在制造商的资金收益率大于零售商资金收益率的情况下，以报童模型为基础，研究了资金收益对回购契约的影响。系统预期利润变为与批发价相关，利用拉格朗日方程求解了满足零售商参与约束、同时使系统和制造商预期利润取得最大值的契约参数。与不考虑资金收益情况下的供应链协调不同的是：订货批量大于相应批发价下不考虑零售商参与约束的最优订货批量；若零售商的保留利润一定，则回购价增大；回购价可以大于批发价，批发价可以小于制造商的边际生产成本。
在製造商的資金收益率大于零售商資金收益率的情況下，以報童模型為基礎，研究瞭資金收益對迴購契約的影響。繫統預期利潤變為與批髮價相關，利用拉格朗日方程求解瞭滿足零售商參與約束、同時使繫統和製造商預期利潤取得最大值的契約參數。與不攷慮資金收益情況下的供應鏈協調不同的是：訂貨批量大于相應批髮價下不攷慮零售商參與約束的最優訂貨批量；若零售商的保留利潤一定，則迴購價增大；迴購價可以大于批髮價，批髮價可以小于製造商的邊際生產成本。

The earning and cost of capital are often considered when the firms make their operation decisions. However, these factors are often not considered when studying supply chain contracts based on the newsvendor model. The capital earning rates of firms are different in selling cycles even though these rates are stable over a long period of time. For example, a manufacturer＇s capital earning rate is high when it urgently needs capital. This paper studies the influence of capital earning on supply chain contracts by discussing buy-back contracts.
