摘要
本文搜集1978~2011年间的城镇居民家庭人均可支配收入的数据,通过建立自回归移动平均模型对其进行时序分析,并利用建立的模型预测2011年的人均收入,与2011年的人均实际收入进行比较,用以检验模型的拟合效果。分析结果表明,ARIMA模型能够提供较好的预测结果,因而可以用其进行预测,为相关部门提供参考数据。
This thesis collects the date of the per - capita disposable income of urban residents from 1978 to 2011 , and then to estab- lish a model which is used to forecast the per -capita disposable income of urban residents in 2011. And then,we can know the effect of the model by comparing the real per - capita disposable income of 2011 with the supposed per - capita disposable income of 2011 getting from the model. The result shows that: the model had a better effect, and therefore ,it can be used to offer some date for the related gov- ernment by forecasting the result.
