一类宏观动态经济系统的动力学模型

A Kind of Dynamical Models on Dynamical Macro-economic System

对基于消费、资本和货币的宏观经济动力学提出的模型及其动力学性质给予了相应的经济分析 ,获得了如下有现实意义的结论 :为保证经济的稳定运行 ,保持较低的货币增长率是必要的 ;人均消费水平过低不利于经济的稳定和快速发展 ;为保证我国资本市场的稳定与发展 ,应采取加快培养机构投资者、建立投资基金等措施 .另外 ,建立了一个关于人均货币持有量的动力学模型 ,讨论了人均货币持有量可能的动态性质 .

In this paper, the corresponding economic analyses are given to the economic dynamical model of consumption, capital and money and to its dynamical properties. Many conclusions with practical significance are obtained as follows: It is necessary for ensuring the economic running stability that the monetary growth rate is kept a lower level. The lower per capita consumption level is unfavorable to the economic stability and development with a high speed. Some measures such as cultivating the group investors, establishing inverstment fund should be taken for ensuring the stability and development of the capital market in China. Moreover, a dynamical model on per capita money holding is built, and the possible dynamical properties of per capita money holding are discussed.
