Consistent relativistic approach is proposed to the investigation of asymptotic behaviour
of form-factor of a system composed of two spinor particles, interacting with
the vector or (pseudo) scalar neutral field. It is shown that the assumption of finite
and small asymptotical value of the quark-gluon interaction invariant charge $(g_0^2\ll 1)$
leads to the “quark counting rules” in the parton region $(g_0^2\, \ln\, (-q^2)\ll 1)$ and to thereaking of these rules at greater $-q^2$ values.
