The effect of each factor was examined by classifying the preceding factors of knowledge-sharing into several categories such as personal factor, organizational factor, and technical factor. The results of study suggested that the pleasure of knowledgesharing, support of executives, reward of organization, and utilization of system had a positive impact on the knowledgesharing. However, it was found that the self-efficacy did not have significant effect on the knowledge-sharing.
