The interplay of the excitonic, polaritonic and photonic condensation states due to the mass difference of electrons and holes in a microcavity is examined. In the framework of the unrestricted Hartree-Fock approximation adapting to the two electronic bands with the electron-hole Coulomb attraction and light-matter coupling, we find a set of self-consistent equations evaluating the order parameters of the condensation states. The excitonic and the photonic susceptibility functions are also specified in the random phase approximation. Our numerical results release the polaritonic condensate dominance at low excitation densities once enlarging the mass imbalance. The excitonic, polaritonic and photonic condensate competition in the influence of the Coulomb interaction and mass imbalance is also discussed
