这项研究调查了1998-2009年期间美国工业部门化学排放物毒性的变化。具体而言，我们采用了多地区投入产出分析框架，并整合了供应侧指数分解分析（IDA）和需求侧结构分解分析（SDA），以明确生产和消费型化学排放物毒性变化的主要驱动因素。结果表明，由于美国工业采取了污染减排措施，美国工业部门的有毒排放量在研究期间减少了83%。不同的工业采取了各种减少污染的措施，最重要的措施是采矿部门的清洁生产和运输设备制造中使用替代材料。
This study investigated the changes in the toxicity of chemical emissions from the US industrial sector over the 1998–2009 period. Specifically, we employed a multiregional input–output analysis framework and integrated a supply-side index decomposition analysis (IDA) with a demand-side structural decomposition analysis (SDA) to clarify the main drivers of changes in the toxicity of production- and consumption-based chemical emissions. The results showed that toxic emissions from the US industrial sector decreased by 83% over the studied period because of pollution abatement efforts adopted by US industries. A variety of pollution abatement efforts were used by different industries, and cleaner production in the mining sector and the use of alternative materials in the manufacture of transportation equipment represented the most important efforts.
