  It is demonstrated, that 't Hooft's renormalization scheme (in which
\beta-function has exactly the two-loop form) is generally in conflict with the
natural physical requirements and specifies the type of the field theory in an
arbitrary manner. It violates analytic properties in the coupling constant
plane and provokes misleading conclusion on accumulation of singularities near
the origin. It artificially creates renormalon singularities, even if they are
absent in the physical scheme. The 't Hooft scheme can be used in the framework
of perturbation theory but no global conclusions should be drawn from it.
