SPECIAL ISSUE： MIGRANT WORKESR IN THE COURSE OF URBANIZATION Factors influencing the migration intentions of rural workers in the Pearl River Delta

在中国城乡户籍制度存在的背景下，什么因素影响农民工选择城市户籍，做出永久性迁移的决策，是本文关注的问题。研究发现，如果以是否愿意放弃土地作为行为性永久迁移意愿的指标，那么影响农民工迁移意愿的主要因素是个体的迁移动力，是一个基于经济理性的选择；如果以是否愿意将户口迁入打工城市作为制度性永久迁移意愿的指标，那么影响农民工迁移意愿的主要因素则相对集中在地域性因素和制度合法性压力上，是农民工寻求制度保障来改变城市生活境遇的社会理性选择。在不同迁移意愿的人群中，个体迁移动力与制度合法性压力作用是不一样的。

The focus of this article is this question： under China＇s present household registration system, what factors influence migrant workers＇ decisions to obtain urban household registration in order to stay permanently in the city？ Our research finds that if willingness to give up their land is used as the indicator for behavioral permanent migration, the main factors that influence migrant workers＇ intention to migrate will be their individual motives for migration, i.e. choices based on economic rationality. If wishing to transfer their household registration to the cities where they work is used as the indicator for institutional permanent migration, the main factors that influence their intentions will be regional conditions and the pressure of institutional legitimacy, and their choices will be socially rational in that they are seeking institutional protection to improve their life in the city. Groups with different aspirations vary in their individual motivations for migration and the degree to which they feel the pressure of institutional legitimacy.
