中国物价总指数变动中的相对价格调整及其宏观调控含义

Regulation of Relative Price in the Variability of China General Price Index and Implications of Macro-economy Control

在对国外相对价格变动与通货膨胀关系研究的文献基础上,本文首先对2001年1月至2008年2月间的中国相对价格变动与整体通货膨胀之间的关系进行了实证分析,结果表明,在样本期内,它们之间存在显著的正相关关系,通胀率上升会伴随着相对价格较大地调整;然后,本文研究了引起相对价格变动的机制,认为不同类别产品的需求收入弹性、需求冲击与供给冲击都可能引起相对价格的变化;最后分析了相对价格变动对宏观调控的意义。

The relationship between China relative price variability and inflation is analyzed in this paper from Jan.2001 to Feb.2008 in view of foreign literatures,the result shows that there is positive relationship,and the relative price is variable when inflation is rising.Then,the mechanism of relative price variability is studied and hold that the relative price variability could stem from all of the elasticity of different goods demand to income,demand shock and supply shock.In the end, the paper points out the implication of relative price variability for macro-economy control.
