Abstract
The perturbative part of the effective QCD Lagrangian was constructed by the renormalization group approach in the 4-loop approximation. It was extrapolated in the non-perturbative region under the assumption of the existence of gluon condensate at (F_{\mu\nu}^j)^2=F_0^2. The best result is F_0^2\approx 0.4 GeV^4.
