摘　　要：文章认为我国农村居民消费行为在不同时期存在显著差异,而传统计量经济模型是无法解释的。于是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我国农村居民可支配收入及消费支出之间的关系进行比较研究。并且分析了反映可支配收入与消费支出关系的时变边际消费倾向及弹性系数。This paper holds that traditional econometrics can not explain the obvious differences that have illustrated in the different periods to the consumption behaviors of the rural residents in our country.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 rural residents in our country through establishing nonparametric regression model and ordinary regression model,and then analyzes the marginal consumption inclination that varies with the change of time and elastic coefficient.
