摘　　要：主要研究具有部分信息的古诺-伯川德双寡头模型.公司1采取的是产量调整,公司2采取的是价格调整.主要通过数值和数值模拟的方法研究了不动点的稳定性,从中发现只有一个Nash均衡点存在,并重点研究了在Nash均衡点处的性质并且讨论了产量调整速度与价格调整速度对经济发展的影响.This paper mainly studies the Cournot-Bertrand duopoly model with partial information.Company 1 adopts the output adjustment and company 2 adopts the price adjustment.In this paper,we mainly study the stability of the fixed point by numerical and numerical simulation methods,finding that only one Nash equilibrium exists.The paper focuses on the nature of the Nash equilibrium point and discusses the impact of the speed of production adjustment and price adjustment on economic development.
