We consider Benson efficiency of a multi-product network equilibrium model based on Wardrop's principle in this paper. We show that in both the single and multiple criteria cases, such proper efficiency can be recast as vector variational inequalities. In the multiple criteria case we derive a sufficient and a necessary condition for Benson efficiency in terms of vector variational inequalities by using the Gerstewitz's function.
