摘要/Abstract

摘要： Building on the existing symmetric quantization model of the dynamic Cournot duopoly game (CDG) with asymmetric information, we extend it to an asymmetric quantization model and study the stability of the quantum Bayesian Nash equilibrium (QBNE) under heterogeneous expectations. We analyze the influence of various parameters on the stability of QBNE, with a particular focus on the impact of the parameter $\alpha$ on system stability. The results show that when $\alpha < 1$, under the same parameters, the quantum strategy of the asymmetric quantization model is more favorable for stabilizing the market. However, when $\alpha>1$, the quantum strategy of the symmetric quantization model is more conducive to stabilizing the market.
