Abstract: Considering the current energy efficiency calculation hasn't included the grey haze as the environmental constraint, a Nonseparable Hybrid DEA Model is constructed based on the non-parametric frontier. Taking SO2, NOx, CO2, smoke(dust) who cause haze as undesirable output of energy consumption, the provincial energy efficiency in 2010-2013 under haze environment constraint is measured more scientific. The result suggests that: difference of provincial energy in China is significant; energy efficiency in the eastern China is the highest, followed by central China and western China is the worst; the overall energy efficiency in China is 0.63. Then the influence factors of energy efficiency are analyzed through Tobit model and it is found that energy endowment, industrial structure, the government influence have significant negative effect on energy efficiency, and technological progress has significantly positive effect on energy efficiency. The influence degrees of various factors varies on eastern, central, western China are different. From the perspective of energy conservation and emissions reduction potential, potential of energy saving and pollutants caused haze reduction are both huge. Research results will help different provinces to establish energy saving and gray haze management planning.

Key words: haze, energy efficiency, NH-DEA, multiple undesirable output, energy conservation and emissions reduction
