Abstract: The ARFIMA-FIAPARCH-skst model is applied to establish return-volatility model to CSI300 and HIS. Then the parameter estimated is combined to revise model to confine the final model and get rid of the effect of dependence relation from stylized facts in financial market. And then the mixed copula model made of Clayton, Frank and Gumbel is applied to establish a model of dependence structure. The result of the research indicates that evident of leverage effects found by the existing research hasn't been observed by local market and HongKong market. Moreover, the mixed copula model made of Clayton, Frank and Gumbel can describe the dependence structure between two markets accurately and the dependence relation of lower tail of two markets is stronger than the dependence relation of upper tail. Besides, the time varying mixed-copula also indicates that there is an obvious asymmetric dependence relationship.

Key words: financial market, stylized facts, mixed copula, dependence structure
