Abstract :This study attempts to obtain Technical Efficiency (TE), Allocative Efficiency (AE) and Average Efficiency of dynamic DEA-Window analysis scores of 31 railway firms operating worldwide. The data set covering the period of 2000 to 2009 is analyzed by CCR and BCC methods. In the analysis conducted by use of the CCR model, while total 17 firms are efficient in the first year, this figure reaches to 18 firms for the last year with one increment. With input oriented and variable return analysis conducted by use of the BCC model, the firms having TE at the beginning of the period were 20 in number. At the end of the period, the figure reaches to 24. Window analysis suggests that all firms in general have stable average efficiency rate and inefficiencies of the firms and standard deviations of their efficiency scores exhibit a similar pattern. Malmquist Index (MI) analysis also suggests that Total Factor Productivity has increased by 0.03% for the entire period.Keywords : Panel Data, DEA, TFP, Railway
