On the basis of the review of some researches on social stratification and housing resource，this paper，first of all，discusses the relationship between housing and social stratification，and gets a conclusion that house has surely become one important symbol of social stratification. This paper then uses the Binary Logistic Regression model to analyze the influence of ascribed factors and self-actualized factors on urban youth’s obtaining of housing and concludes that apparent advantages lie with young people to obtain housing who meet one of three conditions，coming from general counties or cities，being Beijing locals，and having a weathy family. Though the youth are able to accomplish upward social mobility by accepting high quality elite education，whether they can accept elite education is affected by some ascribed factor in the first place. From all above，we infer that ascribed factors still have an influence on the youth’s social stratification，and social hierarchical system is consolidated to a certain extent.
