Dynamic Analyses of the Impact of Macroeconomic Variables on Prices

针对当前我国经济运行中物价水平变动的影响因素及其存在的问题,通过引入脉冲响应函数和方差分解方法,向量自回归模型可以从客观上分析宏观主要经济变量对物价的动态冲击和影响。实证结果表明,经济变量对物价的影响各异且存在着一定的时滞效应。因而,有关部门在不同时期宜采取相应不同的调控措施,以维持物价的稳定和经济的持续发展。This paper is concerned with the factors in price fluctuations in current economic operations and their related problems in China.It proposes that it is possible to analyze quantitatively the dynamic impact of major macroeconomic variables on prices by creating the VAR model and its Impulse Response Function(IRF) and Variance Decomposition(VD).The results show that each economic variable influences the price in its own way,and that there exists a lagged effect to some degree.It is suggested that various regulatory measures be taken in different periods to maintain price stability and sustained economic development
