The traditionary point considers the stratagem relationship of SCP (supply chain partnership) which can be strengthened mutual relationship with supplies by holding the same stratagem to enhances performance of supply chain management. At present, many scholars have studied this relationship more and more, but much papers are not satisfyingly explain complex relationship with supplies. Because the more complex and the more dynamic the market changes, the more flexile the custom demand. So the tradition point faces new challenge, which relationship with supplies not only has the same stratagem based on long-profit but also has more flexile for adapting demand of market. In this paper, we use theory of biology and complex adaptive system (CAS), points out the new relationship model called co-evolution relationship of SCP. 展开更多
