To infer whether the jet production efficiency depends on the host properties or is determined just by intrinsic properties of the accretion flows we compared optical properties of the host galaxies of radio-quiet (RQ) and radio-loud (RL) Type 2 AGNs. We carefully selected galaxies from SDSS, FIRST, and NVSS catalogues. We confirmed that the fraction of RL AGNs increases with the black hole (BH) masses and decreases with the Eddington ratio. Therefore, the comparison of the nature of the hosts of RL and RQ AGNs requires pairmatching techniques. By pairing RL and RQ samples in BH mass, Eddington ratio and redshift, we showed that the radio-loudness correlates with the host-galaxy concentration index and morphological type, and anti-correlates with the recent specific star-formation rate and dust attenuation. Contrary to some previous studies, we found no significant difference between our radio-loud and radio-quiet samples regarding merger/interaction features.
