In the current $α_s$ determinations based on lattice and perturbation theory, it is generally difficult to take a wide enough matching range. We avoid this problem by improvement of a theoretical calculation: we use the OPE with renormalon subtraction, which is an extended framework of perturbation theory. This allows us to take the matching range widely as $Λ_QCD^r$$\utilde{<}
.0.6$, where relatively low energy scales are included. We obtain $α_s$ ($m_Z$) = 0.1179+0.0015−0.0014 from a reasonable fit for this wide range.
