Based on the system theory and synergy theory, a collaborative evaluation index system of tourism industry and tourism public service is constructed, and the coupling coordination model is used to measure and evaluate the coupling coordination relationship between tourism industry and tourism public service in 11 counties of Guilin from 2010 to 2020. And then the grey correlation method is used to explore the influencing factors. The results show that, firstly, the comprehensive development of tourism industry and tourism public service is gaining momentum, but the level of tourism development is relatively low. Secondly, the coupling degree and coordination degree between tourism industry and public services are steadily rising, but the basis of coordination degree is relatively poor which needs to be improved. Thirdly, tourism industrial structure, tourism public information and tourism public environment are the main factors affecting the coordinated development of tourism industry and tourism public services. Accordingly, for the coordinated development of Guilin tourism industry and tourism public services, the full play should be given to the role of government to formulate corresponding policies according to local conditions and to keep up supply-side structural reforms.
