中文摘要：

利用2012年全国流动人口动态监测数据、2013年西安交通大学＂新型城镇化与可持续发展＂课题组深圳调查数据,基于新型城镇化背景,结合十大阶层理论,调整社会阶层划分方法;透过横向、纵向两个维度,户籍、代际、代内三重视角,综合考察农民工的社会分层与流动现状。分析结果显示：农民工阶层结构呈＂金字塔型＂,普遍分布于蓝领、雇员阶层;多数农民工通过进城务工实现上升流动,城镇打工期间则以平层流动为主;农民工阶层体系的平等性、公平性和开放性虽有较大改观,但与城镇居民尚存一定差距。当代农民工群体已经分化,＂社会封闭＂＂阶层固化＂＂结构化与再生产＂趋势初步显现,＂碎片化＂和＂集团化＂特征尚未出现。据此,提出相应的政策建议。

英文摘要：

The purpose of this paper is to investigate the social stratification and social mobility of contemporary rural migrant workers,through two dimensions of horizontal and vertical as well as triple perspectives of hukou,intra and inter generations.Based on the background of New-type urbanization,the paper improves the approach of social class division with the theory of ＂Ten Classes＂.Using the data of National floating population dynamic monitoring of 2012 and the data of Shenzhen surveyed by the research group of ＂New-type urbanization and sustainable development＂ of Xi＇an Jiaotong University in 2013,the analysis results indicate：the rural migrant workers＇ class structure as＂Pyramid＂,their distribution lies generally in the ＂blue collar＂or/and＂employees＂class.While most of the rural migrant workers ascend in social stratification via going to cities for employment,during the period of work the mobility remains in the same class as they are.Although the equality,equity and opening of stratification system have been improved a lot,the gap also lies between citizens and migrants.It is concluded that the group of rural migrant workers is in process of dividing,the tendency of social closure,structuration and stratum reproduction is already happening,but the character of fragment and collective has not shown.Finally,some policy suggestions have given.
