摘要
依据粮农组织数据库中给出的1961—2005年的中国牛肉产量数据为基础,分别通过差分把非平稳时间序列转化为平稳时间序列。建立了ARIMA(1,2,1)模型对中国牛肉产量进行预测。根据新华社对2006年中国牛肉产量的报道和德国莱茵农业协会对2007年中国牛肉产量的估计结果来看,ARIMA模型的预测误差只有1%左右,模型预测良好。
Based on the historical data of beef products from 1961 to 2005 that got from FAO DATA, this study transformed the nonstationary series to stationary series through differencing then constructed the ARIMA(1,2,1) model to forecast the beef products. Base on the report of Xinhua news agency of 2006 and the estimation of the Rheinland Agriculture of 2007 on the beef-product, we saw that the forecast error of ARIMA (1,2,1) model was 1%, the model was excellent.
