This research aims to study the effect on industrial carbon intensity by decomposing electricity consumption into electricity consumption volume and electric power intensity by using panel data of 27 China's manufacturing sectors. An improved STIRPAT model is also developed by this article to identify the unexplored potential influencing factors. The research findings suggest that there exists a long-run equilibrium relationship between electricity consumption and carbon intensity and unidirectional causality from electricity consumption volume to carbon intensity. Regression results indicate that electricity consumption volume has a significantly negative effect on industrial carbon intensity for the full sample. However, due to the significantly positive influence that electric power intensity has on carbon intensity, we conclude that energy consumption and industrial economy failed to achieve the decoupling effect. The impacts of electricity consumption volume and electric power intensity have industrial heterogeneity. Electric power intensity impacts carbon intensity the most for resource intensive sectors. The effects of subgroups are further examined for sectors with high/low carbon emission volume and carbon intensity. Foreign direct investment (FDI) is conducive to reducing carbon intensity for sectors with high volume and sectors with high intensity. Industrialization level demonstrates a significantly positive effect on improving carbon intensity for sectors with low volume and sectors with low intensity. Finally, we put forward specific suggestions on the basis of these empirical findings.
本研究旨在通过将电力消费分解为电力消费总量和电力强度,利用中国 27 个制造业部门的面板数据,研究电力消费对工业碳强度的影响。本文还开发了一种改进的 STIRPAT 模型,以识别尚未探索的潜在影响因素。研究结果表明,电力消费与碳强度之间存在长期均衡关系,电力消费总量对碳强度存在单向因果关系。回归结果表明,在全样本中,电力消费总量对工业碳强度有显著的负向影响。然而,由于电力强度对碳强度有显著的正向影响,我们得出结论,能源消耗和工业经济未能实现脱钩效应。电力消费总量和电力强度的影响具有产业异质性。电力强度对资源密集型行业的碳强度影响最大。对高/低碳排放量和碳强度的部门进行了子组影响的进一步检验。外国直接投资(FDI)有利于降低高排放量和高强度部门的碳强度。工业化水平对提高低排放量和低强度部门的碳强度具有显著的正向影响。最后,我们根据这些实证结果提出了具体建议。
