摘要: 本文以1973~2018年云南省总人口为例,分别建立Holt两参数指数平滑模型、ARIMA模型和三次多项式模型,利用最小AIC准则从ARIMA模型中选出了ARIMA(4,3,1)模型,与Holt两参数指数平滑模型和三次多项式模型做比较。通过模型预测值的平均误差率和残差的波动幅度的比较后,发现ARIMA(4,3,1)模型的拟合精度较高,适合用来预测短期的总人口数。基于此分析对云南省总人口进行了8期数的预测,发现云南省总人口数量呈现不断增加的趋势,但总人口数增长速率下降,总人口数量趋向饱和状态。

Abstract: Taking the total population of Yunnan Province from 1973 to 2018 as an example, this paper establishes the Holt two-parameter exponential smoothing model, the ARIMA model and the cubic polynomial model. The ARIMA (4,3,1) model is selected from the ARIMA model using the minimum AIC criterion and is compared with Holt's two-parameter exponential smoothing model and cubic polynomial model. After comparing the average error rate of the predicted value of the model with the fluctuation range of the residual, the ARIMA(4,3,1) model has a higher fitting accuracy and is suitable for predicting the total population in the short term. Based on this analysis, the total population of Yunnan Province was predicted for 8 periods.

Key words: ARIMA model, Holt two-parameter exponential smoothing model, cubic polynomial model, population forecasting, model comparison
