　　　 （ABSTRACT）

The supersymmetric extension of the economical 3-3-1 model is presented. We explore the Higgs sector in this model and find some new features. There are three Higgs bosons having masses equal to that of gauge bosons -the W and extra bilepton gauge bosons X and Y . There is one scalar boson with mass of 91.4 GeV, which is closed to the Z boson mass and in good agreement with the present limit: 89.8 GeV at 95% CL. The Higgs phenomenology in the framework of the supersymmetric economical 3-3-1 model is studied and production of the charged Higgs boson via WZ fusion at LHC. Some cosmological implications in the supersymmetric economical 3-3-1 model are presented such as Dark matter and hybrid inflationary scenario. The strong limit from the allowed CMB data can be translated to constrain parameters in the model.
