摘要：
In this paper we apply the statefinder parameters to the interacting phantom energy with dark matter. There are two kinds of scaling solution in this model. It is found that the evolving trajectories of these two scaling solutions in the statefinder parameter plane are quite different, and that they are also different from the statefinder diagnostic of other dark energy models.
