利用1997年—2009年中美双边贸易数据和美国制造业行业数据,分析了中美双边贸易对美国制造业技能工人和非技能工人工资溢价的影响,发现中美双边贸易整体上拉大了美国制造业行业工资溢价,然而进口和出口分别对工资溢价产生不同的影响。进一步将制造业行业分为中高技术水平和中低技术水平,结果显示美国从中国的进口拉大了美国中高、中低技术行业技能劳动力和非技能劳动力的工资溢价,然而美国向中国的出口分别对于中高、中低技术行业的工资溢价产生相反作用。 Based on the data of bilateral trade between China and the United States from 1997 to 2009 and the data of the U.S. manufacturing industry, this paper analyzes the impact of bilateral trade between China and the United States on the wage premium of skilled workers and unskilled workers in the United States and finds that the bilateral trade between China and the United States as a whole has greatly increased the U.S. The manufacturing industry wage premium, however, imports and exports have different effects on wage premiums. Further dividing the manufacturing industry into medium and high-tech industries and low-medium-tech industries showed that the U.S. imports from China widened the wage premiums on skilled and unskilled labor in the middle and low-tech industries in the United States. However, the U.S. exports to China were respectively For the high, low-tech industry wage premiums have the opposite effect.
