We study properties of the Polonyi field in the renormalizable hidden sector in supergravity models. It is shown that radiative corrections induce a sizable coupling of the Polonyi field to gravitinos as well as raise its mass to an intermediate scale. We find it serves a solution of the Polonyi problem and show that the gravitino abundance produced by the Polonyi decay is not large. It is also pointed out that soft supersymmetry breaking terms induced by this hidden sector are very restricted.
