Abstract
The relevance of the study is due to significant differences in performance assessments based on non-parametric (DEA) and parametric (SFA) approaches. This problem leads to the inadequacy of the interpretation of the efficiency estimates and the incorrectness of the generated management decisions. The article calculates the DEA and SFA indicators of the efficiency for enterprises in six significant sectors of the Russian economy. A comparative analysis of the DEA and SFA estimates of efficiency in the context of industries and size of enterprises is carried out. We show the possibility of their joint use for making management decisions.
