Study on the Coupled and Coordinated Development of Tourism Economy and Ecological Environment in Chengdu City，china

The sustained growth of Chengdu's urban tourism economy has brought the relationship between tourism and ecological environment into sharp focus, becoming a key issue in both scholarly research and public policy discourse. In order to promote the positive interaction between the two, this study constructs a set of index system to evaluate the coupled and coordinated development of tourism economy and ecological environment based on the theory of ecological economics, coupled and coordinated theory and sustainable development theory, and based on the actual development background of Chengdu city. This study employed the entropy weighting approach to quantitatively measure the development status of the tourism economy and ecological environment in Chengdu during the period from 2013 to 2022. Subsequently, a coupling coordination model was utilized to examine their interrelationship and the level of coordinated development. The findings indicate that Chengdu's tourism economy and ecological environment have experienced continuous improvement in their comprehensive benefit index over the past decade. This development trajectory can be categorized into three distinct phases: a period of rapid growth, a phase of fluctuation and adjustment, and a stage of relative stability. The observed coupling and coordination levels between the tourism sector and ecological environment demonstrate clear phase characteristics, underscoring the presence of a tightly interwoven and interactive relationship. Specifically, economic indicators such as tourism value-added exert a positive influence on the ecological environment, whereas certain ecological indicators impose constraints on the further enhancement of the coupling and coordination level. These findings offer theoretical support and policy-oriented recommendations for advancing the integrated development of Chengdu's tourism economy and ecological environment.
