Innovative user becomes more and more important in product innovation as a kind of new innovative resource. However, it is difficult to identify innovative user and evaluate real innovative user effectively during enter-prise practical innovative process. Aiming at these problems, Innovative User as a conception is proposed first in this paper. Then, a index system used to identify innovative user is constructed. At the same time, the Fuzzy Syn-thesized Evaluation Model of innovative user is created in AHP method. Finally, a case study is analyzed and the experimental result has proved the validity and feasibility of the proposed models and methods in this paper.
