寡头垄断、非线性定价与非对称价格规制

The Duopoly,Nonlinear Pricing and Asymmetric Price Regularity

本文系统研究了非对称寡头垄断行业的价格规制问题。在非对称双寡头垄断市场结构的假设下,本文首先分析了双寡头企业的非线性定价行为与市场均衡。双寡头企业都基于各自边际成本的最优非线性价格,以及实现福利最大化的价格和竞争性均衡价格,其价格套餐都会发生交叉,进而产生市场分割。以此为理论基础,在综合考虑价格规制目标、可实施条件和行业现状的基础上,本文给出了非对称双寡头垄断行业价格规制的总体思路设计:在垄断行业引入竞争机制改革的过渡时期,应采取非对称价格规制,双寡头企业的规制价格套餐交叉导致的市场分割,会有利于有效竞争的市场格局最终形成。

This paper systematically studies the price regulation of asymmetric monopoly industies.Under the assumption of the asymmetric duopoly market structure,this paper firstly analyzes the duopoly nonlinear pricing and market equilibrium.The duopoly enterprises carry out the best nonlinear price based on their marginal cost,price for best welfare and competitive equilibrium price,the cross of the price package occurs and then the market is segmented.Taking this as a theoretical basis,based on the comprehensive consideration of objective of price regulation,implemented conditions and industry status,this paper gives a design of the general idea about the price regulation of asymmetric monopoly industries： in the transitional period of introduction of competition by monopoly industries,asymmetric price regulation should be implemented,and the market segmentation resulting from the package of price regulation of duopoly enterprises helps the final formation of effective competitive market.
