| Abstract: | We apply the stochastic frontier of translog production function to estimate the efficiencies of Chinese coal-fired power plants, using a survey sample of 300 power plants over 5 years from 2004 to 2008 for estimation. By taking into account, the ages of generators and a technological factor reflected by a dummy for supercritical generators, we identified the improvement of efficiencies in the Chinese power industry over the period, and the coal-fired power plants that still run inefficiently by approximate 9% on average when compared with the best practice of cost efficiency in the power industry. |
