On the Interpretation and Measurement of Technology-Adjusted Emissions Embodied in Trade
提出一种将生产技术标准化到世界平均水平的新方法，用于衡量净弱碳泄漏，即出口避免的国外排放与进口产生的国外排放之差，并基于全球多区域投入产出表分析了1995-2015年49个经济体的时空变化。
Abstract We propose a new method for standardizing the production technology at the world average level and derive interpretations for the resulting carbon emission concepts. The technology-adjusted emission balance measures net weak carbon leakage defined as the difference between the foreign emissions avoided by exports and the foreign emissions generated by imports. We use global multi-regional input–output tables to document the variable’s spatio-temporal variation for 49 economies between 1995 and 2015. There is a positive cross-country correlation between net leakage and per-capita income. Changes in net leakage are generally small and do not account for country-specific emission trends, that is, domestic emission decreases were not offset by foreign emission increases.
