摘要
采用1993～2009年的数据，对我国外汇储备总量占国内GDP总量比重的变化走势进行了统计研究。利用线性模型和非参数回归模型，对我国外汇储备总量占国内GDP总量比重的变化走势进行了拟合分析。结果表明，我国外汇储备总量占国内GDP总量比重的变化走势大致呈线性增长。男外，从拟合效果来说，相对于线性回归模型而言，非参数回归模型更能有效地拟合该比重的变化走势，最后给出了建议。
In the article, by using 1993- 2009 data, the empirical analysis of the trend of the total foreign exchange reserves in China account for the proportion of domestic GDP is studied. Through the use of linear model and nonparametric re- gression model, the trend of the total foreign exchange reser＇~e account for the proportion of GDP is fitted. It can be concluded that the change has a roughly linear growth trend. In addition, relative to the linear regression model, the effect of the nonparametric regression model is significant. Finally, policy recommendations are given.
