The Coupling Coordinated Relationship between High-quality Tourism Development and Common Prosperity in the Yellow River Basin

This study explores the coordination mechanism between high-quality development and common prosperity in the tourism sector. Using methods such as the entropy weight TOPSIS method, coupling coordination model, kernel density, Dagum Gini coefficient, and decomposition analysis, the study empirically examines the spatio-temporal evolution of the coupled and coordinated relationship between high-quality tourism development and common prosperity in the Yellow River Basin from 2011 to 2019. The results show that both the levels of high-quality development and common prosperity in tourism increased during the research period, with common prosperity generally outpacing high-quality tourism development. Both indicators exhibit notable spatial heterogeneity. The coupling and coordination between high-quality tourism development and common prosperity has steadily improved, with a lagging pattern in high-quality tourism development as the predominant type. Furthermore, kernel density analysis reveals that the coupling and coordination level between the two systems has increased, while regional disparities have diminished. The overall Gini coefficient of the coupling coordination degree between high-quality tourism development and common prosperity fluctuates downward, with regional differences identified as the primary source of variation
