Abstract: Influencing factors of knowledge creation capability from five different aspects are proposed through analyzing process of knowledge creation aimed at promoting the enterprise knowledge creation capability (KCC). Then an analysis method based on fuzzy set theory and fuzzy clustering approach to analyze enterprise KCC is proposed. This method can help organizations extract the key attribute set of influencing factors then deduce the key influencing factors which affect the creation capability mostly. Organizations can adjust their strategies of knowledge management (KM) and knowledge creation according to the analytical result to improve its knowledge creation capability and gain core competence. Finally, an application case is provided to illustrate the application of the presented method.
