农村劳动力迁移摩擦影响农民工数量与工资结构吗?

Does the migration friction of rural labor affect the structure of rural migrant labor's quantity and wage?

运用世代交叠模型研究了迁移摩擦对城乡劳动力迁移结构变迁的长期动态特征影响.研究表明,在城乡劳动力市场分割的前提下,迁移成本、城镇失业人员的工资和暂时性迁移工人的工作摩擦共同刻画了中国城乡劳动力迁移的动态变化特征.当迁移摩擦变化时,农村迁移人员会理性地调整对教育的投资,进而会影响到迁移人员的教育结构和数量结构,而教育投资函数的凹函数性质和迁移人员风险厌恶的特征使得技术工对迁移摩擦变动更敏感,引起技术工的劳动供给更明显的变化,进而引起技术工工资更明显变化,为"迁移之谜"出现提供了可能.改善迁移人员的住房条件、医疗保障服务和完善劳动力市场机制,从而降低迁移成本、增加暂时性迁移工人的就业概率,是加快中国城乡迁移进程和解决中国"迁移之谜"的有效政策.

The paper, using overlapping generations model, studies the impact of migration friction on the long-term dynamic evolution process of rural-urban migration. It shows that migration costs, the urban unem- ployment insurance, and search matching friction shape the basic characteristics of rural-urban migration if there is segmentation in Chinese labor market. The rural migrations will adjust the investment in education ra- tionally when migration friction changes. The quantities of technical workers will be more sensitive to the chan- ges of migration friction because education investment is a concave function and migration labor is risk averse. Tile more sensitive changes in the quantity og technical workers will lead to the more sensitive changes in sala- ry, and the riddle of migration may result. Improving the housing and medical insurance of migrants and la- bour market mechanism will reduce the migration cost, raise employment probability of temporary workers, and will accelerate China＇ s urban-rural migration and be an effective policy to solve the riddle of migration in China.
