Analysis on inter-provincial energy efficiency difference and energy saving potential in China under carbon emission constraint

Wu Xiao-Hua

This paper analyzes inter-provincial energy efficiency and energy saving potential in China in 2010 based on DEA model. The research results indicate that the energy efficiency and energy saving potential in different areas are very different. The energy technology is low-efficiency in most areas in China due to massive investment redundancy, so the area differences should be fully considered when the energy saving and emission reduction targets are decomposed in provinces and the area targets should be reasonably set according to the phase of economy development level and current level of carbon emission. The research results can provide references for different economy policies set by area differences.
