研究通货膨胀的波动性特征,对于货币当局治理通货膨胀以及公众形成合理预期具有重要现实意义。因此,运用AR(4)-GARCH(1,1)模型族与SV模型族,对我国通货膨胀的波动性特征进行分析。检验结果表明,我国通货膨胀的波动具有聚集性、持久性、非对称性以及“溢出效应”等特征。为此,货币当局应当贯彻执行稳健的货币政策,并通过提高政策的透明度,使公众形成合理预期,以更有效地实现稳定物价的政策目标。
研究通貨膨脹的波動性特徵,對于貨幣噹跼治理通貨膨脹以及公衆形成閤理預期具有重要現實意義。因此,運用AR(4)-GARCH(1,1)模型族與SV模型族,對我國通貨膨脹的波動性特徵進行分析。檢驗結果錶明,我國通貨膨脹的波動具有聚集性、持久性、非對稱性以及“溢齣效應”等特徵。為此,貨幣噹跼應噹貫徹執行穩健的貨幣政策,併通過提高政策的透明度,使公衆形成閤理預期,以更有效地實現穩定物價的政策目標。

Study on the volatility of inflation has very important practical significance to inflation governance by the mone- tary authorities and formation of reasonable expectation by the public. Then, the article uses AR(4) -GARCH(1,1) models and SV models to analyze the volatility of inflation in China. The empirical results show that, China's inflation volatility has the characteristics of clustering, durability, asymmetry and the "spiUover effect". As a result, in order to achieve policy objective of price stability more effectively, monetary authorities should implement a sound monetary policy and increase the transparency of policy to enable the public to form reasonable expectations.
