The dynamic density response and susceptibility of interacting electrons in 1D conductors is investigated taking into account the electron correlations reflecting the short-range order in a Luttinger liquid. We have shown that a narrow band of strong absorption appears in the dissipative susceptibility spectrum near to the wave vector 2kp due to the short-range correlations in addition to the commonly known delta-peak coming from the long-wave fluctuations. The adsorption band shape depends on the electron-electron interaction potential. This band is found to contribute dominantly to the dissipative conductance determined via the power absorbed in 1D conductor under local excitation.
