Structural Decomposition of China’s Energy Use during 2000-2011 with World Input Output Table (WIOT) Data

By using world input output table data, this paper has divided the change of energy consumption into 5 effects: energy efficiency, intermediate input structure, export, investment and consumption. Results shows that the average growth rates of energy consumption embodied in consumption, investment and export during the analysis period are different. The evolution path of energy embodied in export and investment are almost the same during 2000 to 2007 and then dispersed because of global crisis in 2008. Changes of energy efficiency decreased the energy consumption in China while changes in production structure and total volume of final demands both contributed to the increase of China’s energy consumption.
