The heterogeneities of production technology among provinces in China cause difficulties for unbiased evaluation of energy efficiency. Using meta-frontier data envelopment analysis (DEA) approach, this paper proposes a new method for measuring energy efficiency by considering the “technology...

Data envelopment analysis (DEA) has been widely used for environmental performance measurement at different levels. Most of environmental DEA models take the deterministic form without considering random factors. This paper presents a stochastic environmental DEA model that can measure...
