| 摘 要： | 为了刻画宏观经济与股票市场波动间的相关性,在静态Copula模型的基础上,应用了一种全新的条件动态Copula(DCC-Copula)技术,它可以捕捉到经济变量间动态的相关结构。结合Gaussian-GARCH模型和DCC-Copula函数,建立了DCC Copula-GARCH模型全面对宏观经济变量与股票市场之间相关性进行了分析。结果说明,随着时间的变化,宏观经济与股票市场波动之间存在着较稳定的正相关关系。

| Abstract: | In order to depict the correlation between macro economy and volatility of stock .market. This paper applies a new kind of dynamic conditional correlation-Copula technology based on the model of static Copula. And this DCC-Copula model can capture the dynamic correlation structure between the economic variables. Combining Gaussian-GARCH model with DCC-Copula function, the paper builds DCC Copula-GARCH model and makes a full correlation analysis of macro-economic variables and stock market. The result shows that there has been a relatively stable positive correlation ship as the time gone. |
