Relations between Gorenstein derived categories, Gorenstein defect categories and Gorenstein stable categories are established. Using these, the Gorensteinness of an algebra $A$ and invariants with respect to recollements of the bounded Gorenstein derived category $D^{b}_{gp}(A\mbox{-}{\rm mod})$ of $A$ are investigated. Specifically, the Gorensteinness of $A$ is characterized in three ways: the existence of Auslander-Reiten triangles in $D^{b}_{gp}(A\mbox{-}{\rm mod})$; recollements of $D^{b}_{gp}(A\mbox{-}{\rm mod})$; and also Gorenstein derived equivalences. It is shown that the finiteness of Cohen-Macaulay type and of finitistic dimension are invariant with respect to the recollements of $D^{b}_{gp}(A\mbox{-}{\rm mod})$.
