We discuss the possibility of the existence of a local correspondence between parton and hadron distributions in hard processes (a local parton-hadron duality). We make a first comparison with the data in order to test local duality at present-day energies. In particular, we show that beyond the double-logarithmic approximation of QCD perturbation theory the theoretical parton spectrum describes well the ..pi../sup + -/ spectrum in e/sup +/e/sup -/ annihilation for W> or approx. =20 GeV. We observe similar properties for the ..pi.., K, and p spectra. We propose further tests of local duality, as well as of chromodynamical coherence effects in jets.
