Abstract: Based on total-factor production theory, a non-parametric frontier is constructed by Data Envelopment Analysis (DEA). Under the framework of meta-frontier, the analysis and comparison have been made on the regional disparities of China's total-factor energy efficiency during the period of 2000-2007. Additionally, a quantitative Technology Gap Ratios (TGR)-based analysis has been made on the technology gap on regional energy utilization in China. The conclusions are as follows: The overall level of China's total-factor energy is on the low side during the sample period, its average value is only 0.688 under countrywide meta-frontier and thus energy-saving potential could be increased by 31.2% in order to maintain the present economic output. There are significant regional disparities in energy technology and risk of further expansion of the energy technology gaps among three major areas. In east area of China, the TGR stays at above 95% and approaches the optimal nation level. In central area and west area of China, comparing with optimal national level, there are improvement potentials of 18.6% and 26.6%, respectively.

Key words: total-factor energy efficiency, energy technology, meta-frontier, regional disparitiy, TGR
