Abstract:

Since the reform and opening up, China’s total energy intensity has shown an overall downward trend. It will contribute to promote energy conservation and emission reduction if we determine the factors influencing total energy intensity. Here we decomposed energy intensity into structural effects and efficiency effects,and analyzed reasons causing the decline in China’s total energy intensity and industrial energy intensity from the angles of each industry and industrial sectors based on structural decomposition analysis(SDA). We found that the decrease in China’s energy intensity was mainly due to improvements in energy utilization efficiency of the three major industries. However,the change in industrial structure hindered the drop in total energy intensity before 2013 and played a weak positive role after 2013. From the impacts of four industries on total energy intensity,the structural factor of Industry,Construction and Tertiary Industry had a negative impact on total energy intensity,which was greater than the positive impact of the Primary Industry. While the efficiency factor of Industry,Construction and Tertiary Industry predominantly led to the fall of total energy intensity in China. The decline in industrial energy intensity was jointly driven by change in the internal structure of Industry and the improvement of industrial sectoral energy utilizing efficiency,among which the decrease in industrial sectoral energy intensity played a leading role. From impacts of industrial sectors on industrial energy intensity,the influence of the structural effect and efficiency effect of industrial sectors was focused on several sectors. Change in the structure and efficiency of key high energy-consumption industries played an important role in promoting the decrease in industrial energy intensity. The influence of structural and efficiency change in some industrial sectors on industrial energy intensity has become increasingly evident. These industrial sectors have a relatively rapid pace of development. Based on these findings,some suggestions are put forward to provide support for formulating energy-saving strategies.
