Abstract: In this work a class of locally SUSY GUTs with a nonminimal coupling is proposed. It is observed that from the superspace point of view the Wess-Zumino supergravity action is much simpler than the supergravity with the minimal coupling. So the overall scalar potential is derived and a new class of superpotential for the hidden sector is found. The effective potential thus derived turns out to be a generalization and improvement of the Ovrut-Wess mechanism. The above formalism is applied to a SU(5) SUSY GUT model and it is found that there is no anti de-Sitter problem any more, and the SU(2) x U(1) symmetry is broken at the scale M(,2/3). The squarks, sleptons, gluinos and photinos will get their masses radiatively. Besides, it is also discussed how to get a stable hierarchy.
