Spatial temporal evolution of tourism destination competitiveness and its coordination with ecological environment in coastal areas of China

It's an important basis to clarify the coordination between the spatiotemporal evolution of tourism destination competitiveness (TDC) and the ecological environment for promoting the sustainable development of tourist destinations. This study used the entropy weight method, spatial analysis method and the center of gravity model to evaluate the spatiotemporal evolution characteristics of tourism competitiveness and ecological environment in China's coastal areas from 2005 to 2020. It also used the coupled coordination model to analyze the coordination relationship between the two. The results show that the overall level of tourism competitiveness along China's coastal areas is on the rise, with significant spatial differences between different provinces, and the center of gravity of tourism competitiveness shifting to the south. The ecological environment of China's coastal areas tends to improve as a whole, and gradually changes from relative balance to north-south divergence. The increasing rate of tourism competitiveness of China's coastal areas is faster than the progress of ecological environment improvement, and the two have not yet shown benign coupling characteristics but rather have reached a synchronous state.
