中文摘要：

提升制造业出口贸易品技术含量是中国由“制造大国”向“制造强国”转型的关键所在。文章采用Hausmann等（2007）所修正的出口技术复杂度指数来测度中国制造业1995～2012年出口贸易品技术含量的变化轨迹。发现中国制造业出口贸易品技术含量上升趋势明显，目前已处于世界前列，其中纺织服装、机械与电子设备制造业尤其突出。进一步分析发现，人力资本、进口贸易、外商直接投资和对外直接投资均能显著提升中国制造业的出口贸易品技术含量，而传统的劳动力要素和资本要素对中国制造业出口贸易品技术含量无显著影响。

英文摘要：

Enhancing the technological content of manufacturing export goods is the key to the transformation of China from ＂a big manufacturing country＂ to ＂a strong manufacturing country＂. This paper uses the index of export sophistication revised by Hausmann et al （2007） to measure the changing trajectory of technological content of China＇s manufacturing export goods from 1995 to 2012, and finds that the technological content of China＇s manufacturing export goods rises significantly, now ranking in the forefront of the world, especially textiles and clothing, machinery and electronic equipment manufacturing industries. Further analysis reveals that human capital, import trade, foreign direct investment and outward direct investment can significantly improve the technological content of China＇ s manufacturing export goods, while the traditional elements of labor and capital have no significant effects on the technological content of China＇s manufacturing export goods.
