Statistical analysis of the correlation between the mean rate of optical variation and the redshift are made for 34 QSOs and nine active galaxies with light curve and redshift value. It is shown that the mean rate of optical variation of QSOs is decreased with the increasing redshift, while the mean rate of optical variation of active galaxies is higher than those of QSOs. From the viewpoint of cosmological evolution it seems that the optical variation of QSOs becomes more violent with the cosmological time, and finally connects itself with that of active galaxies.
