Modeling the Efficiency of Real Sector Enterprises
Konstantin Lvovich Polyakov
In this study we assess the impact of external factors on the technical efficiency of real sector enterprises. The sample included companies from three sectors of extractive industry. A two-stage model is used for assessment. The technical efficiency of enterprises is calculated at the first stage by using standard output-oriented DEA model and variable returns to scale. A linear regression model using panel data is assessed at the second stage. The most suitable model is random effects regression which is used for assessing the impact of external factors on the technical efficiency of enterprises.
