摘　　要：本文尝试用非参数回归方法研究居民人均可支配收入与消费的关系,应用非参数局部多项式估计方法对广西1980年~2010年城镇居民人均可支配收入与消费数据进行实证分析,克服了传统线性回归模型在讨论居民人均可支配收入与消费关系的不足。实证结果表明非参数回归方法优于线性回归方法.The paper attempts to introduce nonparametric regression estimation theory to study the per capita income and consumption relationship. Based on the data from the per capita income and consumption of Guangxi urban household from 1980 to 2010, we make empirical analysis with nonparametric local polynomial estimation method, and overcome the shortcoming of the traditional linear estimation method for the per capita income and consumption relationship. The result shows that nonparametric regression is superior to linear regression.
