| 摘 要： | 近二十多年来，非参数统计的方法已广泛应用于计量经济学的研究。由于不需要预先确定变量间的函数关系，对计量经济模型的估计和预测提供了多方面和灵活机动的表现形式。本文尝试将非参数估计理论引入到回归模型中，通过建立非参数回归模型及普通的线性回归模型对云南省城镇居民可支配收入及消费之间的关系进行比较研究。

| Abstract: | From hst decade,nonparametric statistical methods have been widely used in economentrics,since they offer versatility and flexibility in estimation and forcecastingone needs not to specify functional forms.This paper attempts to introduce nonparametric estimation theory and carries out a comparative study on the relationship between income that can be dominated and consumption for the town residents in Yunnan province through establishing nonparametric regression model and ordinary regression model. |
