The Research About Supply Chain Information Differentiation Sharing

Based on the related theory of supply chain information, this paper defines differentiation information sharing in supply chain information. And this paper also discusses the issue that how to control the right of SI and realize sharing stimulation in order to realize SI (supply chain information)differentiated sharing. For this purpose, This paper discusses and analyzes the problem about SI classification and supply chain partnership classification. This paper divides the index of supply chain information into three factor: information sensitivity; information efficiency; information cost. Each factor has its own index system, and this paper bulid the index system of supply chain partnership. Concerning the SI classification, firstly utilizing vague general evaluation to divide supply chain information into three classes separately according to information sensitivity and information efficiency. Then using the cost function to divide supply chain information into three classes. So there are 27 kinds of supply chain information that can be divided into 7 levels by marking. This paper also divides supply chain partnership into 4 classes through Grey Theory. And formulating the different level of supply chain information according to different partnership in order to realize the differentiation sharing of supply chain information and the security control. Finally this paper elaborates the content of the information incentive mechanism. And establishing the related model to analyze the game relation between principal and agent under visible and invisible condition.
