内容記述
This study evaluates the relative efficiencies of Japan Railway companies and Japan's major private railway companies, using various types of DEA (Data Envelopment Analysis). As the seventh step of the evaluation, this paper illustrates trends of the results of the relative efficiencies and inefficiencies of each Japan Railway company using the DEA/Window Analysis and the Inverted DEA/Window Analysis by a total of 19 years after privatization and separation of the Japan National Railways. In this paper, trends of the relative efficiencies and inefficiencies of each Japan Railway company became clear by various illustrations. In the past papers of the author, the first step of the evaluation focused on the time series performance data analysis of the Japan Railway companies. The second step of the evaluation focused on the relative efficiencies of Japan Railway companies using the DEA/Window Analysis. The third step of the evaluation focused on the relative inefficiencies of Japan Railway companies using the Inverted DEA/Window Analysis. The fourth and fifth steps of the evaluation focused on the relative efficiencies and inefficiencies of Japan's major private railway companies (in eastern and western Japan) using the DEA/Window Analysis and the Inverted DEA/Window Analysis. The sixth step of the evaluation was illustrated by using the Candlestick for trends of those results of the relative efficiencies and inefficiencies of each railway company.
