摘  要: We build an empirical method to link galaxy stellar mass directly with its hosting dark matter halo mass at redshift z=0, and apply the model to a higher redshift of around 0.8. The $M_{stars}$-$M_{infall}$ relations of the galaxy stellar mass $M_{stars}$ and the host halo mass M_{infall} at two redshifts are constrained by fitting both the stellar mass function and the correlation functions at different stellar mass intervals of the SDSS and VVDS observation.  We can also predict stellar mass functions of redshifts up to z~ 3, and the results are consistent with the latest observations.
