This paper selects Shanxi Province as the study area and constructs a comprehensive evaluation index system of tourism, urbanization and ecological environment in Shanxi Province. Measurement methods such as polar deviation standardization, entropy value method and coupling coordination degree are adopted to measure the comprehensive development index, coupling degree and coupling coordination degree of tourism development, urbanization level and ecological environment quality in Shanxi Province from 2012 to 2022. The results show that from 2012 to 2022, the comprehensive development level of tourism, urbanization and ecological environment in Shanxi Province continues to rise, and the urbanization level continues to be higher than the tourism and ecological environment development levels, while the system coupling and coordination degrees are low, showing a dysfunctional state. In the future, while vigorously increasing the level of urbanization and developing tourism in Shanxi Province, it is necessary to pay more attention to ecological environmental protection and achieve the coordinated development of tourism, urbanization and ecological environment.
