『Abstract
Data envelopment analysis (DEA) has recently become a popular
method in measuring energy efficiency at the macro-economy level.
However, previous studies are limited in that they failed to consider
the issues of undesirable outputs and minimisation of energy consumption.
Thus, this study considers both factors in measuring Chinese industrial
energy efficiency and investigates the maximum energy-saving potential
in 28 administrative regions in China. The results show that industries
in the east area have the best average energy efficiency for the
period 2000-2006, followed by the central area. Further, after
comparing the industrial energy overall efficiency, pure technical
efficiency (IEPTE), and scale efficiency of the 28 administrative
regions examined, the study finds that in most regions of this
study, the two main reasons causing the wastage of a large amount
of energy during the industrial production process are that the
industrial structure of most regions still relies on the massive
use of energy in order to support the industrial-based economy
and the IEPTE is too low. Based on these findings, this paper
correspondingly proposes some policies to improve regional industrial
energy efficiency.
