我们在向量自回归模型中引入了增长率水平和产出波动性的双区制状态变量和状态之间的马尔可夫转移过程,并对我国经济增长率与波动性之间的影响关系进行了描述和检验。通过检验发现,我国经济增长速度与波动程度之间存在显著的相关性,不同区制状态中经济增长速度与条件波动性的相关性程度有所不同,体现出经济波动“溢出效应”的非对称性。我国经济中适度增速和适度波动性的区制状态组合具有最强的稳定性和持续性,这说明我国经济已经进入持续快速稳定的增长阶段。
By using the vector error correct model with Markov regime switching of two state variables, we describe and test the correlations of output volatility with growth. We find the evidence that there is a significant relationship between volatility and growth, and the patterns of correlation vary asymmetrically with the regimes. We also find that the regime with middle growth and volatility lasts longer and keeps stable. This means that China~ economy has gone into the stable and rapid growth stage.
