Regional characteristics of industrial energy efficiency in China: application of stochastic frontier

Tao HUANG,Akio ONISHI,Feng SHI,Masafumi MORISUGI,Mjo Lwin CHERRY

Frontiers of Environmental Science & Engineering 2015, Volume 9, Issue 3,   Pages 506-521 doi: 10.1007/s11783-014-0656-y

Abstract: This paper analyzed regional industrial energy efficiency in China with Total-Factor Energy EfficiencyCompared with the conventional energy efficiency, the inverse of energy intensity, which is defined asthe ratio of actual output to energy input, is regarded as Single-Factor Energy Efficiency (SFEE) indexThe SFEE scores could be over-estimated if energy is taken as the single input in the production.However, increasing of heavy industry will lead to worse industrial energy efficiency.
