Abstract:  Data envelopment analysis，which grows from the concept of relative efficiency evaluation, is an effective method to evaluate decision making units with same kind of input and output. With the data set collected from 1998 to 2008, the total factors energy efficiency of Hebei Province is analyzed by using the superefficiencyDEA model extended from C2R model. In the analysis, energy consumption, labor force and capital stock are the input indexes, while GDP is the output index. Based on an empirical analysis, it is shown that although there is significant improvement in energy efficiency during 1998 to 2008, there is large distance to the expected goal. Based on the results, some suggestions are proposed to increase energy efficiency of Hebei Province.  

Key words:  superefficiencyDEA model, total factors, energy efficiency
