  The dependence of the spectra shape of produced charged hadrons on the size
of a colliding system is discussed using a two component model. As a result,
the hierarchy by the system-size in the spectra shape is observed. Next, the
hydrodynamic extension of the two component model for hadroproduction using
recent theoretical calculations is suggested to describe the spectra of charged
particles produced in heavy-ion collisions in the full range of transverse
momenta, $p_T$. Data from heavy-ion collisions measured at RHIC and LHC are
analyzed using the introduced approach and are combined in terms of energy
density. The observed regularities might be explained by the formation of QGP
during the collision.
