Abstract：Considering the random price condition caused by emergency， a three-stage supply chain model under the quantity flexibility contract was constructed to solve the optimal ordering and pricing strategy. Meanwhile， the models of no-emergency and market price stability were established to explore the changes of supply chain coordination under different scenarios. In addition， flexibility coefficients were changed as a variable to analyze the impact on the overall revenue and related parties' decisions. The results showed that， there is only one optimal ordering strategy when the flexibility coefficients are constant. Only by adjusting the benchmark contract properly， could we coordinate the response to emergency. When the flexibility coefficients are variable， there is only a single supply decision， while the unique optimal ordering decision does not exist. Finally， a numerical example proved that changes of flexibility coefficients would not have influence on the overall optimal revenue.
