Based on the panel data of patent intensive-industries from 2007 to 2016, this paper utilized the Biennial Malmquist-Luenberger (BML) productivity index method to measure and decompose the energy efficiency. The results showed thatthe energy efficiency of patent-intensive industries showed growth trend on the whole and its growth rate was higher than non-patent-intensive industries and the overall industry. Besides, the contribution of structure effect (SE) was the largest and that of total factor productivity (TFP) was the least.Moreover, different industries had different sources of energy efficiency growth. For most industries, technical change (TC), labor-energy substitution effect (LE), and output structure effect (OSE) increased energy efficiency. Therefore, it is necessary to further accelerate the pace of energy conservation, optimize the industrial structure, promote technological progress, and increase the substitution effect of labor on energy for patent-intensive industries.
