摘要
中国对美国高新技术产品出口呈现波动性增长,金融危机更暴露了出口增长面临外部冲击的脆弱性。利用2003-2009年HS\|8位数贸易数据,文章分解了中国对美国高新技术产品出口的增长结构,结果显示:无论从整体角度还是从具体技术类别角度,中国对美国高新技术产品出口增长均沿着集约边际实现,扩展边际的贡献较小,在提高出口临界值时,扩展边际所占比重提升也较为有限。内部出口结构失衡以及扩展边际的有限发展,成为中国对美国高新技术产品在低技术水平上大幅度波动增长的主要原因。因此,中国应该努力实现从集约边际向扩展边际的转变,调整出口结构,以提升出口产品的技术水平。
Export growth of China＇s high-tech products to the U.S.is volatile,especially when China export growth faces the external shock such as financial crisis.Using the HS-8 trade data from 2003 to 2006,this paper analyzes the structure of China＇s high-tech exports to the U.S..The results indicate that China export growth of high-tech products to the U.S.mainly depends on the intensive trade margin,and the extensive trade margin is very little.When the threshold value rises,the extensive trade margin changes very little.So the unbalance of exports structure and the limited expansion of the extensive trade margin are the main reasons for China＇s export volatility in high-tech products.Therefore,China should turn to the extensive trade margin from the intensive trade margin and adjust the export structure to enhance the technical level of high-tech products.
