I will present the clustering measurement results in the COSMOS2015 catalogue. We measured the stellar mass function and the two-point correlation function between redshifts 0.2 and 6, and interpreted it using a HOD model. I will show the stellar-to-halo mass ratio for both the central and satellite galaxies. This measure is an indicator of past star-formation efficiency and can be linked to the processes that enhance or slow down star formation. In particular, the clustering measurements allow to give an accurate picture of the satellites in massive halos, and is a sensitive probe of feedback processes that affect (or not) the large-scale environment.
