The primary purpose of this dissertation is to analyze the supply and demand of energy in China by utilizing an input-output-analysis. The energy input-output table used in this dissertation was combined with other data from the Energy Statistics Yearbook of China to draw up a hybrid-unit input-output table diagram and its simulation analysis. According to the data, the shortage in China¡¦s electric-producing sector in 1997 had the strongest impact on the total output of China¡¦s economy. Over the years, electric producers have been gradually playing a vital role as China¡¦s main energy source. The analysis also pointed out that China¡¦s energy industry was insignificant prior to 1997, mainly due to government price regulation. This dissertation is therefore expected to identify a new path in the study of energy demand and supply in China.
