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.
