The main purpose of this paper is to compare the efficiency of sector manufacturing base metal in 25 European countries. 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. This article presents the use the input-oriented CCR and BCC model, to determine overall technical efficiency, pure technical efficiency and scale efficiency of sector manufacturing base metal in European countries. The analysis gives a possibility to create a ranking of counties. The results point out the reasons of the inefficiency and provide improving directions for the inefficient Decision Making Units..
