针对知识在知识合作网络中的传播特征,结合复杂网络理论,提出了一种网络上的知识传播模型.该模型将由知识扩散所引起的知识增长当作一种知识产品的合作生产,引入柯布-道格拉斯生产函数,并分别考察在个体不进行知识自我增长和进行知识自我增长情况下的知识传播.研究结果表明,在其它条件相同的情况下,网络的随机化程度越大.网络中知识的扩散速度越快,知识的分布越均匀。
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 CobbDauglas 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.
