中文摘要：

文章较为系统地分析了国际贸易、技术进步等因素对中国工业部门劳动收入份额的影响。研究显示在1999～2009年期间，我国工业部门的劳动收入份额总体上呈现出缓慢下降的趋势，工业部门劳动收入份额变动主要是行业内部劳动力再配置的结果；利用中国工业部门21个细分行业的面板数据，通过系统广义矩方法对国际贸易、技术变革对行业劳动收入份额的影响进行计量分析表明，国际贸易具有较为显著的提高我国工业部门行业劳动份额的效应，而技术进步则存在显著降低工业行业劳动份额的效应，这与我国工业部门在研究期内的技术进步具有劳动节约型特征有关。

英文摘要：

This paper systematically analyzes the impact of international trade and technological progress on the labor income share of China＇s industrial sector. Results of the research indicate that in the period between 1999 and 2009, the labor income share of China＇s industrial sector shows a slowly declining trend and the change of labor income share of industrial sector is mainly the result of labor reallocation within the industry. We employ the GMM econometric approach to estimate the effects of international trade and technological change on the industry labor share by using the panel data of 21 segmented industries within China＇s industrial sector between 1999 and 2007. The econometric analysis shows that international trade has a significant positive effect on the labor share of China＇s industrial sector, while technological progress has a significant negative impact on the industrial labor share, which is related to the labor-saving feature of the technological progress in China＇s industrial sector.
