中文摘要：

为优化季节性商品两级供应链的性能，引入收益分享契约。供应商通过分享零售商的销售收入，可以有效地降低批发价。吸引零售商订购更多的商品，并且供应商通过调节批发价和收益分享因子可以在协调供应链的前提下任意划分供应链的总利润。讨论了收益分享契约在供应商管理库存模式下的应用，找到了优化供应链性能的决策集。进一步分析了批发价为0时供应链性能的优化策略，通过引入剩余补贴因子实现了在协调供应链的同时任意分配供应链的总利润。最后用数值算例对结论进行了说明。

英文摘要：

To improve the performance of a two echelon supply chain facing a newsvendor problem, a revenuc-sharing con tract was introduced. The wholesale price was decreased by sharing sales income so as to attract more product orders. By adjusting the wholesale price and the revenue-sharing factor, the supplier could achieve two objectives： 1 ） the supply chain was coordinated and 2） the total profit of the supply chain could be arbitrarily divided between the supply chain members. The application of the revenue-sharing contract under a vendor-managed inventory （VMI） mode was further discussed, and the decision sets were obtained to optimize the performance of the supply chain. The supply chain optimization tactics were put forward while the wholesale price equaled to zero, and above two objectives also could be achieved by introducing a sur plus subsidy factor. Finally, conclusion was illustrated by numerical examples.
