知识类信息消费的边际效用分析

An Analysis of Marginal Utility for Knowledge-Information Consumption

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。

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 consumption 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.
