高校毕业生供给的增加对大学工资升水率的影响

    摘要：我国自1999年以来实施的高校扩招政策使得进入劳动力市场的受过高等教育的年轻劳动者数量迅速增加，大学毕业生工资产生了下降的趋势。特别在年轻群体中，这一现象表现的尤为明显。本文借鉴国外学者的两阶段模型，利用中国1989~2009年的数据检验了大学毕业生总体供给的相对改变对其相对收入的影响，并进一步给出了大学和高中两个受教育组劳动者之间的替代弹性。

    Abstract: China has begun expanding higher education since 1999. The policy of expansion caused the number of younger educated labor rapidly increased, and affected college wage premium. Following Card and Lemieux’s two-step model with the data set from 1989 to 2009, this paper examines the effect of changes in relative supply of our college graduate workers on their relative wages and further investigates the elasticity of substitution between college and high school cohorts.
