摘要
考虑到多阶段的博弈过程需要涉及长期利润的特点,建立了两个以长期利润为目标的多个耐用品企业同时博弈的动态古诺模型(长期非合作模型和长期竞争均衡模型)。通过对多个模型求解结果的比较与分析可知,长期竞争均衡模型下的市场竞争最为激烈,但还是优于短期竞争均衡模型;当然,它依旧劣于非完全竞争情形下的长期非合作模型和长期合作模型。
The Cournot model is one of basic economic models. After years of continuous development and improvement, the model has become one of the most widely applied models used to analyze the behavior of every production enterprise in the oligopoly market. The Cournot model is also named dynamical Cournot model because it can be used to study the output games among monopolists over a period of time. In the market of special ~turable goods, the implicit assumption of the unchanged market capacity in traditional, dynamical Cournot model has not been established. This paper supposes that capacity in a new stage could be calculated by first deducting the sales amounts of products sokJ in the previous stage, and then adding the newly increased market derived from the waste of sold products because of technological change, lifestyle changes, etc. By applying the dynamic Cournot model to analyze the durable goods market, this paper assumes that all companies primarily pursue immediate self-interest in the production process. However, this model also suggests that an effective production strategy should not only involve immediate profit, hut also consider profit in other stages or the overall profit of the whole game in the multiple-stage game process. This paper applies the dynamiealCournot model in analyzing several durable goods＇ enterprises in the same game, and builds two new models to maximize the long-term profit. These two models are long-term no cooperation model and long-term competitive equilibrium model. The goal of the former model is to maximize profit for an enterprise, and that of the latter model is to achieve the same objective by considering the constraint of inverse inference. The latter model has the advantage of obtaining the Nash equilibrium result. This paper compares and analyzes the production solutions among these models, including the proposed long-term no cooperation model, long-term competitive equilibrium model, short-term competition equilibrium model, short-term cooperation model, and long-
