Abstract: The high-quality development of tourist industry is an important foundation and strong support for promoting Chinese-style modernization. Scientifically measuring and evaluating the level and the changing trend of high-quality development of regional tourism has important theoretical and practical significance. On the basis of defining the connotation of high-quality development of tourist industry, this paper constructs an evaluation index system of high-quality development of tourist industry under the guidance of the new development concept and the sustainable development theory; then it measures and evaluates the level of high-quality development of the tourist industry in 30 provinces in China. The results show thatfrom 2011 to 2019, the high-quality development level of tourism in China generally shows an upward trend year by year, and the industrial development level, the social harmony level, the innovation ability, the cultural and tourism integration degree, and the ecological protection level have been significantly improved. From 2020 to 2021, due to the impact of the COVID-19 epidemic, although the overall development level and the industrial development level have declined, the scores of the other four indicators continued to rise, which reflects that the high-quality development level of tourism of China is constantly improving with the process of high-quality development of China. However, the high-quality development level of tourism in different provinces is significantly different, and the overall development quality is at a medium level. There is still a long way to reachthe high-quality development standards. In the future, to improve the high-quality development level of tourism, we should focus on optimizing the industrial structure, improving the quality of tourism innovation, deepening the integration of culture and tourism, strengthening ecological protection, and other aspects.

Key words: tourist industry, high-quality development, index system, entropy evaluation method
