生产不确定下动态双寡头竞争策略研究

Research on dynamic duopoly competition strategy under uncertain yield

目的为古诺型企业在生产不确定下制定最优目标产量提供理论依据。方法利用随机产出比例模型,构建随机产出下的古诺双寡头动态对称竞争模型和动态不对称竞争模型,通过求解相应雅可比矩阵的特征值得出结果。结果得出双寡头在信息对称和信息不对称2种情况下的均衡目标生产策略和期望市场产出。结论说明了动态系统的稳定性和期望市场产出与产出风险系数之间负相关。

Purposes—To provide a theoretical basis for the formulation of optimal target production under uncertain yield of Cournot-type enterprises.Methods—The stochastic output ratio model is used to construct the Cournot duopoly dynamic symmetric competition model and the dynamic asymmetric competition model under stochastic output,and the results are obtained by solving the eigenvalues of the corresponding Jacobian matrix.Result—The equilibrium production strategy and the expected market output of the duopoly in the case of information symmetry and information asymmetry are obtained.Conclusion—The dynamic system is stable,and there is a negative correlation between expected market output and yield risk coefficient.
