Abstract: This study evaluates the relative efficiencies of Japan Railway companies (hereinafter “JRs”) and Japan's major private railway companies (hereinafter “Private Railways”), using various types of DEA (Data Envelopment Analysis). As the eighth report, this paper verifies the effects on the privatization and separation of JNR (Japan National Railways) to the relative efficiency and inefficiency of JRs and Private Railways by using the parametric and nonparametric test of DEA and Inverted DEA (Inverted Data Envelopment Analysis). More specifically, in this paper, the first step of the evaluation of the relative efficiencies and inefficiencies to the productivity and others of each JR and Private Railways for a total of 19 years after the privatization and separation of JNR by using DEA and Inverted DEA. The second step of the verification of the effects on the privatization and separation of JNR to the productivity and others of each JR and Private Railways by using the parametric and nonparametric test of DEA and Inverted DEA are clarified. The verification of the effects on the privatization and separation of JNR of the productivity and others of each JR was identified statistically.
