The relation between the γ-ray and the emission line luminosities for a sample of 36 γ-ray loud blazars is investigated; an apparent correlation between them, Lγ ∝ LLine0.69±0.11, with a correlation coefficient r=0.741 and a chance probability of p = 1.9×10-6, is found. It is found, however, that there is no intrinsic correlation between them: the apparent correlation is due to the redshift dependence in a flux-limited sample. Thus no evidence is found to support the argument that the up-scattered soft photons are from the broad emission lines. Our analysis does not conflict with the SSC model. The disk-jet symbiosis and radio/γ-ray correlation found in the literature are also discussed. The radio/γ-ray correlation may be an apparent correlation caused by the boosting effect since both bands are strongly beamed.
