| 英文摘要 |
| In this paper, we explore the intrinsic law of supply chain coordination of the emergency quantity discount contract in response to emergencies under bilateral information asymmetry and risk aversion of one participant. First, we set up the incentive and engagement constraint conditions for participants scientifically with "altruistic principal" theory, and we construct the emergency quantity discount contract model based on the stochastic market prices under the conditions of bilateral information asymmetry and risk aversion of one participant. After that, we analyze the influence of information asymmetry and risk aversion on the decision variables in the supply chain, the performance of the supply chain and its members. Then we verify the results through simulation of specific examples. The results show that under the condition of determined degree of risk aversion for participants, the more accurate the information forecast between the supply and marketing parties, the greater the expected revenue of the supply chain. However, as information transparency increase, so does the revenue of risk-averse participants, while the income of risk-neutral participants will reduce with the drop of information transparency accordingly. We also find that the the higher the risk aversion degree of participants, the greater their own benefits will be based on the determined information asymmetry state. Finally, we come to the conclusion that participants'' awareness of risk prevention is conducive to avoiding risks in the case of bilateral information asymmetry. But retailers of risk aversion have comparative information advantage, while risk-averse suppliers does not have this kind of characteristic. |
