Abstract
As the two most important nodes in the tourism supply chain, the competition, as well as the cooperation relationship between scenic spots and tourism enterprises, has a profound impact on the healthy development of the tourism industry. In this paper, we establish a dual-channel tourism supply chain model by making many assumptions about the operations of scenic spots and tourism enterprises. According to repeated game theory, we find that there is a certain trigger strategy for equilibrium strategy between scenic spots and tourism enterprises, and the cooperation-cooperation strategy is the optimal choice for scenic spots and tourism enterprises at this time.
