Abstract:

The knowledge diffusion model proposed by Professor Xu Yu is analyzed and the model follows a logistic increment rule that is applicable to the condition of enterprise knowledge accruement. However, when the effort factor of knowledge diffusion by the managers in corporation is considered, the model cannot explain the knowledge diffusion rule. From the angle of thought, the mechanism in the course of knowledge diffusion is analyzed and hereby the knowledge diffusion model is modified. The modified model concerns the factor of manager’s effort and the knowledge diffusion of enterprises follows the exponential increment law when considering the effort; however the diffusion follows the logistic increment law when the effort is given up. Therefore there is a critical point in the course of knowledge diffusion and the point fluctuates with the different of knowledge property and function.

Key words: corporation knowledge, knowledge diffusion, exponential increment, diffusion model
