  1. Standard errors are in parentheses. The coefficients and standard errors are given according to model 4. All constructed models (models No. 1–4) are highly significant for all samples (p 0.0001)
  2. aR2 of production efficiency is calculated as the difference of R2 (model 2) and R2 (model 1) or it is equal ∆R2 (model 2)
  3. bR2 of internal financial factors is calculated as the difference of R2 (model 3) and R2 (model 2) or it is equal ∆R2 (model 3). R2 of external financial factors is calculated as the difference of R2 (model 4) and R2 (model 3) or it is equal ∆R2 (model 4)
