基于流量、时间和费用的信息消费水平测度方法研究

信息消费水平的准确测度是促进信息消费的基础。在移动互联网蓬勃发展的时代背景下，首先从信息消费的过程、信息消费的多样性、信息化水平的提高三个方面分析了综合利用流量、时间和费用三项指标进行信息消费水平测度的必要性；接着在信息消费具有惯性的假设下，利用固定权重和可变权重，构建了基于流量、时间和费用的信息消费水平测度模型，证明了该模型具有非负性、传递性、连续性和可加性；最后通过实证调查验证了所构建模型的正确性。实证结果表明：流量、时间和费用均是测度信息消费水平的重要指标；利用单一费用指标测度的信息消费水平与综合利用流量、时间和费用三项指标测度的信息消费水平有显著差异，而且会明显低估真实的信息消费水平。

On the measurement of information consumptionin terms of flow,time and cost

The accurate measurement of information consumption is the basis for promoting information consumption. Based on the rapid development of mobile Internet, this paper analyzes the necessity of measuring information consumption in terms of the indexes of flow, time and cost from three aspects: the process of information consumption, the diversity of information consumption and informatization level; Under the assumption that information consumption is inertial in a certain period, and based on fixed weights and variable weights, a measurement model is constructed by using the indicators of flow, time and cost, and the measurement is proved to be nonnegative, transitive, continuous and increasable; Besides, a survey based on this model is analyzed. The results show: flow, time and cost are important indicators for measuring information consumption; an information consumption measured with the single cost indicator is significantly underestimated, and has a significant difference from the measurement in terms of three indexes of flow, time and cost.
