摘要
利用时间序列分析的ARIMA模型对甘肃省1985—2007年的能源需求总量进行了实证研究,结果表明甘肃省能源需求总量在做短期预测时ARIMA(0,2,1)模型是合理的,在此基础上做了预测,并得出来相应结论。
ARIMA model is applied which is the method of establishing time-series to empirically analyze Gansu energy demand from 1985 to 2007. The analysis shows that ARIMA(0,2,1 ) is efficiency. Based on this,a short- time predication and researches conclusions are made of.
