控制论在经济波动分析中的应用

Application of Cybernetics to Economic Fluctuation Analysis

为使一个宏观经济系统有较好的稳定性,运用Z变换对乘数加速权模型进行了分析.模型给出了3组参数,得到3种典型的经济波动方式:①波动振幅越来越小,逐渐趋于稳定状态;②保持了振幅和周期都一致的波动;③波动的振幅越来越大.在实际应用中可以利用这些参数值来分析某一宏观经济系统的稳定性,并据此做出适当的调整.

In order to enable macroeconomic system to have a better stability,Z transformation is employed to analyse the multiplier weighting number model.Three sets of parameters are obtained from the model,i.e.three typical economic fluctuation ways.Firstly,fluctuation amplitude becomes smaller and smaller and tends to be stable.Secondly,fluctuation is kept consistent in amplitude and cycle.Thirdly,fluctuation amplitude becomes bigger and bigger.In actual application,these parameters can be used to analyse the stability of a certain macroeconomic system so as to make proper regulation.
