摘要
本文以宏观经济学中关于国民收入、消费、投资、政府支出四者关系的动态乘数——加速数模型为基础,应用现代控制理论中的状态空间法把这一动态经济系统描述成状态空间形式,并对其进行了稳定性、能控性、能观性的理论分析,在此基础上阐述了如何改善系统的稳定性.最后,用实例对此理论分析给予验证.
This paper considers the multiplier-accelerator model on national income, consumption, investment, government expenditure in macroeconomics as the foundation,applies the state space method in modern control theory to describe this dynamic economic system by a state space formula and theoretically analyses the stability, controllability, observability of the system.On this foundation, how to improve the stability of the system is expounded, at last, the theoretical analysis is verified with a simple example.
