本文借助当代中国社会流动研究的成果探讨大学生就业难的问题。通过理论和实例分析,本文认为,当前大学生就业难具有阶层上的特殊性,政府在解决当代大学生就业难问题时应当充分考虑此特殊性,有针对性地制定政策,促进低阶层子女的向上流动。实施“岗位改造工程”是政府当前可以采取解决大学生就业难的比较有效的措施。 This article uses the research results of social mobility in contemporary China to probe into the problem of employment difficulties for college students. Through the theoretical and practical analysis, this paper argues that the current college students employment difficulties have the particularity of the class. The government should take full account of this particularity when it comes to solving the employment problems of contemporary college students and formulate policies to promote the upward mobility of the children in the lower grades . The implementation of “post renovation project ” is the government can take more difficult measures to solve the employment of college students more effective measures.
