摘　　要：本文从“干中学”视角出发构建两期生产模型分析工作时间对工资率增长的影响。基于CLDS个体追踪数据的实证研究发现,我国城镇雇员的工资率增幅与其工作时间之间存在“倒U型”的函数关系。在每周工作时间小于41.476小时的情况下,工资率增幅会随着工作时间的延长而上升;而在工作时间超过这个阙值以后,工资率增幅则会随着工作时间的延长而下降,说明过度超时工作是缺乏效率的。进一步研究发现,女性、高学历、非农户籍、第三产业、私有部门及小型单位雇员的最优工作时间较短。研究说明合理的工时安排有助于提升劳动生产率,制定灵活的工时制度是实现高质量发展的内在要求。We analyzes the impact of working hours on wage rates growth from the perspective of"learning by doing".The empirical results based on CLDS show that there is an“inverted U-shaped”functional relationship between the urban employees’wage rates growth and their working hours.When the weekly working hours are less than 41.476 hours,the wage rates growth increases with the extension of the working hours,and when the working hours exceed the threshold,the wage rates growth decreases with the extension of the working hours,which indicates that the excessive overtime work is inefficient.Further research shows that the optimal working hours are shorter for female,higher educational,non-agricultural household registration employees,and those who work in tertiary industry,private sector or smaller organizations.The research shows that scientific working hours arrangement helps to improve labor productivity,and a more flexible working time system is an intrinsic requirement for high-quality development.
