Abstract：
We study the properties of nuclear matter and finite nuclei in terms of the quark-meson coupling model with a density-dependent bag constant, which is extracted from the SU(3) Nambu-Jona-Lasinio(NJL) model. It is shown that this model provides a reasonable description for nuclear matter and finite nuclei. The rearrangement potential due to density-dependent bag constant plays an important role in this model.
