我国城镇居民消费的非参数回归模型

Nonparametric Regression Model of Chinese Urban Resident Consumption

基于传统的计量经济模型无法解释我国城镇居民消费在不同时期存在着显著差异这一特点,利用非参数估计理论中的多项式样条估计方法对我国城镇居民可支配消费和支出之间的关系进行研究,建立了我国城镇居民消费的非参数回归模型。模拟结果表明,非参数回归模型优于线性回归模型。

The conventional metering economic model can not explain the consumptive diversity of the residents in the town in different periods,this paper trys to use the ploynomial spline estimation of nonparametric estimation to compare the relation between dominate consumption and payout of the residents.A nonparametric regression model is introduced to the dominate consumption and payout of the residents.The result shows that nonparametric regression model is more applicable compared to linear regression.
