Atmospheric Environmental Efficiency Evaluation of China Based on DEA Method

Atmospheric Environmental Efficiency is a measure of the degree of economic growth and atmospheric pollution coordination. This article uses the 2006- 2012 panel data of 30 provinces,study atmospheric environmental efficiency, analyze the eastern, central, western and northeastern regions atmospheric environmental efficiency trends and regional differences,studies show: 2006- 2011 China Atmospheric environmental efficiency of the overall upward trend,in the eastern region the highest efficiency,lowest efficiency western regions,regional efficiency gap has expanded during2006-2011.
