Abstract: In order to overcome the problem of heterogeneity of production technology in the past regional economic research, the SBM Undesirable model and Metafrontier production function are applied to calculate the ecological total factor energy efficiency of 30 provinces in China during 2004-2014 .At the same time, the paper uses “common technical ratio” to measure the technological gap of energy utilization in different regions, and analyzes the sources and influence factors of energy inefficiency from “management inefficiency”and “technology inefficiency” two dimensions. On the whole, there exist obvious regional differences in the common frontier ecological total factor energy efficiency (MTE) and common technical ratio (MTR)in the three groups of China, showing the “East-Middle-West” descending pattern; in three groups, the ranking of the group frontier ecological total factor energy efficiency (GTE) from high to low is West, Middle and East; from the decomposition of the mean value of ecological total factor energy efficiency, the inefficient energy use in the eastern group is due to the inefficiency of management, in central group the inefficiency of technical and management are both significant, while in the western group technical inefficiency is the most obvious, the industrial structure, opening up, R&D investment, environmental regulation, government intervention have significant and different impacts on the ecological total factor energy efficiency.

Key words: ecological total factor energy efficiency, SBM-Undesirable model, common frontier function model, common technical ratio
