中文摘要：

研究表明回购契约与收益共享契约具有等价性,然而二者却适用于不同的供应链。本文从提前期可控的视角并将供应链管理引入需求分布自由的市场环境,研究二者的适应性。首先构建一体化供应链系统的决策模型,基于模型推导其最优生产量和最优生产时点的存在性条件;然后分别以回购契约和收益共享契约作为激励机制,研究契约对单一供应商-零售商构成的二级分散供应链系统的适应性。结果表明,回购契约和收益共享契约均能协调供应链,但二者具有不同的适应性：当单位时间内边际生产成本增幅较大时,供应商偏好选择回购契约;提前压缩期越长,零售商越偏好选择收益共享契约。最后通过数值分析验证文章模型的有效性。

英文摘要：

In order to explain the phenomenon that the equivalence between the buy-back contract and revenue sharing contract does not agree with its adaptability in real life, in this paper, the adaptability of the contracts is studied under demand distribution free and controllable lead time. First of all, a model from the perspective of integrate supply chain is proposed, and then the existences of the optimum decisions including the optimum production quantity and the optimum amount of lead time from the integrate supply chain are proved. Second, the adaptabilities of the buy-back contract and revenue sharing contract under the decentralized supply chain are investigated, respectively. The analysis demonstrates that the contracts can coordinate the supply chain with demand distribution free and controllable lead time, but they have different adaptabilities. The supplier prefers to choose buy-back contract when the marginal cost of production changed is bigger, while the retailer prefers to choose revenue sharing when it has a longer lead time compression. Finally, a numerical analysis is given to demonstrate the validity and applicability of the model.
