Tourism Ecological Efficiency and Sustainable Development in the Hanjiang River Basin: A Super-Efficiency Slacks-Based Measure Model Study

The Hanjiang River is one of the major tributaries Yangtze River, and Basin serves as an important link connecting western eastern regions China. As a significant tourist destination, development tourism industry in great significance for promoting local economic, social, environmental sustainability. study spatiotemporal evolution ecological efficiency beneficial optimizing investment resource elements protection high-quality area. In this paper, we used Super-Efficiency Slacks-Based Measure Model to calculate 12 cities from 2010 2019 measured its spatial agglomeration using ArcGIS software. results show that during period, presented phased characteristic first rising then falling over time heterogeneity decreasing downward-middle-upward staircase pattern spatially. addition, distribution exhibited obvious clustering dependence, with low-level homogenization phenomena, which requires strengthening cooperation coordination among neighboring achieve more efficient utilization higher-quality product development.
