Black hole accretion is widely thought to influence star formation ingalaxies, but the empirical evidence for a physical correlation between starformation rate (SFR) and the properties of active galactic nuclei (AGNs)remains highly controversial. We take advantage of a recently developed SFRestimator based on the [O II] $\lambda3727$ and [O III] $\lambda5007$ emissionlines to investigate the SFRs of the host galaxies of more than 5,800 type 1and 7,600 type 2 AGNs with $z < 0.35$. After matching in luminosity andredshift, we find that type 1 and type 2 AGNs have a similar distribution ofinternal reddening, which is significant and corresponds to $\sim10^9\,M_\odot$ of cold molecular gas. In spite of their comparable gas content,type 2 AGNs, independent of stellar mass, Eddington ratio, redshift ormolecular gas mass, exhibit intrinsically stronger star formation activity thantype 1 AGNs, in apparent disagreement with the conventional AGN unified model.We observe a tight, linear relation between AGN luminosity (accretion rate) andSFR, one that becomes more significant toward smaller physical scales,suggesting that the link between the AGN and star formation occurs in thecentral kpc-scale region. This, along with a correlation between SFR andEddington ratio in the regime of super-Eddington accretion, can be interpretedas evidence that star formation is impacted by positive feedback from the AGN.
