基于样本分层的吉林省城镇居民收入消费差异研究——以长春市和四平市为例

Differences in Income and Consumption of Urban Residents in Jilin Province Based on Stratified Sample

2003-2007年,我省60%的城镇居民工资收入低于全省平均水平,在岗职工平均收入只达全国职工平均工资收入的一半,按统计样本各占20%分组的五个收入组年度平均收入差距较大,而按实际工资收入抽样样本各占10%分组的十个组别贫富差距加大,从而导致在食品等八个消费项目的消费水平高低差距拉大。

60% of urban residents＇ wage income in Jilin Province is lower than the provincial average wage from 2003 to 2007.The average income of on-the-job workers only reaches half of the national workers＇ average wage income.According to statistical samples,five income groups which take up 20% of the whole show the relatively large difference in average income,while the ten groups which take up 10% of the whole display the big gap between the rich and the poor.Thus,a big difference has been formed in consumption level regarding to the eight consuming items including food.
