Abstract: In this paper, some characterizations of nonemptiness and boundedness of solution sets for vector variational inequalities are studied in finite and infinite dimensional spaces, respectively. By using a new proof method which is different from the one used in Huang et al. (J Optim Theory Appl 162:548–558 2014 ), a sufficient and necessary condition for the nonemptiness and boundedness of solution sets is established. Basing on this result, some new characterizations of nonemptiness and boundedness of solution sets for vector variational inequalities are proved. Compared with the known results in Huang et al. ( 2014 ), the key assumption that $$K_\infty \cap (F(K))^{w\circ }_C=\{0\}$$ K ∞ ∩ ( F ( K ) ) C w ∘ = { 0 } is not required in finite dimensional spaces. Furthermore, the corresponding result of Huang et al. ( 2014 ) is extended to the case of infinite dimensional spaces. Some examples are also given to illustrated the main results.
