The quasar and galaxy cross-correlation functions are measured through the projected galaxy number density n(r_p) on scales $0.05<r_p<20 h^-1 Mpc around quasars for a sample of 2300 quasars from Schneider et al. (2007). We detect strong clustering signals at all redshifts, and find that the clustering amplitude increases significantly with redshift. We examine the dependence of the quasar-galaxy clustering on quasar and galaxy properties and find that the clustering amplitude is significantly larger for quasars with more massive black holes, or with bluer colors, while the dependence on quasar luminosity is absent. We also show that quasars have a stronger correlation amplitude with blue galaxies than with red galaxies. We finally discuss the implication of our finding.
