The rise of the factor R=σ(e^+e^-⇾hadrons)/(4πα^2/3s) for energies available in recent experiments is explained within the framework of the parton field theory. Assuming that the electromagnetic current couples minimally to the parton fields, we find that contributions toσ(e^+e^-⇾hadrons), due to the parton-antiparton interactions, dominate over the so-called light-cone contribution, at least in the energy region available at present. We show within the pole approximation for partons that the factor R is bounded by 5 times ordinary quarkparton predictions for R. Experimental data on R is well reproduced by a suitable choice of the parton-antiparton interaction term. A comment is directed toward a possible connection of the absence of isolated free partons to the "serotinous" scaling in the process e^+e^-⇾hadrons.
