货币政策作用下物价指数波动的微分动力学模型分析

The Differential Dynamical Model of Price Fluctuant Under the Influence of the Monetary Policy of China

文章根据中央银行利用货币政策工具调节市场货币供给量的宏观经济调控策略建立了物价波动的微分动力学模型。通过对模型方程解的拓扑结构的剖析,应用数学软件绘制了模型解的拓扑结构曲线,并根据货币政策发生效力的时间滞后性,对社会消费品零售价格指数波动的一系列现象进行了系统的理论分析,揭示了我国货币政策作用下物价波动的内在原因和周期性规律。

According to the strategy of adjust monetary supply quantity by monetary policy, this paper established differentiable dynamical model of price fluctuant. By way of anatomy the topological structure of the solution of nonlinear differential equation, Paper protracted the curve of solution by means of Mathematics software. According to the time lag of the monetary policy that taking effect, Paper analysis the reason of fluctuant for retail price index.
