ABSTRACT
This research aims at measuring and analyzing the technical efficiency of mining companies in the metal and mineral mining sub-sectors listed on the Indonesia Stock Exchange (IDX) in the 2012–2017 periods. The method used in this research on efficiency is a non-parametric Data Envelopment Analysis (DEA) method with an output-oriented BCC/VRS model. Based on the results of the research, it was found that the average efficiency score of metal and mineral mining companies was at a fairly efficient level with a score of 0.71. However, the individual efficiency scores showed that, from three selected companies, three companies still scored below 0.6 while the other three companies scored above 0.8. Furthermore, when compared based on the category of company ownership, it was found that the average efficiency level of state-owned companies was higher than private companies. However, when viewed individually, the efficiency score of one private company, i.e. INCO, was at an efficient level and with insignificant score difference with the state-owned companies TINS and ANTM.
