Deep- and wide-field images of the CFHTLS Deep Survey enable us to obtain sufficiently accurate two-point angular correlation functions to apply a halo occupation distribution analysis. The mean halo masses, calculated as $M_h = 10^11.7 - 10^12.8 h^-1 M_ødot$, increase with stellar-mass limit of LBGs. The threshold halo mass to have a central galaxy, $M_min$, follows the same increasing trend with the low-$z$ results, whereas the threshold halo mass to have a satellite galaxy, $M_1$, shows higher values at $z = 3 - 5$ than $z = 0.5 - 1.5$ over the entire stellar mass range. Along with considering the low satellite fractions in high-$z$, these results suggest that satellite galaxies form inefficiently within dark haloes at $z=3-5$ even for less massive satellites with $M_\star < 10^10 M_ødot$. We compute stellar-to-halo mass ratios (SHMRs) assuming a main sequence of galaxies, which is found to provide consistent SHMRs with those derived from a spectral energy distribution fitting method. The observed SHMRs are in good agreement with the model predictions based on the abundance-matching method within $1\sigma$ confidence intervals. We show, for the first time observationally, the increasing trend of $M_h^pivot$, which is the halo mass with a peak SHMR, with cosmic time at $z > 3$, and with keeping the constant star-formation efficiency indicates that mass growth rates of stellar components and dark haloes are comparable at $3 < z < 5$.
