Based on the literature of dynamic business cycle model, this paper studies the impact of ( sum of self - investment and self - consumption) on economy when it proves to be random function interfered by random. The application of multiple scales results i%在文献[1]给出的动态经济周期模型的基础上,研究当O*(t)(白发投资与自发消费的总和)为随机外力干扰的随机函数时对经济的影响,应用多尺度法及文献[7]求出了一阶近似解及系统的稳态响应,并分析了参数和随机激励的幅值对经济系统的影响.讨论了非零解的稳定性以及非零解稳定的充要条件,得出当随机激励的带宽γ较小时,系统仍会出现多值现象.
