本文阐述了分析农民工流动问题的意义,认为目前对农民工流动的研究大多都是从农民是“理性经济人”身份出发的,不能充分反映农民工流动的实质。作者以文化融合和理性农民视角分析讨论农民在其迁移选择过程中的各种因素:城乡差距、利益追求、生存安全等,试图以社会学生存伦理角度探究农民工迁移的主体性原因。 This paper expounds the significance of analyzing the problem of migrant workers’ mobility and thinks that the current researches on the migrant workers’ mobility are mostly based on the fact that the farmers are “rational economic persons” and can not fully reflect the essence of migrant workers’ mobility. Based on cultural integration and rational peasants’ perspective, the author analyzes and discusses various factors of peasants in the process of migration choice: urban-rural gap, interest pursuit, survival and security, and tries to explore the subjective reasons of peasant-worker migration from the perspective of social ethics.
