摘　　要：基于企业社会责任中的消费者剩余,企业1采取有限理性期望,企业2采取朴素期望,建立双寡头动态博弈模型.讨论了均衡点的存在和稳定性条件,并通过数值模拟得出:适当的消费者剩余参数更符合市场竞争,同时较小的调整速度更有利于系统的稳定.因此,企业选择合适的参数有利于企业在市场中更加长久的发展.Based on consumer surplus in corporate social responsibility,firm 1 adopts bounded rational expectation and firm 2 adopts naive expectation,and a duopoly dynamic game model is established.The existence and stability conditions of the equilibrium point are discussed,and numerical simulation shows that appropriate consumer surplus parameters are more in line with market competition,and the smaller adjustment speed is more conducive to system stability.Therefore,the choice of appropriate parameters is conducive to the long-term development of enterprises in the market.
