Abstract
This paper makes an analysis and evaluation of operating efficiency of Chinese Coal Mining Listed Companies from 2001 to 2010 by Data Envelopment Analysis. In the same time, it measures the changes of efficiency of coal mining industry by Malmqusit Productivity Index. The study demonstrates that those factors such as regional location and regional distribution have little effect on operating efficiency on this industry. The scale effect was formed, while technical efficiency is relatively low and unstable. And all efficiencies have been improved in 11 companies but MQH in these years.
