As a major carbon emitter in China, the emission mitigation in industrial sector performs great significance for China to achieve its emission reduction targets. Using the provincial panel data during 2000-2016 of China's industrial sector, this paper first used a gravity model to study the spatial distribution and center of gravity of industrial CO emissions. Then, an integrated decomposition approach based on Shephard distance functions was adopted to study the driving factors of industrial carbon intensity. Results indicate that during 2000-2016, industrial CO emissions center of gravity gradually moved to the west. China's industrial carbon intensity achieved considerable decline, with the annual change rate of 8.27%. The energy intensity decline, technology progresses of both production and energy saving were the most important factors facilitating carbon intensity decline. However, energy structure adjustment exerted positive effects in carbon intensity increase, although its effects were minor. Industrial carbon intensity witnessed decrease in almost all provinces except Xinjiang. The effects resulted from various factors were also different across provinces. Finally, suggestions were proposed to further decrease industrial carbon intensity.
作为中国的主要碳排放国,工业部门的减排对于中国实现减排目标具有重要意义。本文利用中国工业部门 2000-2016 年期间的省级面板数据,首先使用引力模型研究了工业 CO 排放的空间分布和重心。然后,采用基于谢泼德距离函数的综合分解方法研究了工业碳强度的驱动因素。结果表明,2000-2016 年期间,工业 CO 排放重心逐渐向西移动。中国工业碳强度取得了显著下降,年均变化率为 8.27%。能源强度下降、生产和节能技术进步是促进碳强度下降的最重要因素。然而,能源结构调整对碳强度增加产生了积极影响,尽管其影响较小。除新疆外,几乎所有省份的工业碳强度都有所下降。各省因各种因素导致的效果也不同。最后,提出了进一步降低工业碳强度的建议。
