In this paper, 29 provincial-level administrative units of 1995-2007 data. The effects of FDI inflows through technology spillover effects on China's energy intensity. The results show, FDI inflows to some extent to reduce China's energy intensity, but not statistically significant. This shows that FDI inflows did not have a spillover effect of energy conservation in China. In order to improve energy efficiency in developing countries including China, developed countries should increase energy conservation technology transfer efforts. Developing countries should strengthen independent innovation, increased research and development spending to increase the capacity to absorb foreign advanced technologies.
