使用两阶段博弈模型对比了数量竞争(Cournot)和价格竞争(Bertrand)下的均衡质量。双寡头竞争情况下的理论分析结果显示,不同的市场条件具有不同的对比结果,而多寡头情况下的算例分析则揭示Cournot竞争比Bertrand竞争具有更高的均衡质量。
Comparison of cournot competition and bertrand competition has been widely undertaken in the academic literature. In recent years, production quality has played a more significant role in increasing market competition. It is especially important to understand how quality is influenced by different types of competition. This paper presents a comparing analysis of equilibrium quality in cournot competition and Bertrand competition through the two-stage game models. It is found that different conditions lead to dif- ferent results in duopoly situation, while numerical computation releases that quality in cournot competition is higher than that in bertrand competition in oligopoly market.
