Coupling Coordination Analysis of Urban Tourism Environment Quality and the Tourism Economy: A Case Study of Nanjing City

There is a complex interaction between the quality of the urban tourism environment and the tourism economy. The former is the key to sustainable development of the tourism economy, which, in turn, also has an impact on the urban tourism environment. Therefore, understanding the coupling coordination relationship between them is crucial. This paper aims to construct a comprehensive evaluation index system of urban tourism environment quality system and the tourism economic system and adopts the entropy method to weigh the indexes. The comprehensive evaluation model and coupling coordination degree model are exploited to conduct an empirical analysis of the changes in Nanjing’s tourism environment quality, tourism economy comprehensive development level, and coupling coordination degree from 2009 to 2020. The results show that the coupling coordination degree shows a fluctuating upward trend overall. In particular, the traffic environment and tourism benefits have the most significant impact on the coupling system, indicating that relevant departments need to consider these key factors when making macrodecisions.
