摘要
根据Klecki思想,对投资过程中具有常数时滞的一类动态宏观经济模型进行了讨论.通过选择时滞作为Hopf分歧参数,当时滞经过临界值时周期行为产生.并用数值例子解释了理论结果.
This paper discussed the dynamic macroeconomic model with constant time delay in investment processes according to Kalecki＇s idea.By choosing time delay as the Hopf bifurcation parameter,it is found that a periodic behavior occurs when time delay takes certain critical values.Numerical simulations were then provided to verify the theoretical results.
