摘要 文章用PARCH模型对人民币对美元汇率波动性进行了研究,在不同的尾项分布下进行了对比分析.结果显示,外部冲击对美元兑人民币中间价有持久性的影响,即汇率市场如果出现较大的波动,在短时间内是无法消除的,并且在学生T分布下更能体现尾项的真实分布. The PARCH model is applied in this paper for an empirical study of RMB against US dollar exchange rate volatility,and to make a comparison under different tail of distribution. The results indicate that the RMB's exchange has a significant leverage effect on the dollar's exchange rate volatility,and it can reflect real distribution of the tail item under student T distribution.
