The energy efficiency DEA method in value of economic continuity
Energy is of vital importance to economic development in every country nowadays. With the worldwide decreasing trend of energy reserves growth rate, energy efficiency is receiving more and more attentions. This paper focuses on improving the total factor energy efficiency DEA method from the respective of reverse thinking in order to analyse the results in value of economic continuity, and to calculate the TFEE of countries in time series. This paper takes the top ten energy consuming countries in 2011 as examples, and compares the results between the traditional and the improved methods respectively. The results show that energy efficiency calculated from traditional method could be overestimated, and the changing trends of energy efficiency in different periods could not be reflected by the traditional method.
