In identifying the relative efficiencies of the firms, Data Enveloping Analysis were utilized, and in introducing the variation of total factor productivity in time Malmquist Total Factor Productivity Index. According to the results of analysis , under the assumption of constant return, in the years of 2011 and 2013, it was identified that only Oyak Renault reached maximum output and in the years of 2012, 2014, and 2015, Hyundai Assan and Oyak Renault. Under the assumption of variable return, it was identified that in the years of 2011, 2012, 2014 and, 2015, A.I.O.S., Hattat Tarım, Hyundai Assan, Otokar, Oyak Renault and Türk Traktör took place on the frontier of full production and in 2013, A.I.O.S., Hattat Tarım, Otokar, Oyak Renault and Türk Traktör. When scale efficiencies are examined, it was identified that in the years of 2011 and 2013, Oyak Renault made production in optimal production scale and in the years of 2012, 2014, and 2015, Hyundai Assan and Oyak Renault, while the scale efficiencies of the other firms were less than from the other aspect, it was identified that total factor productivity of Turkish automotive industry increased by 14% and that maximum increase on the basis of firm actualized in the firm A.I.O.S. }, number={2}, publisher={Çankırı Karatekin Üniversitesi}
