Abstract

Tis study attempts to obtain Technical Eficiency (TE),Allocative Eficiency (AE) and Average Eficiency ofdynamic DEA-Window analysis scores of 31 railwayfirms operating worldwide. Te data set covering theperiod of 2000 to 2009 is analyzed by CCR and BCCmethods. In the analysis conducted by use of the CCRmodel, while total 17 firms are eficient in the first year,this figure reaches to 18 firms for the last year with oneincrement. With input oriented and variable returnanalysis conducted by use of the BCC model, the firmshaving TE at the beginning of the period were 20 innumber. At the end of the period, the figure reaches to24. Window analysis suggests that all firms in generalhave stable average eficiency rate and ineficiencies ofthe firms and standard deviations of their eficiencyscores exhibit a similar pattern. Malmquist Index (MI)analysis also suggests that Total Factor Productivityhas increased by 0.03% for the entire period.

Özet

Bu çalışmada, 2000-2009 döneminde faaliyette bulunan 31 adet dünya demiryolu şirketinin VZA- PencereAnalizi ile dinamik Teknik Etkinlik ve Tahsis Etkinliğive Ortalama Etkinlik skorları CCR ve BCC metotlarıyla elde edilmek istenmiştir. CCR modeli ile yapılananalizde ilk yıl için toplam 17 firma etkin iken 2009yılı için bu sayı 18 firmaya çıkmıştır. BCC modeli ilegirdi yönelimli ve değişken getirili analizde dönem başında teknik etkinliğe sahip firma sayısı 20 iken dönemsonunda bu rakam 24e çıkmaktadır. Pencere Analizibulguları tüm firmaların dengeli bir ortalama verim lilik oranı ve benzer yapıda standart sapma değerlerine sahip olduklarını göstermektedir. Toplam FaktörVerimliliği için Malmquist Endeksi kullanılarak yıllarboyunca tüm işletmeler için Toplam Faktör Verimliliğinin sadece binde üç düzeyinde arttığı tespit edilmiştir.
