We investigate theoretically the effects of the Coulomb interaction and spin-orbit interactions (SOIs) on the anisotropic transport property of semiconductor quantum wires embedded in (110) plane. The anisotropy of the dc conductivity can be enhanced significantly by the Coulomb interaction for infinite-long quantum wires. But it is smeared out in quantum wires with finite length, while the ac conductivity still shows anisotropic behavior, from which one can detect and distinguish the strengths of the Rashba SOI and Dresselhaus SOI.
