  As an elaboration of the analytic approach to Quantum Chromodynamics (QCD), a
new model for the QCD analytic running coupling is proposed. A self-evident
advantage of the new analytic running coupling (NARC) is that it incorporates
the infrared enhancement and the ultraviolet asymptotic freedom in a single
expression. It is essential that additional parameters are not introduced in
the theory. The absence of unphysical singularities in the physical region
$q^2>0$ and a fairly well loop and scheme stability are the remarkable features
of the NARC. By making use of practically the same values of $\Lambda_{QCD}$ in
the approach developed, one succeeded in description of various physical
phenomena, from quark confinement to the $\tau$ lepton decay. This undoubtedly
implies that the new analytic running coupling substantially involves both the
nonperturbative and the perturbative behavior of Quantum Chromodynamics.
