Environmental pollution and climate change have become nontraditional global security threats. As China's economy grows, the country faces an increasing number of challenges associated with improving atmospheric quality and reducing greenhouse gas emissions. Based on China's dynamic noncompetitive input-output tables and data on energy consumption and emissions from 1994 to 2016, a hybrid input-output model is constructed to identify high-energy-consuming sectors and to quantify the impact of industrial restructuring on the intensity of air pollutant and greenhouse gas emissions from these sectors. The empirical results indicate that the impact of industrial restructuring on the intensity of air pollutant and greenhouse gas emissions from high-energy-consuming sectors was nonlinear and has undergone a "promotion reduction" shift. This study also found that the impact of industrial restructuring is more significant on the intensity of greenhouse gas emissions than on the intensity of air pollutant emissions; furthermore, the reduction in greenhouse gas emission intensity achieved by industrial restructuring after 2008 began to show results. Based on the findings of this study, we make recommendations such as the need for the Chinese government to continue to promote supply-side structural reforms in the energy sector.
环境污染和气候变化已成为非传统的全球安全威胁。随着中国经济的增长，该国面临着越来越多的挑战，需要改善空气质量并减少温室气体排放。本研究基于中国动态非竞争投入产出表以及 1994 年至 2016 年的能源消费和排放数据，构建了一个混合投入产出模型，以识别高能耗部门，并量化产业结构调整对这些部门的空气污染物和温室气体排放强度的影响。实证结果表明，产业结构调整对高能耗部门的空气污染物和温室气体排放强度的影响是非线性的，并经历了“促进-减少”的转变。本研究还发现，产业结构调整对温室气体排放强度的影响大于对空气污染物排放强度的影响；此外，2008 年之后产业结构调整对温室气体排放强度的减排效果开始显现。基于本研究的结果，我们建议中国政府继续推进能源部门的供给侧结构性改革。
