Abstract: Based on the monthly Chinese CPI data from 1990 to 2013, this paper uses the quantile autoregression model proposed by Koenker and Xiao (2006) and quantile unit root tests method proposed by Koenker and Xiao (2004) to research the asymmetric characteristics of Chinese inflation persistence. By means of the research to persistence parameters, unit root test and half-life in different quantiles, this paper gets a very robust result. The result shows that Chinese inflation persistence has significant asymmetric characteristics; the inflation persistence before 1998 is significantly less than the inflation persistence after 1998; the inflation persistence in low inflation is significantly less than the inflation persistence in high inflation.

摘要： 本文基于1990-2013的中国月度CPI数据，使用Koenker and Xiao(2006)提出的分位数自回归模型以及Koenker and Xiao（2004）提出的分位数单位根检验，对中国通货膨胀持续性的非对称特征进行了研究。通过分析不同分位点上的持续性系数、单位根检验和半衰期，本文得到了非常稳健的结果：中国的通货膨胀持续期存在明显的非对称特征，1998年之后通货膨胀持续性要显著低于1998年之前的通货膨胀持续性；低通货膨胀水平上的通货膨胀持续性要显著低于高通货膨胀水平上的持续性。
