A Study On The Three-dimensional Spatial Coupling Coordination Of Tourism In Four Provinces And Cities In The Yangtze River Delta

From the perspective of three-dimensional space,this paper explains the connotation of tourism physical space,tourism information space and tourism human-oriented space and constructs an index system,taking four provinces and cities as the research area.a variety of spatial analysis and econometric methods are used,such as comprehensive evaluation model,coupling coordination degree model and geographic detector model.Measure the development level,coupling coordination degree and the influence degree of each sub-index on the coordination degree of tourism ternary space system from 2013 to2020.Combined with the actual development of the four provinces and cities in the Yangtze River Delta,this paper further summarizes the empirical results,and puts forward the optimal promotion path to promote the coordinated development of tourism in the four provinces and cities in the Yangtze River Delta.The main research contents are as follows:(1)This paper analyzes the comprehensive development level of tourism three-dimensional space in four provinces and cities in the Yangtze River Delta.The three-dimensional comprehensive evaluation index of tourism in the four provinces and cities shows an upward trend,which is characterized by "low rise and high end".There is a certain similarity in the changes of the three spaces,which is shown as the turning point in 2016.before the turning point,the comprehensive evaluation index of each province and city is in a state of fluctuation,and after the turning point,the comprehensive evaluation index of each province and city shows an accelerated upward trend.On the whole,the comprehensive development level of tourism physical space is the highest,tourism human-oriented space is the second,and tourism information space is the lowest.(2)This paper studies the spatio-temporal evolution characteristics of three-dimensional spatial coupling degree and coupling coordination degree of tourism in four provinces and cities in the Yangtze River Delta.From the overall change trend of three-dimensional spatial coupling degree and coupling coordination degree,the correlation degree among tourism physical space,tourism information space and tourism people-oriented space has reached a high level and stable,but the coordinated development level of the three tourism spaces still needs to be improved.From the evolution characteristics of coupling coordination degree,the coupling coordination level of pairwise tourism space is better than that of three spaces.Although the coupling coordination development level of three spaces is increasing,it is still in the stage of moderate coupling coordination.(3)This paper explores the driving factors that affect the three-dimensional spatial coupling coordination of tourism in four provinces and cities in the Yangtze River Delta.From the analysis of index detection,the tourism ternary space is independent of each other by the core factors,during which the interaction formed by the superposition of the two spaces is greater than the explanatory power of their respective independent functions to the dependent variables.the influence of secondary indicators in different spaces on different provinces is also slightly different.The conclusion of the study makes a cognitive exploration on the connotation of destination tourism spatial theory,and provides support and suggestions for the empirical study of tourism ternary spatial relationship among the four provinces and cities in the Yangtze River Delta.
