Abstract:  A dependence structure model based on higher moment volatility, Copula-NAGARCHSK-M model, is proposed in this paper. The model is used to investigate the dependence structure of logarithmic returns, conditional variances, conditional skewnesses and conditional kurtosises between Shanghai and Shenzhen stock markets based on the consideration that the time-varying conditional variance risk, skewness risk and kurtosis impact on the marginal distributions. The evidences show that the dependence structures of returns, variances and kurtosises between both stock markets are similar, but the dependence structure between skewnesses is similar on the negative directional dependence.
