中国行业显性比较优势分析——基于国际投入产出关系的测算

随着国际产业分工不断深化，传统基于出口额计算的显性比较优势指数已不能反映真实的行业竞争力。运用WIOD数据，本文采用投入产出分析方法测算行业的出口增加值，并基于出口增加值计算中国各行业的显性比较优势。计算结果与基于出口额的传统方法有较大差异：具有竞争优势的行业数量下降，行业分布状况与竞争优势的动态变化不同，传统方法夸大了行业的优势程度或劣势程度。

Analysis on the Industrial Revealed Comparative Advantage of China on the Base of International Input-output Relationship

With the deepening of international specialization,revealed comparative advantage index of industry based on exports can not reflect the true competitive advantage.This article recalculates Chinese industrial revealed comparative advantage index based value-added exports,which is computed by using the international input-output analysis method on the data of WIOD.The result is different with that of traditional method based on exports:the number of industry with competitive advantage declines,the distribution of industry with competitive advantage and their dynamics are different,and that the traditional method overstates the degree of industrial advantage or disadvantage.
