We studied the consequences of the consistency condition imposed by the truncated perturbation theory on the renormalization-scheme (RS) dependence of perturbative QCD calculations. By studying several physical quantities being free from or insensitive to the factorization-scheme dependence, we found the followings : (1) The significance of the RS-dependence is almost independent of the process considered, (2) higher order contributions are always important and nonnegligible from the point of the oretical consistency, and (3) the resolution of the RS-dependence is really important in order to make quantitative confrontations of perturbative QCD with experiment.
