This paper, applying econometrics model method, makes an analysis on variable association between energy consumption and CO₂ emissions in material production process in the recent 30 years in China. The result indicates that: 1) The growth of energy consumption of material production departments and the rising movement of CO₂ emissions are affected predominantly by the energy consumption in material production process; 2) the energy consumption equilibrium in material production sector has been at a low level, energy consumption always maintained a high concentration on the specific industries, but the phasic variation also existed, that reflects the phenomenon: imbalance at low level→balance at low level→imbalance at higher level; 3) in material production sector, Tapio indicator of energy-GDP(TIEG) is in a cluster in the weak decoupling range, that indicates the rate of energy consumption growth is lower than the rate of economic growth largely, but the level of energy consumption efficiency still is behind the developed countries; and 4) the Tapio indicator distributions of CO₂-GDP(TICG) and TIEG are very similar, but Tapio indicator of CO₂-GDP(TICG) was more concentrated and decoupled. Finally, the paper puts forward the next direction and priority of the future work.
