摘　　要：针对具有服务差异的有限理性双寡头制造商的竞争策略选择问题,运用Cournot模型、考虑服务竞争,建立了具有服务差异的双寡头制造商有限理性重复博弈模型,从系统动力学演化的角度对模型进行了均衡分析,并通过数值模拟分析了具有服务差异的双寡头制造商的重复博弈过程,指出了寡头理性和服务水平对双寡头制造商收益的影响。研究结果表明,如果双寡头制造商理性有限,双寡头竞争进入混沌无序状态,那么服务水平与寡头利润不具有绝对的正相关关系;具有服务差异的有限理性双寡头制造商在动态竞争中应当在综合分析寡头双方服务水平和对方寡头产量竞争策略的基础上严格控制产量调整速度,避免过度竞争,双方共同维持系统稳态均衡。The dynamic competition process of duopoly manufacturers with bounded rationality and service differentiation is addressed in this paper. With service competition considered, by using Cournot duopoly model, a repeated game model is established for the problem. Based on the model, balanced condition is analyzed in view of system evolution. With the balanced condition, a numerical simulation is performed. By numerical simulation, the influence of duopoly rationality and service level on duopoly manufacturers is analyzed. It shows that when the competition between duopoly manufacturers with bounded rationality enters a chaotic state, level of service and duopoly profit are not absolutely positively correlated. The best choice for duopoly manufacturers is to strictly control the output adjustment speed based on the comprehensive analysis of duopoly manufacturers＇ service levels and output competition strategy such that excessive competition is avoided and a system steady equilibrium is maintained.
