The self-consistent mean field in the many-body correlation dynamics is discussed in detail. It is shown that the self-consistent mean field exists in general in many-body correlation dynamics for both stationary and non-stationary cases. The many-body correlations enter the mean field through the two-body correlation c2 and the corresponding collision term I. The role played by I is twofold i.e., dynamical effects and statistical effects on single particle states. The many-body correlations also manifest their effects on the many-body energy and yield an energy expression different from the conventional expression in the HF-Bruc-kner theory.
