We study properties of the Polonyi field in the renormalizable hidden sector in supergravity models. It is shown that radiative corrections induce a sizeable coupling of the Polonyi field to gravitinos as well as raise its mass to an intermediate scale. We find that it provides 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.
