Coupling and interaction between tourism eco-efficiency and new urbanization in the Yangtze River Economic Belt: based on the perspective of uncoupling coordination

Facing the severe situation of environmental problems, coordinating the sustainable development of tourism and the construction of new urbanization is conducive to regional sustainable development. Based on the perspective of uncoupling coordination, this paper evaluates the coordination relationship between the sustainable development of tourism and the development of new urbanization, analyzes their temporal and spatial characteristics, and analyzes the restriction mechanism behind the uncoordinated relationship from the dynamic interaction. The findings are as follows: (1) At present, Shanghai, Jiangsu and Anhui are at a low level of uncoordinated development, while other regions are at an antagonistic uncoordinated development stage. (2) The regional difference of uncoupling coordination degree between tourism eco-efficiency and new urbanization is getting smaller and smaller, and it tends to develop in a balanced way, which accords with the strategic goal of coordinated development. However, the degree of uncoupling coordination changes from relatively weak aggregation to relatively strong aggregation. (3) From the long-term dynamic impact, the eco-efficiency of tourism has a negative impact on the development of new urbanization in Shanghai, Chongqing, Yunnan and a positive impact on Jiangsu and Hubei, with the contribution rates of 26%, 66%, 58%, 24% and 51%, respectively. New urbanization has a positive impact on the eco-efficiency of tourism in Anhui and a negative impact on Guizhou, with the contribution rates of 65% and 57%, respectively. The uncoupling coordination relationship and the interaction between the two systems are closely related.
