The aim of this study was to evaluate productivity and efficiency of intellectual capital of companies listed in Tehran Stock Exchange through Data Envelopment Analysis approach and Malm-quist productivity index. In this study, the automotive industry and component manufacturers listed in Tehran Stock Exchange were chosen as pilot, and intellectual capital (human, physical, and structural capital) index was used as input index; stock return, return on assets, and return on equity were utilized as output variables for fifteen companies of this industry between 2006 and 2010. Results from the efficiency of intellectual capital indicated that throughout the years of assessment in this study, it was only a -brake- pad company that had the best performance among the selected companies; this was due to the fact that this company had been able to gain the maximum performance of intellectual capital in the assessed years. Results from the productivity of intellectual capital indicated that in the years between 2006 and 2010, except Saipa, Bahman Group, Zamyad which had a value smaller than 1 for the average productivity rate of their intellectual capital in the investigated growth range, this value was positive for the rest of the selected companies.
