We study both polarized and unpolarized proton structure functions in the kinematical region of large Bjorken x and four-momentum tranfer of few GeV2, characterized by the phenomenon of parton-hadron duality between the smooth continuation of the deep inelastic scattering curve and the average of the nucleon resonances which dominate this region. We present results on a perturbative-QCD analysis using recent accurate data aimed at extracting the infrared behavior of the nucleon structure functions.
