最低工资标准提升的劳动供给效应——基于回归间断设计的经验研究

文章依据中国健康与营养调查1997～2009年的微观数据,应用回归间断设计方法分析了最低工资标准提升对低收入群体劳动供给的影响。研究结果表明,提升最低工资标准未对男性就业和工作时间产生显著的影响,也未对女性工作时间产生显著影响,但对女性就业产生了显著的消极影响,这导致女性劳动力供给明显降低。随着相对工资的上升,男性就业、男性工作时间和女性工作时间均呈现上升趋势。因此,政府应逐渐适度地提高最低工资标准,在保证低收入群体劳动供给不受较大消极影响的同时,渐进地提高低收入群体的工资水平。

Labor Supply Effects of Minimum Wage: An Empirical Research Based on Regression Discontinuity Design

In this paper,by using the micro datasets of China Health and Nutrition Survey from 1997 to 2009,we study the labor supply effects of minimum wage increase on low-income workers with a regression discontinuity design setting.The study has the following results.Increasing minimum wage hardly has significant impact on male’s employment and working hours.Although the increase has no impact on female’s working hours,it does have negative impact on female’s employment,and female labor supply is reduced as a result.The increase of employment and working hours of both males and females has occurred in tandem with the increase of relative wages.In conclusion,for lower income groups,increase of minimum wage should be a gradual process that minimizes the negative effects on low-income workers’ labor supply.
