We present a phenomenological analysis of higher Fack state contributions to the $\chi_{cJ}$ decays by using the recent BES experimental data. It is found that the higher Fock state $\mid (c\bar{c})_{8}g>$ makes an important contributions to the inclusive and exclusive processes with respect to that from the valence Fock state $\mid c\bar{c} >$ of the $\chi_{cJ}$ and some constraints of these contributions are obtained for the $\chi_{c0}$ and $\chi_{c2}$ states in order to fit the experimental data.
