摘要
The purpose of this paper is to investigate the driving force behind industrial energy productivity growth in China from 2005 to 2010. The model of Wang (Energy, 32(8), 1326-1333, 2007) is extended to accommodate different technologies by relaxing the constant return to scale (CRS) assumption. In the empirical study, we find that (1) technological changes and capital-energy substitution are the main contributors to the increase in industrial energy productivity; (2) impacts of changes in technical efficiency, energy composition, and output structure are relatively trivial; (3) the effect of labor-energy substitution is unfavorable to industrial energy productivity growth.
