英文摘要: |
In order to further explore how memory and demand function form affect the dynamic evolution of Cournot
game, we construct the dynamic evolution model of Cournot duopoly with memory and general isoelastic demand under Gra⁃
dient adjustment mechanism and local monopolistic approximation adjustment mechanism by using nonlinear dynamics the⁃
ory, and obtain the Nash equilibrium solution. The influence of memory and elastic coefficient on the stability and nonlinear
dynamic evolution of Nash equilibrium point are analyzed. Through theoretical derivation and numerical simulation, it is
found that the increase of memory plays a stable role in the Cournot Nash equilibrium of output decision, while the increase
of elastic coefficient promotes the formation of chaos in the Nash equilibrium. The opposite effect of the two on the Nash
equilibrium results in the complex properties of the Cournot Nash equilibrium. |
