中文摘要：

随着生产过程跨国分散化愈演愈烈，国家之间的“垂直专业化”程度加大。很多产品的生产不再局限于某个国家或某个企业，其整个生产过程分散为由不同的国家或地区来完成，由此为原有以出口量为基础的显示性比较优势的测度方法带来一定挑战。本文利用国际投入产出表。引入国家之间的进出口联系，计算以收入为基础的比较优势，得出发达国家通过技术控制和输入，从我国高技术产品出口中受益，降低了我国高技术产业的收益率和比较优势。因此，需要加强高技术产业的自主创新能力，提升产业的竞争力。

英文摘要：

International vertical specialization of production is deepening with the fragmentation of production processes between countries. The production is not limited in one nation or one company. The production process is separated in different countries and areas. Therefore, the revealed comparative advantage index, based on export volume, face a lot of challenges. International input-out- put table is used in this article to measure the national comparative advantage, based on revenue, considering the international relation- ship of import and output. After analysis, it is concluded that developed countries have benefited from the export growth of China＇s high- tech industries, with control and import of critical technologies. And it reduced the revenue and comparative advantage of China＇s high- tech industries. So it is imperative to develop the endogenous innovation of these industries.
