粘滞价格模型以及对中国经济的数值模拟——对基本RBC模型的改进

Numerical Simulation for China Economy in a Sticky-price Model

本文在基本RBC模型的框架下,引入粘滞性价格和内生货币机制,建立包含货币政策的动态周期模型,并且用这个模型模拟了中国经济。我们的研究发现,在规则货币政策下,本文的模型给出的经济系统具有良好的稳定性,而且,模型能够模拟出比基本RBC模型更接近中国实际经济的周期特征。因此,本文给出的模型提供了一个能够较好地模拟中国实际经济政策运行的模型,通过它能够对现实经济政策有较好地解释。

This paper extends the basic RBC （Real Business Cycle） model to a framework with sticky-price and endogenous monetary policy to study the fluctuation of China＇s economy. It is found that the sticky- price model with regular monetary policy can simulate the fluctuations of real China＇s economy. Therefore, the model presented in this paper is a good selection for the study of China＇s economy. We can use this model to simulate the real economy in China.
