摘　　要：本文采用了一种隐性增量谐波平衡法对周期性自发调节下非线性经济周期模型动力幅值演变进行了数值分析.收入周期解假设为由正弦与余弦函数的组成的傅里叶级数形式.当傅里叶级数选取适当的项数,所获得周期解与蒙特卡洛模拟值符合良好.A implicit incremental harmonic balance method was applied to analyze the dynamic amplitude evolution of the nonlinear business cycle model under periodic spontaneous adjustment.The periodic solution of income takes a form o f Fourier series consisting of sine and cosine functions.When the number of sine and cosine functions is adequate,the obtained periodic solution agrees well with the simulation result.
