Impact of Knowledge Management Performance on the Efficiency of R&D Active Firms: Evidence from Turkey

This study addresses to investigate the impact of the knowledge management (KM) performance on the efficiencies of 20 R&D active firms in manufacture of parts and accessories for motor vehicles industry in Turkey. The corresponding analysis is carried out using the traditional Data Envelopment Analysis (DEA) and DEA with weight restrictions. Shannon's Entropy Weighting is used to determine the weights of the input and output variables. Using the Mann-Whitney U test, the efficiency levels of firm which have low and high performance are compared. According to the results, there is significant difference between the efficiencies of the high-performance and low-performance R&D active firms in terms of the KM dimensions: knowledge creation, information system infrastructure, knowledge culture, and knowledge worker productivity.
