“农二代”城镇层级流动对打工收入增长的影响

The Influence of City Level Difference on Income Growth of the Second-Generation Migrant Laborers

利用全国性大样本调查数据构建多层次Mincer打工收入扩展方程。实证分析发现,"农二代"与城市同龄人具有趋同价值观和个人发展诉求,"农二代"不同层级城镇打工对收入增长产生不同影响,省会及以上城市收入增长影响效果较好,而地级市及以下较差。城镇层级与人力资本等级产生收入增长联动影响,高层级城镇对高人力资本收入增长具有积极影响,而对低人力资本则具有消极影响。高知识技能农民工因其异质性适合在较大范围内流动,而低知识技能农民工因其同质性应适当控制流动距离,更多进入地级及以下城镇打工。当前"农二代"城镇层级流动格局尚存在优化空间,政策应扶持家庭创业和多元经营以支撑中小城市和小城镇的产业发展。

With the multi-level Mincer expansion equation about wages and revenue with the nationwide large sample survey data,the findings show that the 'second-generation migrant laborers'have the same values and appeals with their urban contemporaries.Different levels of their working cities will have different effects on their income growth.Their income growth is better in the provincial or above cities,while worse in cities lower than prefecture level.There is a coordinated effect on income growth between city levels and human resource levels.Higher level cities have positive effect on the growth of higher level human capital and negative effect on lower level human capital.The current flow between different town levels should be further optimized.Policies should focus on supporting the family business and the diversified management to support the development of industry of small and mediumsized cities and small towns.
