摘要：
Statefinder diagnostic is a useful method which can distinguish one dark energy model from the others. In this paper, we apply this method to the GCG model with and without viscosity. It is shown that the evolving trajectory of the viscous GCG model in the s-r diagram is not only quite different from the model without viscosity but also different from other dark energy models.
