Abstract:

According to the propagation characteristics of knowledge in the collaborative networks of knowledge,a knowledge propagation model is proposed based on the complex network theory.In the proposed model,the Cobb-Dauglas production function is introduced to describe the increase of knowledge caused by knowledge diffusion,a kind of collaborative production of knowledge.The knowledge propagation with or without the self-improvement of agents are then considered,with the results indicating that,when other conditions remain constant,the diffusion speed and the distribution uniformity of knowledge in networks increase with the stochastic degree of networks.

Key words: complex network, knowledge propagation, knowledge collaborative production, small-world property
