摘要：

The cosmological model of the modified Chaplygin gas (MCG) interacting with cold dark matter is studied. Our attention is focused on the final state of the universe in the model. It turns out that there exists a stable scaling solution, which provides the possibility of alleviating the coincidence problem. In addition, we investigate the effect of the coupling constants c(1) and c(2) on the dynamical evolution of this model from the statefinder viewpoint. It is found that the coupling constants play a significant role during the dynamical evolution of the interacting MCG model. Furthermore, we can distinguish this interacting model from other dark energy models in the s-r plane.
