We study SUSY breaking and its transmission to the supersymmetric Standard Model in models with anomalous U(1) gauge symmetry where non-perturbative Polonyi term stabilizes the Green-Schwarz modulus. The pattern of SUSY breaking crucially relies on the ratio R between the Fayet-Iliopoulos term and the mass contribution of the Green-Schwarz modulus to the anomalous gauge boson. In the presence of anomalous U(1), soft SUSY-breaking terms are generated by modulus, anomaly and gauge mediations, whose relative importance is determined by the size of R. Furthermore, the anomalous D-term generically gives important contributions to soft scalar masses. The effects of anomalous U(1) on SUSY breaking can be understood more clearly within the low energy effective theory constructed by integrating out the anomalous vector superfield.
