Abstract
The main purpose of the study is the efficiency and productivity analysis of selected firms that operating in the Turkey food processing industry in 2015-2019 period. In the study, two variables, namely the equity of the firms and the number of paid employees, are used as input, while the net sales values of the firms are used as output. Estimates were made in two stages using the Data Envelopment Analysis method and the Malmquist index approach as a method. The technical efficiency results of the firms in the first stage showed that all firms except one firm operate below the optimal scale. The results of the Malmquist index in the second stage of the study showed that the technical efficiency changes of all firms increased in the examined period, and there was an increase in productivity in all firms except for three firms. However, technological development changes in most of the companies decreased in the period under consideration. According to the results, the decrease in technological change was determined as the important factor causing the decrease in productivity of these companies.
