摘　　要：在分析产品属性信息和信息不对称定义的基础上 ,比较完整地提出了可度量的信息不对称度的定义 .对不同生命周期产品的信息不对称度变化的基本规律进行定性分析 ,得出了信息不对称度逐步降低的结论 .Based on the analysis of the attribute information of a product,the definition of the degree of information asymmetry was put forward. How to calculate the degree of information asymmetry was illustrated with an example. The general changing rules of the degree of information asymmetry about four lifecycles of a product were given. It was concluded that the degree of information asymmetry reduced gradually.

关 键 词：信息不对称 信息不对称度 规律
