Abstract： To model the observed Universe containing both dark energy and dark matter, we study the effective Yang- Mills condensate model of dark energy and add a non-relativistic matter component as the dark matter, which is generated out of the decaying dark energy at a constant rate Γ, a parameter of our model. For the Universe driven by these two components, the dynamic evolution still has asymptotic behaviour: the expansion of the Universe is accelerating with an asymptotically constant rate H, and the densities of both components approach to finite constant values. Moreover, ΩΛ 0.7 for dark energy and Ωm 0.3 for dark matter are achieved if the decay rate Γ is chosen such that Γ/H ~ 1.
