摘    要:本文在区分居民通货膨胀预期和经济学家通货膨胀预期的基础上,研究通货膨胀预期形成和锚定的特点,发现经济学家通货膨胀预期呈现不规则的正态分布,往往在通货膨胀实际值较低时更多的经济学家做出偏高预期.居民通货膨胀预期显示低收入阶层对物价上涨更为敏感,大城市居民通货膨胀预期最敏感.总体如果半数以上的人认为物价上涨,则出现恶性通货膨胀的概率增加.发现居民物价预期指数是通货膨胀的格兰杰成冈,但经济学家通货膨胀预期却不必然导致通货膨胀发生.国际比较发现英国居民物价预期指数显著高于中国.锚定通货膨胀预期的关键是防止通货膨胀预期加速形成,防止中央银行陷入通货膨胀预期陷阱,为此需要单一化中央银行职责,建立通货膨胀预期中期监测机制,竖立中央银行反对通货膨胀的信任度.

关 键 词:通货膨胀  预期形成  预期锚定  通货膨胀预期陷阱
