We have analyzed a large sample of clean blazars detected by Fermi Large AreaTelescope (LAT). Using literature and calculation, we obtained intrinsic$\gamma$-ray luminosity excluding beaming effect, black hole mass, broad-lineluminosity (used as a proxy for disk luminosity), jet kinetic power from"cavity" power and bulk Lorentz factor for parsec-scale radio emission, andstudied the distributions of these parameters and relations between them. Ourmain results are as follows. (i) After excluding beaming effect and redshifteffect, intrinsic $\gamma$-ray luminosity with broad line luminosity, blackhole mass and Eddington ratio have significant correlations. Our resultsconfirm the physical distinction between BL Lacs and FSRQs. (ii) Thecorrelation between broad line luminosity and jet power is significant whichsupports that jet power has a close link with accretion. Jet power depends onboth the Eddington ratio and black hole mass. We also obtain $LogL_{\rmBLR}\sim(0.98\pm0.07)Log P_{\rm jet}$ for all blazars, which is consistent withthe theoretical predicted coefficient. These results support that jets arepowered by energy extraction from both accretion and black hole spin (i.e., notby accretion only). (iii) For almost all BL Lacs, $P_{\rm jet}>L_{\rm disk}$;for most of FSRQs, $P_{\rm jet}<L_{\rm disk}$. The "jet-dominance"(parameterized as $\frac{P_{\rm jet}}{L_{\rm disk}}$) is mainly controlled bythe bolometric luminosity. Finally, the radiative efficiency of $\gamma$-rayand properties of TeV blazars detected by Fermi LAT were discussed.
