Abstract: Energy efficiency assessment based on the multiple benefits allows people to achieve economic growth while taking energy security, competitiveness, environmental, social and technological sustainability into consideration. This paper discusses the path of evolution and development of energy efficiency connotation, and extends energy efficiency connotation to multiple benefits. It takes non-parametric DEA method as an example, and researches the evolution of the trend of energy efficiency evaluation method based in multiple benefits. The paper puts forward that there are mainly three trends in the assessment of energy efficiency based on multiple benefits by using DEA:energy efficiency connotation continuously expands; DEA model turns to non-oriented and non-radial model; the dimensions of assessment of energy efficiency continues to expand. Comprehensive index evaluation system and evaluation method of energy efficiency based on multiple benefits will be further studied.
