Abstract: This paper establishes Gumbel Copula model based on AR(1)-GARCH(1,1),and then portrays the correlation between the real estate of return and volumes through Gumbel Copula model.By AIC information criterion for testing goodness it is found that the Gumbel Copula is  better to describe the dependence structure between the price return and volumes.Results show that there is an asymmetrical dependence of higher upper tail between them,but  the positive dependence is not strong.

Key words: Copula, returns, trade volume, correlation
