The formation and growth of supermassive black holes (SMBHs) physically linked with bulges are considered. We focus on the radiation hydrodynamic process for the growth of SMBH in the optically thick starburst phase, where radiation from bulge stars drives the mass accretion on to a galactic center through radiation drag effect. In the present scenario, the AGN luminosity-dominant phase (QSO phase) is preceded by the host luminosity-dominant phase, which is called “proto-QSO phase”. Comparing with observations, we found that the ultraluminous infrared galaxies that contain a type I Seyfert nucleus (a type I ULIRG) are the early phase of BH growth, namely correspond to the proto-QSO phase.
