By choosing two typical input parameter points in the minimal supergravity (mSUGRA) model and using the QCD factorization (QCDF) approach, we studied the supersymmetric (SUSY) effects to the CP violation of the two-body charmless hadronic B meson decays. We found that though the SUSY contributions can give large corrections to the CP asymmetries for some decay channels, they could not be distinguished experimentally from the standard model (SM) values because of the large theoretical errors dominated by the annihilation contributions in the QCDF approach.
