Abstract The changing-look active galactic nucleus (CL-AGN), an extraordinary subpopulation of supermassive black holes, has attracted growing attention to understand its nature. We present an analysis of the spectral properties of 203 low-redshift CL-AGNs ( z log ( H β / O III ) = ( 0.63 ± 0.07 ) log ( L H α ) − (26.49 ± 2.96) ± 0.48 for Data Set B, as well as the correlation between H β /O iii and Eddington ratio ( L bol / L Edd ), log ( H β / O III ) = ( 0.59 ± 0.08 ) log ( L bol / L Edd ) + (1.02 ± 0.15) ± 0.53 for Data Set B, suggests that accretion rate variations drive changes in ionizing flux within the broad-line region, thereby triggering AGN type transitions. These findings underscore the critical role of supermassive black hole accretion processes in refining the AGN unification model. Future work should investigate potential connections between stellar evolution in outer accretion disk and the observed scatter in these correlations.
