新疆城镇居民人均可支配收入趋势的组合预测

A Combined Forecast of the Trend of Per Capita Disposable Income of Urban Residents in Xinjiang

为了分析新疆城镇居民人均可支配收入的变化趋势,利用1995~2018年新疆城镇居民人均可支配收入的数据,分别建立了ARIMA模型和指数平滑模型.利用这两个单项模型建立了城镇居民人均可支配收入的组合模型.实例结果表明:指数平滑模型的拟合效果优于ARIMA模型,而组合模型的拟合效果优于两个单项模型.最后,运用组合模型对未来五年新疆城镇居民人均可支配收入进行预测.

In order to analyze the change trend of per capita disposable income of urban residents in Xinjiang,ARIMA model and exponential smoothing model are established respectively by using the data of per capita disposable income of urban residents in Xinjiang from 1995 to 2018.And a combined model of per capita disposable income of urban residents is established based on the two single models.It is showed in the results that the fitting effect of exponential smoothing model is better than that of ARIMA model,and that of combination model is better than that of two single models.Finally,the per capita disposable income of urban residents in Xinjiang in the next five years is predicted based on the combined model.
