Abstract :
Based on statistical data of National Statistical Bureau of China, and giving the least-squares fitting of Chebyshev polynomial, the data of energy consumption per capita from 1983 to 2008 is analyzed by GM (1,1) method and Chebyshev polynomial least squares method respectively. The results showed that Chebyshev polynomial least squares fitting method is excellent, per capita energy consumption from 2009 to 2013 is predicted by this method.
