and Tourism in 2018,the development of culture and tourism has achieved integration in administrative relations,but there are still certain shortcomings and shortcomings in the connotation and depth of its integrated development.The development of cultural tourism actively responds to the development pattern of domestic circulation as the main body and domestic and international dual circulation promoting each other,gradually changing from resource dependence to creative development,and its comprehensive role in national economic and social development has gradually become prominent.How to continuously improve the core competitiveness of cultural tourism has become an urgent problem to be solved,and exploring the spatiotemporal evolution law and influencing factors of the coupling and coordination level of cultural tourism product supply and cultural economic development is conducive to improving the core competitiveness of cultural tourism.Taking the theory of human-land relationship,coupling coordination theory,industrial cluster theory and sustainable development theory as the main references,this study first selects the main evaluation indicators of product supply and economic development of cultural tourism,constructs a coupling coordination model of product supply and economic development of cultural tourism,and then calculates the coupling coordination level of 31 provinces,autonomous regions and municipalities in China from 2010 to 2020,and divides them into different development stages and types according to the calculation results.Then,the LISA method is used to analyze the spatiotemporal evolution and interaction characteristics of the coupling coordination level,and finally the GTWR geographically weighted regression model and Tobit model are used to analyze the influencing factors of the coupling coordination level,and countermeasures are proposed.This study not only enriches the theoretical research on the coupling and coordination level of product supply and economic development of cultural tourism,but also provides a case study for the sustainable development of cultural tourism.The main conclusions of this paper are:Firstly,from 2010 to 2020,the overall situation of product supply and economic development of national cultural tourism was good and continued to grow steadily,the overall situation of product supply in the northwest region developed the fastest,and the overall situation of economic development in the southwest region was relatively stable.The comprehensive evaluation value of China’s cultural tourism product supply and economic development increased rapidly and widely,from 0.1739 in 2010 to0.6165 in 2020,an increase of 254.43%.The overall economic development of cultural tourism is faster than the overall situation of product supply,and the growth rate of the comprehensive evaluation value of cultural tourism economic development(average annual growth rate of 18.90%)is higher than that of product supply comprehensive evaluation value(average annual growth rate of 10.30%).The comprehensive evaluation value of the supply of cultural tourism products in the northwest region grew the fastest,with an average annual growth rate of 18.31%,and the comprehensive evaluation value of cultural tourism economic development in the southwest region maintained stable growth,with an average annual growth rate of 18.39%.The product supply and economic development of cultural tourism in all provinces in the country show a good development trend,but different provinces show obvious development characteristics.Secondly,from 2010 to 2020,the coupling and coordination level of national cultural tourism product supply and economic development developed rapidly,from low coupling and low coordination to high coupling and high coordination,and the coupling coordination degree developed from 0.2008 in 2010 to 0.8195 in 2020,with an average annual growth of 15.10%.The level of coupling coordination has changed from serious imbalance and lagging economic development to well-coordinated economic lag,and there is still much room for improvement in its development from quantitative expansion to qualitative improvement.The coupling and coordination level of the six regions of East China,Central China,North China,South China,Southwest China and Northwest China continued to improve.The level of coupling coordination in Northeast China decreased significantly,and it shifted from high coupling and high coordination to low coupling and low coordination.The coupling coordination level of all provinces and regions in the country has improved,and the average coupling coordination degree has increased by 29.48%.Thirdly,the coupling and coordination level of national cultural tourism product supply and economic development has a development trend of decreasing cooperation capacity from east to west.The characteristics of horizontal spatial agglomeration of the coupling and coordination of product supply and economic development of cultural tourism were obvious,the characteristics of low-low agglomeration in Northwest China were obvious,and the characteristics of high-high agglomeration in East China were obvious.Northwest China has the highest degree of spatial dependence,North China has the highest degree of activity,inter-provincial cooperation capacity is gradually increasing,the number of provinces,autonomous regions and cities with self-stability and neighborhood stability temporal and spatial transition types has decreased,East China,Central China and South China are HH→HH spatial change types,and Northwest,Southwest China and Heilongjiang and other provinces,autonomous regions and cities are LL→LL spatial change types.The local spatial structure of the coupling and coordination level between provinces is highly dynamic,and the characteristics of strong coordinated development relationship mainly in Beijing and other provinces,autonomous regions and municipalities are obvious,while the weak correlation characteristics in northwest,south and northeast China,as well as Jiangsu and Shandong,are obvious.The coupling and coordination level of product supply and economic development of provincial-level cultural tourism in China is higher than that of mountainous provinces,and the gap has widened.Fourthly,the four aspects of travel system,resource density,service capacity and economic level all play a significant role in the development of the coupling and coordination level of cultural tourism product supply and economic development.The economic level has the greatest influence on the level of coupling and coordination,while the resource density has the least influence on it.Implement countermeasures and suggestions in five aspects: "improving the systematic cognition of cultural tourism,optimizing the supply capacity of cultural tourism products,tapping the driving force of economic development according to local conditions,improving the basic guarantee capacity of cultural tourism,and differentiating to improve the ability of regional development",and promote the sustainable and healthy development of the coupling and coordination level of cultural tourism product supply and economic development. |
