摘要
本文对“产量陷阱”概念进行了修正,提出了“消费量陷阱”概念,证明了消费量陷阱与社会福利的变化方向相同,因而,存在消费量陷阱是实施非线性定价的必要条件。本文将全球通和神州行两种计费方式作为消费者面临的整体价格条件,定义了边际价格折线,进而定义了二阶非线性定价、三阶非线性定价;以消费量陷阱和边际价格折线为基础,定义了分界点、分界线,进而建立了线性最优定价模型、改进的二阶非线性最优定价模型和改进的三阶非线性最优定价模型。
This paper modifies the concept of output trap and presents a concept of consumption trap. It demonstrates that consumption trap and social welfare shift towards a same orientation, hence the consumption trap is the necessary condition for non-linear pricing. A marginal price curve is defined with the shenzhouxing service and GoTone service provided by China Mobile, as well as a second order nonlinear pricing and a third order non-linear pricing. Furthermore, author provides the definitions of demarcation point and demarcation line based on the consumption trap and the marginal price curve, and finally builds the models of linear optimal pricing, improved second order non-linear optimal pricing and improved third order non-linear optimal pricing.
