Zero-bias resistances of a single resistance-shunted Josephson junction are calculated as function the temperature by means path-integral Monte Carlo method in case charging energy $E_{\rm C}$ is comparable with J}$. The low-temperature behavior zero-bias resistance changes around $\alpha=R_{\rm Q}/R_{\rm S}=1$, where $R_{\rm S}$ shunt and Q}=h/(2e)^2$. dependence shows power-law-like whose exponent depends on J}/E_{\rm C}$. These results compared experiments junctions.
