We present a clustering analysis for Lyman-break galaxies (LBGs) at z ˜ 3 -- 5 and K-band selected BzK galaxies at z ˜ 2 using wide-field multi-color data on two blank fields: the Subaru Deep Field and the Subaru/XMM-Newton Deep Field. We then combine our clustering measurements with those taken from the literature, to discuss the dependence of the star-formation rate and stellar mass of galaxies on the mass of hosting dark haloes for high-z galaxies. We find that the star-formation rate of LBGs linearly correlates with the mass of hosting dark haloes, and that within rather large uncertainties, dusty star-burst galaxies (distant red galaxies, ultra-luminous infrared galaxies, and submillimeter galaxies) appear to be simple scaled-up populations of LBGs in terms of their star-formation efficiency. We also find a positive correlation between the stellar mass and the dark-halo mass for K-selected galaxies. A detailed analysis for z ˜ 3 LBGs reveals that there are upper limits on the star-formation rate and the stellar mass which are determined by the mass of hosting dark haloes.
