非线性定价下的双头垄断企业行为分析

本采用了泰勒尔的消费基本效用函数模型，从消费剩余效用最优化的角度分析了双头垄断企业的市场行为，得出了如下结论：企业非线性定价条件下，任何类型的消费都存在一个最优消费数量，双头垄断竞争有助于扩展市场，提高产品质量，降低产品价格，但双头垄断在非线性定价下的最终市场均衡是达到完全垄断，而政府管制和赤可以防止完全垄断的形成，等等。

The Actions of Duopoly Under the Nonlinear Pricing

We use the Jean Tirole's basic customer's Utility function model, analyze the actions of duopoly by optimizing the customer's utility, and get the result: under the nonlinear price of duopoly, there exists an optimal consumption to maximize the utility for every kind of customer; the duopoly competition can expand the market,and prove the quality and lower the price; but the duopoly market competition balance will be a monopoly market, so the government's measure can prevent the monopoly, and so on.
