ECONOMIC AND ENVIRONMENTAL EFFICIENCY OF THE METAL INDUSTRY IN EUROPEAN COUNTRIES

The article specifies the economic and environmental efficiency in the metal industry in individual EU countries in 2015. The study applies Data Envelopment Analysis (DEA), which is a non-parametric method based on production theory and the principles of linear programming. It enables one to assess how efficiently a firm, organization, country, or such other decision making unit (DMU) uses the available inputs to generate a set of outputs relative to other units in the data set. The analysis gives a possibility to create a ranking of countries. The results point out the reasons of the inefficiency and provide improving directions for the inefficient Decision Making Units.
