全球价值链能准确测量增加值贸易吗

Can the Global Value Chains Measure the Trade in Value Added Approximately?

全球价值链作为分析价值创造的国际扩张、地域分布以及捕获的一种重要方法,被经济学研究者、政策制定者们广泛采用。本文针对研究者们在全球价值链视角下采用世界投入产出表(WIOD)数据库或相类似数据的测量误差展开深入的分析,为随后研究使用该种类型数据进行经验研究以及政策探讨提供了严谨性方面的参照。本文通过简单的两国情形下数值例证、一般性探讨以及进一步讨论,发现针对世界投入产出表进行增加值测算所隐含的测量误差相对突出。

The global value chain is an important method to measure the international expansion,geographical distribution and value capture of the value creation,which is used widely by the economic research-ers or the policy makers.This paper discusses the measurement errors by using the world input-output table or other related databases from the perspective of the global value chains,which supports the precise reference for the future researchers to explain their empirical results or policy implications accurately.The results show that the measurement errors are relatively prominent by the numerical two-country examples,general modes and the further discussion.
