Sfermion masses and eigenstates in the supersymmetric economical 3-3-1 model are studied. By lepton number conservation, the exotic squarks and superpartners of ordinary quarks are decoupled. Due to the fact that in the 3-3-1 models, one generation of quarks behaves differently from other two, by R-parity conservation, the mass mixing matrix of the squarks in this model are smaller than that in the Minimal Supersymmetric Standard Model (MSSM). Assuming substantial mixing in pairs of highest flavours, we are able to get mass spectrum and eigenstates of all the sfermions. In the effective approximation, the slepton mass splittings in the first two generations, are consistent with those in the MSSM, namely: m²_{_L}−m²_{_lL} = m_W²cos 2γ; (l = e, μ). In addition, within the above effective limit, there exists degeneracy among sneutrinos in each multiplet: m²_{_lL} = m²_{_lR}. In contradiction to the MSSM, the squark mass splittings are different for each generation and not to be m_W²cos 2γ.
