本文利用时间序列的两种建模方法,通过对云南省1979年至2008年旅游外汇收入额(SRE)数据进行实证分析,分别建立了确定性时间序列指数模型和随机性时间序列ARIMA(1,2,1)模型,并对云南省2006年至2010年旅游外汇收入额进行了预测,得到两种模型预测误差都较小,但通过对比随机性时间序列ARIMA(1,2,1)模型拥有更高的拟合精度,能够很好的描述该序列特征,其预测结果可以为相关部门政策和规划的制定提供参考。

Using two kinds of time series modeling method to empirically analyze the tourist foreign exchange earning capacity (SRE) from 1979 to 2008 in Yunnan, we establish deterministic time series index model and stochastic time series ARIMA (1,2,1) model, and apply the models to forecast the tourist foreign exchange earning capacity from 1982 to 2010, The two models' error we get are both small ,but through the contrast the model ARIMA(1,2,1) has a higher fitting accuracy, it can be a good description of the time series characteristics and its forecast results can be used to provide reference for other relevant department policy and planning.
