Summary: With the increasing competition, hotels are seeking cooperation with the third party promoters to increase the occupancy rate. How hotels cooperate with promoters becomes a hot topic in hotel industry. This paper analyzes a market with one dominant hotel and two competing promoters and constructs their profit model by using game theory method. Then the optimal strategies are derived in the case of decentralized and centralized setting and some factors influencing their strategies are analyzed. The paper further proposes a coordination contract that can achieve Pareto improvement for the whole system. Our studies show that : 1) the profit of two competing promoters increases as the price of hotel increases; 2) As the degree of competition among promoters is increasing, promoters will reduce their profit to improve the promotion efforts, which makes the profit of the hotel and the coordination level of supply chain increase. We also validate the effectiveness of this contract and show the sensitivity analysis of parameters through other numerical examples.
