 note = {I have investigated an efficiency of electric power utilities of the United States and Japanese electric companies using data envelopment analysis. The analysis can be newly constructed with an effective graphical expression of the efficiency in a diagram of two-iuput one-output models. I　show that it is very useful to graphically illustrate the assessment of efficiencies due to the analysis based on time series data with several examples and discussion.},
