由于乘数加速模型的差分方程组求解困难深圳翻译公司, 所以经典宏观经济模型对经济参数的影响难以做深入、全面分析, 降低了模型的精确度。本文提出以信号与系统的理论分析凯恩斯提出的宏观经济经典模型, 从系统角度对模型进行分析,可以很清晰的分析出系统参数和输入信号对宏观经济运行的影响。通过分析系统结构和系统响应特性, 确定系统参数对于经济运行情况的影响。计算结果表明这一新方法克服了传统的直接利用矩阵原理对模型进行分析的一系列弊端, 提高了模型精度。研究结果可以为广大决策者提供参考。
As it is difficult to solve the system of difference equation of multiplier-accelerator model, it is difficult to thoroughly and comprehensively analyze the effect of typical macro economic model on economic parameter, and the accuracy of model is diminished.   In this paper macro economic typical model proposed by Keynes is analyzed by signals and system theory, model is analyzed from a systemic perspective, so effect of system parameter and input signals on macro economic operation can be clearly analyzed. Through analysis of system structure and system response characteristic, effect of system parameter on economic operation can be determined. Calculation result shows that series drawbacks which occur while model is directly analyzed by matrix theory in traditional way is conquered by this new method, and accuracy of the model is improved. Deciders can refer to the study result. 
本文在原有模型的基础上, 引入信号与系统的概念和思想。将模型看作一个系统, 将上一年的经济运行结果看作系统的输入信号, 将当年的经济运行情况看作是系统对输入信号的响应。通过 Matlab 软件建立模型系统结构, 进行计算机模拟仿真, 对模型进行了更加深入的分析, 得出模型参数对经济系统运行结果的影响德语翻译
In this paper, on the based of the original model, concept and thought of signals and system is introduced.  Model is regarded as a system, economic operation result in the previous year is regarded as input signals, and economic operation condition in the current year is regarded as response of system to input signals. Model system structure is established through Matlab software to carry out computer analog simulation; so as to thoroughly analyze the model, effect of model parameter on economic system operation result can be got.
