 note = {This paper examines the efficiency of electric utilities. Electric utilities are monopolized under regulation. As I think there are any X-inefficiencies in this industry, I tried to measure productive efficiency originally presented by Farrell and expanded as Data Envelopment Analysis by Charnes-Cooper-Rhodes.
　Results show that overall efficient, that is, "D efficient" utilities are Tokyo Electric Power Company(TEPCO) and Southern California Edison Company(SCE) .
　This is my first analysis to the Yardstick Competition of electric utilities by DEA method and I expect that it may make some contribution to decisions of Regulatory Agency and electric utilities of Japan.},
