Abstract: Aiming at the problem of important degree evaluation for innovative customers in collaborative product innovation,a novel method was put forward based on complex networks theory.To represent innovative customers and their relationships,an undirected weighted network model of customer collaborative product innovation was established.The knowledge level was used as quantitative index of correlation strength to delete the change degree of network efficiency before or after customer node,which could taken as the evaluation criteria of innovative customers importance.On these bases,the method and procedure to calculate the importance were analyzed.Through the example of a complete collaborative innovation task,the feasibility and rationality were demonstrated.

Key words: collaborative products innovation, innovation customer, importance, complex networks, network efficiency
