现有测度通胀惯性的常用模型是仅含自身滞后因子的自回归模型,该模型不能有效反映通胀预期和波动性对通胀惯性的影响。本文在自回归模型基础上,构建了一个包含通胀惯性、学习型预期和波动性特征的通胀动态模型。该动态模型从均值和波动项两个方面反映了我国通胀水平的动态变化趋势和特征。针对上述模型不能有效反映通胀状态体制变化的缺点,本文还引入Markov机制转换模型来测度我国通胀水平的状态转移特征。利用分位数回归方法下的自回归模型、本文构建的通胀动态模型以及Markov机制转化模型实证研究了我国通胀的动态特征。分析表明:我国通胀水平具有较强的惯性特征;通胀惯性的形成机理比较复杂,学习型预期只能部分解释通胀惯性;通胀水平的状态转移时间比较长;通胀水平与其波动性有着正向的关系。
現有測度通脹慣性的常用模型是僅含自身滯後因子的自迴歸模型,該模型不能有效反映通脹預期和波動性對通脹慣性的影響。本文在自迴歸模型基礎上,構建瞭一箇包含通脹慣性、學習型預期和波動性特徵的通脹動態模型。該動態模型從均值和波動項兩箇方麵反映瞭我國通脹水平的動態變化趨勢和特徵。針對上述模型不能有效反映通脹狀態體製變化的缺點,本文還引入Markov機製轉換模型來測度我國通脹水平的狀態轉移特徵。利用分位數迴歸方法下的自迴歸模型、本文構建的通脹動態模型以及Markov機製轉化模型實證研究瞭我國通脹的動態特徵。分析錶明:我國通脹水平具有較彊的慣性特徵;通脹慣性的形成機理比較複雜,學習型預期隻能部分解釋通脹慣性;通脹水平的狀態轉移時間比較長;通脹水平與其波動性有著正嚮的關繫。

Autoregressive model only containing own lag factor is commonly used to measure inflation persistence, but the model can not effectively reflect the influences of the inflation expectation and volatility on the inflation persistence. Based on an autoregressive model, a dynamic model of inflation containing inflation persistence, learning expectation and fluctuating characteristic is built. The dynamic model reflects the changing trends and dynamic characteristics of the inflation level from the mean and volatility. For the above models can not effectively reflect the institutional change of inflation, this paper also introduces markov switching model to measure the state transition characteristics of the inflation level. Empirical studies of the dynamics of inflation in China are given respectively based on the autoregressive model under quantile regression, the dynamic model built in the paper and the markov transformation mechanism model. Analysis shows that: Chinese inflation has strong persistence characteristics; The formatting mechanism of inflation persistence is complex in China, and learning expectations can only partially explain inflation persistence; The state switching time for the inflation level is long; Chinese inflation and its volatility has a positive relationship. Finally, some specific recommendations are given.
