The optimal pricing strategies and coordination contract of providers of low carbon tourism products and services (TCP) and an online travel agency (OTA) are discussed based on altruism preference of decision makers. A competition model is established to compare and analyze the revenue, pricing strategies and coordination conditions in Stackelberg game model. According to the study and comparison results, altruism preference can directly influence decision-makers' decisions and supply chain. Meanwhile, information symmetry can determine decision making. If altruism preference of TCP increases, the overall profit of the supply chain will be enhanced in spite of the information symmetry. When Altruism Preference of OTA platform increases, the overall profit of the supply chain will decrease in the case of information symmetry. As for information asymmetry, the overall supply chain profit will decease with increasing altruism preference. Moreover, numerical examples are taken to analyze the profits of OTA and TCP in revenue coordination. Finally, some suggestions are proposed for the establishment of coordination contract.
