  We investigate a kind of interacting Chaplygin gas model in which the
Chaplygin gas plays the role of dark energy and interacts with cold dark matter
particles. We find that there exists a stable scaling solution at late times
with the Universe evolving into a phase of steady state. Furthermore, the
effective equation of state of Chaplygin gas may cross the so-called phantom
divide $w=-1$. The above results are derived from continuity equations, which
means that they are independent of any gravity theories. Assuming standard
general relativity and a spatially flat FRW metric, we also find the
deceleration parameter is well consistent with current observations.
