摘　　要：目前,信息消费已成为日益增长的消费热点,是扩大内需的有效途径,对中国城乡居民信息消费的边际消费倾向变化规律的探讨显得尤为重要。对城乡居民的信息消费支出与收入变量进行协整检验的结果表明,二者虽然均为同阶单整序列,但不存在协整关系,不能采用线性回归方法得出结论。采用非参数回归方法的实证分析表明,城乡居民信息消费的边际消费倾向均呈倒U型曲线变化规律。虽然信息消费支出随收入的增加而增加,但这种增加幅度近期呈下降态势,说明居民的信息消费意愿不断下降。Information consumption of urban and rural residents is becoming the hotspots in China.It will be the valid approach to enlarge domestic demand.The changing law of marginal consumption propensity is studied in this paper.Firstly,the relationship of information consumption expenditure and income is tested by the method of co-integration.The conclusions show that the expenditure and income are the same rank integration time series.But two variables have not formed long-run co-integration relationship,so the linear regression methods cannot be used.Then the empirical conclusions are studied by the method of nonparametric regression.The results show that there has inverse'U'changing law of marginal consumption propensity.The information consumption expenditure has the increasing tendency,but its increasing rate is declining.The residents' aspiration of information consumption is weakening.Finally,two suggestions to increase the information consumption are put forward.
