| 摘 要： | 文章将沪市(深市)A股、沪市(深市)B股和H股纳入一个研究框架,采用1995-2008年样本数据,运用GJR-GARCH-ADCC模型对三个市场的收益率条件相关性进行了实证分析.结果表明,A股和B股,B股和H股相关性受非对称信息影响,而A股与H股间不受非对称影响.本文还检测了三个主要的市场开放政策对市场间相关关系影响,发现B股市场开放后,A、B市场相关关系有明显的结构变动,联动性增强;QDII政策的实施加深了深市A股和H股,深市B股和H股的联系;但QFII政策对各市相关性影响不明显.整体说明国内证券市场,特别是A股和B股,A股和H股,融合度加深,联动性增强.

| Abstract: | This paper investigates the dynamic conditional correlation among the A-share, the B-share and the H-share markets in China. By applying the GJR-GARCH-DCC with asymmetric term model , we analyze three return indices during the period of 1995-2008. We find that the correlation between the A-share and the B-share markets, as well as the one between the B-share and the H-share markets are dynamic and asymmetric. However, the correlation between the A-share and the H-share markets is dynamic but not asymmetric. The results are important to portfolio diversification and for financial market participants. We also find that the A- and B-share markets as well as the A- and H-share markets are increasingly integrated. |
