In this paper, we study vector equilibrium problems with the ordering relations defined via improvementsets in real linear spaces without assuming any topology. We deal with efficient solutions, weak efficient solutions, Benson and Henig proper efficient solutions. The linear scalarization characterizations of these solutions are established, moreover, optimization conditions via Lagrange multiplier rulers for vector equilibrium problems with constraints are also obtained. Our results generalized the corresponding ones in the literature.
