The alternative approach to QCD analysis of the photon structure function$F_2^{\gamma}$ is presented. It differs from the conventional one by thepresence of the terms which in conventional approach appear in higher orders.We show that this difference concerns also the photonic parton distributionfunctions. In the alternative approach, the complete LO analysis of$F_2^{\gamma}$ can be performed as all required quantities are known. At theNLO, however, one of the coefficient function is so far not available and thusonly the photonic parton distribution function can be computed and compared tothose of standard approach. We discuss the numerical difference of theseapproaches at the LO and the NLO approximation and show that in case of$F_2^{\gamma}$ this difference is non-negligible and may play an important rolein the analysis on photon data of the future experiments.
