摘　　要：本文以沪深指数、恒生指数、标准普尔指数和DAX指数为对象,以金融危机和欧债危机为分界点,分析四个股市在危机前后的联动性及其差异。研究表明:金融危机前,标准普尔指数对沪深指数的冲击不明显,危机后,冲击影响程度加深;次贷危机前,沪深指数受DAX指数的冲击不明显,危机后,冲击影响程度加深。同时,沪深指数的冲击没有对标准普尔指数和DAX指数带来显著的影响,但在国际金融危机发生后,其影响变得稍大一些。金融危机发生前,沪深指数与其他股票指数的动态相关系数明显小于金融危机后的系数,而且金融危机后股票指数波动率的联动性加强。美国股票市场引领其他市场的涨跌,是四个股票市场波动的发源地。The paper analvses whether there is contagion among Shanghai ＆ Shenzhen stock market index, DAX index Heng Seng index and Standard ＆ Poor＇s index with the financial crisis and european debl crisis as the cut -off point.
