本文将两条研究路线整合到一个统一的概念框架中：全球价值链中的贸易和隐含排放。这使得可以通过各种生产网络路线在国家、部门和双边各级系统地追踪增值和排放。通过以一致的方式将增值和排放核算相结合，可以估算沿着全球价值链的潜在环境成本（每单位增值的排放量）。使用这种统一的核算方法，我们追踪了1995年至2009年全球生产和贸易网络中41个经济体35个部门的二氧化碳排放量，并以世界投入产出数据库为基础进行计算，并展示了它们如何帮助我们更好地了解跨国生产共享对环境的影响。
This paper integrates two lines of research into a unified conceptual framework: trade in global value chains and embodied emissions. This allows both value added and emissions to be systematically traced at the country, sector, and bilateral levels through various production network routes. By combining value-added and emissions accounting in a consistent way, the potential environmental cost (amount of emissions per unit of value added) along global value chains can be estimated. Using this unified accounting method, we trace CO2 emissions in the global production and trade network among 41 economies in 35 sectors from 1995 to 2009, basing our calculations on the World Input–Output Database, and show how they help us to better understand the impact of cross-country production sharing on the environment.
