Abstract: It is showed that the school attendance rate of left-behind Children drops sharply once they reach the high school age according to the 2010 population census data. The social status of high school-aged left-behind children changes to new generation migrant workers if they join in the migration flow after their dropout. This paper proposes 3 hypotheses to test the effects of left-behind experiences and age at migration on their current income based on the Dynamic Supervision Survey of Floating Population conducted by the State Family Planning Commission in 2011. Results demonstrate that both the left-behind experience in earlier childhood and the age at migration significantly affect new generation's income. The correlation between age at migration and income also explains why left-behind children intend to stop schooling in high school.

摘要： 数据分析表明: 农村留守儿童进入高中学龄阶段后，教育机会急剧下降。受父母外出流动影响，高中学龄农村留守儿童终止学业后很快就外出打工，身份过早地从“农村留守儿童”转换为“新生代农民工”，很有可能对其未来发展带来负面影响。为了对高中学龄农村留守儿童终止学业的影响做深入研究，文章利用“2011 年流动人口动态监测数据”，通过构造以平均月收入对数为因变量的6 个线性回归模型对新生代农民工的留守经历、外出年龄等自变量与当前收入之间的关系进行论证，回归结果证明: 留守经历、外出时间以及二者交互作用对新生代农民工的收入都有显著影响。根据研究得到的留守经历与收入之间的互动关系，还可以对该年龄段农村留守儿童教育机会急剧下
降现象做出新的解释。
