Kaleski商业循环模型及其改造

作者在文献1]中提出了经济系统中引入投资决策方程改善动态品质的一般概念,在此基础上,本文探讨Kaleski模型进一步改造的必要性,使其理论分析的结果吻合资本主义扩大再生产的实际进程,并研究改善Kaleski模型动态品质的实际途径.文中应用Z变换理论来处理离散时滞系统,并给出了计算实例,避免了求解超越方程的麻烦.当系统阶次越高,本文建议的方法越能显示其优越性,且便于用微机来研究动态问题.本文还指出了原Kaleski模型中理论解中的错误.

KALESKI BUSINESS CYCLE MODEL AND ITS REFORM

Introducing investment decision equation to improve dynamic behaviour 19 proposed by authors^1]. Based on the proposal, we discuss the necessity of further reform of Kaleski business cycle in order that the result of theoretical analysis coincides with the actual expanded reproduction process of capitalism. We also study the measures of improving dynamic behaviour of the model. In the analysis of discrete system with time delay, Z-transform is utilized, some numerical examples calculated, and the trouble caused by solving transcendental equation is avoided. As the order of characteristic equation becomes higher, the method proposed in this paper shows better its advantages. And microcomputers are found to be the suitable tools for researching dynamic problems. The wrong theoreticle solution of Kaleski model is found out and corrected in this paper.
