The correlation between inelasticity and cross section is discussed for a sample of theoretical models of multiparticle production which address the question of inelasticity and its energy dependence. In particular, assuming the gluonic origin of the growth of cross section, the two-component valon-gluon model (VGM) is formulated and the energy dependence of inelasticity is derived. It is pointed out that the resultant decrease in inelasticity arises as a consequence of the increase with energy of the abundance of gluonic collisions.
