污染避难所假说是国际贸易环境效应的重要争论点，近年来全球生产分工格局明显改变。生产过程分布在全球，国际贸易的污染避风港效应变得更加复杂。例如，中间产品贸易所占的隐含排放份额最大，全球价值链相关贸易所导致的排放份额逐渐增加。本文旨在从全球、双边和国家角度对三种不同贸易模式所体现的碳排放污染避风港假说进行全面分析。我们提出了一种方法来包裹污染避难所假说在多区域的投入产出分析，并讨论了全球排放的生产碎片化的贡献。研究发现，国际生产分散化可以节省全球排放量。中间产品贸易在避免的排放量方面存在负平衡。1995-2009年期间，最终产品贸易的环境效益越来越低。不同的贸易模式对每个国家的环境影响有很大差异。
Pollution haven hypothesis is an important debate on the environmental effects of international trade, the pattern of which has been reshaped obviously by global production fragmentation recently. The production process is distributed globally, and the pollution haven effect of international trade is becoming more complicated. For instance, intermediate product trade corresponds to the largest share of embodied emissions, and the share of emissions induced by the global value chain related trade is increasing gradually. The aim of this paper is to make a comprehensive analysis on the pollution haven hypothesis in carbon emissions embodied in three different trade patterns from global, bilateral, and national perspectives. We propose a method to parcel the pollution haven hypothesis in a multi-regional input–output analysis and discuss the contribution of production fragmentation for global emissions. It is found that international production fragmentation generates global emissions savings. The intermediate product trade has a negative balance of avoided emissions. The final product trade becomes increasingly less environmentally effective during the period 1995–2009. There are significant differences in the environmental effects of different trade patterns for each country.
