耐用品动态古诺模型的建立及分析

Building and analysis on a dynamical Cournot model with durable goods

依据耐用品的市场容量随着时间发生变化的特点,对多个企业同时博弈的动态古诺模型进行修正,建立了适用于耐用品市场的动态古诺模型,并得到新的产量均衡解.通过与合作情形下的最优产量解的比较与分析,得到非合作情形下的产量均衡解和合作情形下的最优产量解都随着阶段数的增加而单调下降,并且前者依旧劣于后者等结论.

Taking into account the change of the market capacity with time for the durable goods the decision stage, in this paper, proposes a modified dynamical Cournot model with multi-firms＇ simultaneous game. We investigate this model and obtain a new equilibrium solution. Then, through comparing and analyzing this solution with the cooperating solution, we obtain some important results： that both the above two solutions are decrease with the increase of the number of game stages, and the equilibrium solution is inferior to the cooperating one.
