中文摘要：

供应链的主要特征之一就是企业群凝聚为长期的战略合作体，形成一种类似生态网络的战略网络结构．协调企业个体间以及与网络整体间的利益关系常表现为对供应链中间产品的定价上，所以设计动态利益调节机制，可使各合作伙伴的运作更加符合整体利益的最大化．文中针对供应链网络结构的特征，应用信息熵原理及生态网络理论，定义供应链产品流动的生态网络熵聚合度，建立供应链产品动态定价的生态网络熵模型，描述供应链产品中间价格波动的动态过程，给出熵模型收敛的一般性条件及其均衡解，证明在一定条件下供应链各合作伙伴的利益可以通过动态价格波动调整过程达到均衡，实现供应链总体利益的最大化．最后，通过一个具体算例说明动态价格波动熵模型的可行性和实用性．

英文摘要：

A main characteristic of the supply chain is usually shown as long-term strategic cooperation union of firms, a strategy network system, which is similar to eco-network is formed. Coordination the interest relationship between partners and the entire supply chain is often represented by pricing intermediate product of the supply chain, so dynamic interest coordination mechanism must be redesigned and partners an act in ways closer to what＇s best for the entire supply chain. In this paper, in order to gibe characteristic of the supply chain network, an entropy model with dynamic price of the intermediate product and accordance output of the productivity. Based on the coo-network theory and entropy theory, a definition on extent of polymerization of the supply chain network is given. The general conditions of convergence and its proofs and balancing solution of the entropy model are given. Finally, an example is give to show the feasibility and availability of the developed model.
