Spatio-temporal evolution of supply-demand-support system coupling coordination and its influencing factors of Chinese cultural tourism

In recent years, the transformation and upgrading of cultural tourism, and the development of quality and efficiency improvement have become hot topics of concern and academic discussion in China's economic and social circles. Based on the coupling coordination theory, this study constructs a coupling coordination model of product supply and economic development of cultural tourism, calculates the coupling coordination level of 31 provinces (autonomous regions and municipalities) in China from 2010 to 2020, divides the specific development stages and types according to the calculated results, and then analyzes the spatiotemporal evolution of the coupling coordination level, and then analyzes its influencing factors according to the GTWR model. The results are as follows: (1) From 2010 to 2020, the global spatial positive correlation between the coupling and coordinated development ability of cultural tourism supply-demand-support system is prominent, the dynamics of local space is strong, and the cooperation ability shows the characteristics of strong east and weak west. (2) The ability of coupling and coordinated development decreases from east to west, but the development advantage of southwest China is obvious, among which the self-activity degree of northwest region is low, while southwest region is the highest. Central China has the highest degree of spatial dependence, while South China has the lowest. The southwest region is the traditional advantageous region of China's cultural tourism development, and maintains a relatively stable development trend, while the cultural tourism in the northeast region has weakened. (3) The degree of openness has a large trend of influencing ability, while the development of other five influencing factors, such as scientific and technological development, maintains a relatively stable ability. In the stage of imbalanced development, the influence of openness, scientific and technological support, and potential consumption has decreased, while the influence of the influencing factors of household consumption and industrial support has remained unchanged, and the influence of economic security has increased. The influencing ability of six influencing factors, such as the degree of openness in the transitional development stage, remained unchanged. The influencing ability of the degree of openness in the coordinated development stage decreased, while the influencing ability of five influencing factors, such as scientific and technological support, maintained the characteristics of stable growth, and the self-development ability continued to increase. Recognize and explore cultural tourism as a "community", put forward specific countermeasures and suggestions, and realize the sustainable and healthy development of cultural tourism product supply and economic development.
