Abstract: By taking pollutant emission and mine disaster into the analytical framework of the total factors productivity (TFP) with Malmquist-Luenberger index, this paper estimates TFP of 30 large-scale coal enterprises from 1998 to 2009 and empirically analyzes affecting factors to TFP. The result shows that most of enterprises have undergone negative growth in TFP When taking bad production into consideration, but the technology has significant growth. Under two different assumptions of environmental pollution and safety regulation, there are 14 and 16 enterprises had happened production possibility boundary expansion. Production efficiency is positively related to overall coal consumption per unit of GDP, technical reform and safety investment, administrative expenses rate, productivity index and technical inefficiency of lag period. There are inverted U-shape relationship between productivity index and Per Capita GDP, but production efficiency is negatively related to capital-labor ratio.
