利用马尔科夫区制转移模型来具体刻画和分析我国通货膨胀率过程的时间动态轨迹,检验结果表明,我国通货膨胀过程可以划分为"通货膨胀区制"、"通货紧缩区制"和"通货变化适中区制",通货膨胀率过程在不同区制状态下均能够体现出显著的持续性特征.同时发现,我国经济政策操作与通货膨胀率所处区制之间以及经济政策调控与通货膨胀率所处区制的阶段性变迁之间都存在明显的相关性,这意味着在我国存在经济政策对价格水平变化所进行的及时动态干预和宏观调控.
利用馬爾科伕區製轉移模型來具體刻畫和分析我國通貨膨脹率過程的時間動態軌跡,檢驗結果錶明,我國通貨膨脹過程可以劃分為"通貨膨脹區製"、"通貨緊縮區製"和"通貨變化適中區製",通貨膨脹率過程在不同區製狀態下均能夠體現齣顯著的持續性特徵.同時髮現,我國經濟政策操作與通貨膨脹率所處區製之間以及經濟政策調控與通貨膨脹率所處區製的階段性變遷之間都存在明顯的相關性,這意味著在我國存在經濟政策對價格水平變化所進行的及時動態榦預和宏觀調控.

This paper uses Markov regime-switching model to investigate the dynamic path of China's inflation rate.According to the result of estimation and test,the inflation process in China can be divided into"high inflation regime"."low inflation regime"and"temperate inflation regime".The inflation rates in the different regimes ale able to reflect the obvious sustaining characteristics.At the same time,there is obvious correlation between China's economic policy mechanisms and the different regimes of inflation rates.This means that there exist the dynamic timely intervention and macro regulation and control of economic policy to the change of the price level in our country.
