【Abstract】 This paper uses the multiple linear regression method to analyze the electric power consumption of Yunnan province for 26 years in the SPSS software. The regression model is established for five indicators of power consumption and significance test is implemented on this model. The results show that the model has substantial significance and can be used for practical prediction. The model has been applied in fitting historical data and the fitting effects are very good. The forecast of electric power consumption in 2011 and 2012 has resulted in accuracy over 85%. This model can provide certain reference values for related fields.更多还原
