| The coal-fired electric industry in china is confronting a puzzle which is more inputs, lower efficiency and more emissions than others'. The necessary mothods of sloving the conflict between the shortage of electric power and the environmental pollution are to improve environmental technical efficiency and reduce pollution in the coal-fired electric industry. Firstly, the study adopts directional distance functions to measure the environmental technical efficiency of Chinese coal-fired electric industry over the period 2001 to 2007, and compares the difference between environmental technical efficiency and technical efficiency, analyses simultaneously the relation between the manner of grown and changes in technical efficiency. Secondly, analyses the influence of capacity utilization rate, fuel efficiency and environmental regulation on the environmental technical efficience through panel data and general least square method. Thirdly, decomposes the coal-fired electric industry emissions of CO2,SO2 within a joint production framework.The results indicate mainly that their environmental technical efficiency is higher in coastal areas or those provinces rich in coal. However, the efficiency of whole country is deteriorating. Meanwhile, the environmental technical efficiency is lower than the technical efficiency, but more rational, and its changes can affect the manner of grown. The study also finds that capacity utilization rate, fuel efficiency and environmental have positive influence on environmental technical efficiency. Additionally, increasing emissions of CO2,SO2 are primarily associated with changes in the output mix. The end of paper will put forward several adives for improving the environment technical efficience and reducing emissions.
