The teaching reform ideas and practices are elaborated: the teaching objectives are oriented towards meeting the needs of the industry, enterprises, schools, and students, and project-based teaching method is used to cultivate students’ professional ability to use high-tech to solve real problems in tourism service enterprises. Teaching resources such as practice bases are used to exercise students’ critical thinking spirit and innovation and entrepreneurship ability. Through process assessment and multiple evaluation mechanisms such as team collaboration and project reporting, students’ communication and collaboration abilities are strengthened. It helps cultivate high-quality and specialized talents urgently needed for the high-quality development of the tourism service industry.展开更多

However, the rigorous or rather fuzzy. This paper demonstrates the rationality and necessity of OPEC＇s price band policy by using the game theory. We conclude that OPEC has the incentive to limit its price within a specific range if the game period is sufficiently long. This incentive comes either from preference for long-term interest or from future expectations. In such a way, OPEC tries its best to maximize its profit with the quota-price dual policy and plays a price stabilizing role in the future world oil market.展开更多
