摘　　要：In this paper, we shall be concerned with what happens of Gorenstein homological dimensions when certain modifications are made to a ring. The five structural operations addressed later are the formation of excellent extensions, localizations, Morita equivalences, polynomial extensions and power series extensions.In this paper, we shall be concerned with what happens of Gorenstein homological dimensions when certain modifications are made to a ring.
