A class of generalized vector variational inequalities over product of sets and system of generalized vector variational inequalities are considered. The relationships of solution sets among those variational inequality problems are presented. With the hemi- continuity and several kinds of generalized monotonicities with respect to a vector, several existence results for the solutions of problems mentioned above are established by fixed point theorems of setvalued mappings.
