| 摘 要： | 在阐述知识类信息消费边际效用的相关理论的基础上，论述知识类信息消费边际效用变化的基本规律，
分析不同认知水平消费者知识类信息消费边际效用的差异。认为知识类信息消费的边际效用符合先递增后递减的规律；与较低认知水平消费者相比，较高认知水平的消费者边际效用增加速度较快，边际效用最大值更大，但边际效用下降的速度也较快。

| Abstract: | On the basis of treating the correlative theory of the marginal utility for knowledge-information consumption , this paper discusses the basic law of the marginal utility for knowledge-information consumption, and analyses the difference of the marginal utility for knowledge-information consumption in consumers whose cognitive level are different. It thinks that the law of marginal utility for knowledge-information comsumption is firstly increasing then decreasing. And the authors suppose that the increased speed of marginal utility for high-cognitive consumers is faster than low-cognitive consumers, and also the maximum marginal utility is greater, but the deceased speed of marginal utility is more quickly. |
