Both gamma-ray bursts (GRBs) and pulsar wind nebula (PWNe) are energetic outflows that are produced in powerful high-energy astrophysical environments. Based on the correlations between the radio luminosity L_R and X-ray luminosity L_X as well as between the multiband spectral slope α_RX and radio flux F_R for compiled GRB and PWN samples, the radio and X-ray spectral properties are statistically investigated. The results show that (1) the correlations between L_R and L_X are consistent for GRBs and PWNe, within the uncertainties; and (2) for the whole sample, F_R is related to α_RX, and GRBs have lower α_RX than PWNe. It may be concluded that GRBs and PWNe have the same or similar particle acceleration mechanisms and radiation processes, i.e. synchrotron radiation, to produce the radio-to-X-ray band emission.
