寡头竞争模型的拓展研究

Research on the Expanded Oligarch Competition Model

文章在常用的寡头竞争模型中引入时间差带来的影响参数,从而形成了拓展的寡头竞争模型,通过计算分析,分别得到该模型下的均衡产量或均衡价格;同时,详细研究时间差带来的价格和成本变化对模型均衡结果特征及两个模型对比关系的影响,形成汇总表;最后,给出一个简单的案例进行实证研究以解释其应用意义。

The influence parameters induced by the time-interval were introduced to the normal oligarch competition model in this article, and formed the expanded oligarch competition model. Through calculating and analyzing, equilibrium quantity or equilibrium price could be obtained in this expanded model. At the same time, the influences that the price and cost varieties, induced by time-interval, had thrown to the model equilibrium results＇ characteristics and the contrast relationship of the two models were researched in depth, and collection sheet was posed. At last, a simple case was presented for case study and explaining the expanded model＇s application significanee in this paper.
