由于宏观经济管理问题的复杂性，单纯按照控制理论组建解析模型是难以完成的，应以多级递阶系统理论为基本模式，而以应用系统分析作为宏观经济决策的基本方法。

Because of the complexity of macroeconomic management , it is not enough to establish analytic model purely according to control theory . It is suggested to use the theory of hierarchical multilevel systems as the fundamental pattern and use applied system analysis as the basic approach to macroeconomic decision .
