  We analyze the static QCD potential V_QCD(r) in the distance region 0.1 fm <
r < 1 fm using perturbative QCD and OPE as basic theoretical tools. We assemble
theoretical developments up to date and perform a solid and accurate analysis.
The analysis consists of 3 major steps: (I) We study large-order behavior of
the perturbative series of V_QCD(r) analytically. (II) In the frame of OPE, we
define two types of renormalization schemes for the leading Wilson coefficient.
(III) We compare numerically perturbative predictions of the Wilson coefficient
and lattice computations of V_QCD(r). We perform fits to simultaneously
determine non-perturbative contribution and the relation between lattice scale
and Lambda_MSbar. (Short version)
