The influential factors of China's regional energy intensity and its spatial linkages: 1988-2007

► I discuss the regional differences and spatial linkages of China's energy intensity. ► The influential effect of seven factors on energy intensity is empirically tested. ► There exist positive spillover effect between the eastern and western China. ► There exist absolute and conditional β-convergence of energy intensity. ► Narrowing the regional gaps is a promising way for reducing China's energy intensity.
