This article applies a parametric metafrontier method and the Malmquist index to analyze the energy efficiency and its dynamic performance in China’s commercial sector from 1995 to 2013. The results indicate that the energy efficiency in China’s commercial sector is generally low, and there are significant regional differences and enormous energy-saving potentials. Relative to metafrontier, commercial sectors in eastern China have relatively higher energy efficiency; while those in central and western China have relatively low energy efficiency. Besides, the dynamic energy efficiency performance in China’s commercial sector has improved over the period. The technology improvement is a major driving factor to improve the energy efficiency in the commercial sectors of all the three regions.
