摘要
文章利用中国家庭收入课题组2007年外来务工人员的个体调查数据,将贸易开放引入工时方程,实证研究贸易开放对农民工工时的影响程度、内在机制以及群体差异。研究发现,总体上贸易开放显著降低了农民工工时,进一步的计量分析确认了技术吸收能力作为贸易开放技术溢出的中间机制引起农民工工时下降。贸易开放对较高技能农民工工时的负向影响显著高于对低技能农民工的影响,这意味着高劳动强度的低技能农民工反而受到了更少的工时下降影响。文章指出,增强城市人力资本水平、提高农民工受教育程度是发挥贸易开放对农民工工时负向效应的关键。
Based on the individual survey of rural-to-urban migrant workers in China from the Chinese Household Income Project in 2007,this paper introduces trade openness into the working-hour equation and empirically analyzes the level,inherent mechanism and group differences of the effect of trade openness on the working hours of migrant workers. It comes to the results as follows:as a whole,trade openness significantly reduces the working hours of migrant workers;further econometric analysis confirms that technology absorptive capacity as an intermediate mechanism of technology spillover resulting from trade openness gives rise to the decrease in the working hours of migrant workers.The negative effect of trade openness on the working hours of highly skilled migrant workers is significantly higher than the effect on the working hours of migrant workers with low skill levels,showing that low skilled migrant workers with high labor intensity instead enjoy fewer benefits concerning the reduction in working hours.It points out that the increase in urban human capital level and the enhancement of education levels of migrant workers are the key to the exertion of the negative effect of trade openness on the working hours of migrant workers.
