In this paper, we investigate the possibility to have supersymmetry breaking with background modulus fields in four-dimensional product-group gauge theories. The vacuum expectation values of the modulus fields satisfy several relations, and their dependences of the action can be fixed by loop-level consistency of the model. We examine the mass spectrum of vector and matter multiplets up to one-loop order of perturbation theory. As an application, it is found that the properties of higher-dimensional supersymmetry breaking are well captured in the various limits in the moduli space. In particular, we have finite radiative corrections to the Higgs masses in the case that is shown to be equivalent to the boundary condition breaking of supersymmetry.
