英文摘要：

In this paper, we discuss the stability of parametric primal and dual weak vector approximate equilibrium problems under the scalarization method. Firstly, the connectedness of approximate solutions set and the Hausdorff upper （lower） semi- continuity of approximate solution mappings to parametric primal weak equilibrium problems, under the assumption of nearly C-subcovexlikeness, are obtained. Then,under some weak assumptions, some su~cient conditions of the connectedness of approximate solutions set and the Hausdorff continuity of approximate solution map- pings to parametric dual weak vector equilibrium problems are obtained, by using the scalarization method. At last, an application in vector optimization problems is given. The obtained results improve and generalize the corresponding ones in the literature
