中国零部件贸易比较优势与技术含量：结构与演变研究

基于中国5位数分类349种零部件产品的比较优势与技术含量指数,考量中国零部件产品出口与技术结构的演化特征,结果显示:中国零部件产品的比较优势与出口技术含量均有所提高,其中,高技术含量零部件产品出口竞争力提升尤为显著。结论表明,中国零部件贸易正在经历从低技术含量零部件产品出口到高技术含量零部件产品出口的出口转化阶段。中国零部件的出口结构仍然存在很大的改进空间。

Comparative Advantage and Technical Content of China's Parts Trade: Structure and Evolution

Parts trade has constituted an important part of China commodity trade. Based on SITC 5 digit classification, this paper calculated the index of comparative advantage and technical content of all 349 parts products. The result shows: in recent years, the comparative advantage of China''s parts trade and its export technology content have increased fast, especially so does the competitiveness of high technology parts product. The conclusions of this paper show that, Chinese parts trade is experiencing a transformation stage from the low technology parts exports to the high technology parts products export. The article also shows, although the technology content of China''s parts export is increasing faster than the growth of world parts export technology in the same period, but the average technical content of Chinese parts is still lower than the average technology content of the world parts trade. The results show that there exists big room for improvement in the export structure of Chinese parts trade.
