Electron condtrction in one-dinaaensional systetn is investigated explicitly taking into accountthe reservoirs to which 10 channel is connected at its ends. We calculate the ctrrrent driven bythe cheznical potential difference of two reservoirs, trsing the linear response theory by Kubo. AtOK, the conductance of 10 channel is expressed in terrns of one-electron Green's ftrnctions evenin the presence of the interaction, in contrast to the theory based on Ktrbo forrntrla, in whichtwo-electron Green's functions are essentially involved. The fornaalisna in this paper providesa new interpretation of' Landauer forratula. As regards the interaction ef['ects, the conductanceof Feruni liqtrid without potential scattering is 2e'/ h, while that of' Tornonaga-Luttinger liquiddeceases wuth power low as the length of' ID channel increases.
