基于经济系统内生因素造成的经济系统自身不确定性分析,改进了Benhabib and Farmer的不确定模型.在此基础上,通过动态最优化的方法,得到了一个二维系统,并分析了系统的稳定性,结果表明政府的过度投资将导致经济系统发生不确定性.
Based on the Benhabib and Farmer's indeterminacy model,an improved model on two-dimensional system was presented by dynamic optimization.Then the stability of this system was analyzed.Finally,it proved that the government's overinvestment would cause the indeterminacy of economic system.
