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。
Based on the literature on the relationship between relative price change and inflation in foreign countries, this paper first makes an empirical analysis of the relationship between China’s relative price change and overall inflation between January 2001 and February 2008. The results show that, In the sample period, there is a significant positive correlation between them, the inflation rate will be accompanied by a larger relative price adjustment; secondly, this paper studies the mechanism of relative price changes, that different types of products demand income elasticity, demand shock And supply shocks may cause changes in relative prices. Finally, the paper analyzes the significance of relative price changes to macroeconomic regulation and control.
