Evaluation of the Influencing Factors of Energy Consumption in China's Energy-Intensive Industries

摘要

This manuscript aimed to seek influencing factors of energy consumption in China's energy-intensive industries employing the generalized logarithmic mean Divisia index (LMDI) and input-output analysis. The research stated clearly that decomposition factors covered energy structure, energy intensity, industry structure, complete demand, final demand structure, and final demand total effect. The results showed that the decrease of energy consumption in energy-intensive industries heavily relied on energy intensity and industry structure. However, final demand total effect, which specifically involved the investment demand and export expansion, was a dominant element driving energy consumption growth. Accordingly, speeding up the industrial structure adjustment, improving the import and export mix, and reducing energy intensity have been the primary approaches to decrease energy consumption in energy-intensive industries. These approaches would accelerate the target of a 16% decline in energy intensity compared with 2010 in China's Twelfth Five-Year Plan. Moreover, this research has crucial theoretical and practical significance on the implementation of energy policy in China. (C) 2017 American Society of Civil Engineers.
