把针对供应链契约的研究从传统的一对一结构扩展到供应链网络结构。充分考虑了网络中的纵向竞争与横向竞争,采用计算实验方法研究了竞争环境下回购契约对供应链网络的协调机制。实验结果表明,当市场需求与零售价格相关且零售价格由零售商自主决策时,回购契约虽不能完美协调竞争环境下的供应链网络,却能够在一定程度上改善供应链绩效并增加系统收益稳定性,网络中各主体均有采用回购契约的动机。
This paper expands the supply chain structure for contracts researching from the traditional one to one to the supply chain network.Fully considering the vertical and horizontal competition in the network,it studies the coordination mechanisms of buy-back contract for supply chain network in competitive environment with the computational experimental method.The main conclusions are: when the demand associates with the retail price decided by the retailer independently,perfect coordination can not be obtained for the buy-back contract of supply chain network in competitive environment,but it is able to improve supply chain performance and increase the stability of benefit to some extent.The members in network all have incentives to use buy-back contract.
