Abstract: The continuous evolution of tourism public crises caused by human factors will bring huge impacts and potential threats to the regional tourism industry. Good control and effective prevention of tourism public crises have become the focus of attention of scholars. This study builds a SEIR evolutionary game model based on the theory of communication dynamics and evolutionary game theory, explores the game relationship between the local government and the tourism industry's strategic choices, and the evolution path of tourists' emotional cognition under the different behavioral decisions of both parties, and analyzes the evolution of the system to benign and stable The state process is in accordance with the law, in order to provide decision support for the government. The simulation experiments show that after the outbreak of the tourism public crisis, the positive attitudes of local governments and the tourism industry can efficiently repair tourists' negative emotional perceptions and prevent the tourism crisis from continuing to evolve; local governments use fines and non-material penalties to regulate the behavior of the tourism industry. Through policy subsidies and incentives to increase its driving force in choosing and standardizing business decisions, and at the same time establishing a strict market access system, it can restore tourists' confidence and restore the image of tourist destinations, ultimately benign guidance and control and effectively prevent tourism public crises.
