Carbon dioxide mainly comes from industrial economic activities. Industrial structure optimization is an effective way to reduce carbon dioxide emissions. This paper uses the panel data of 13 cities in the Beijing-Tianjin-Hebei urban agglomeration from 2006 to 2019, uses the Theil index to calculate the industrial structure rationalization index, and uses the proportion of industrial added value to calculate the industrial structure upgrade index. By constructing the STIRPAT model, this paper quantitatively analyzes the impact of industrial structure rationalization and upgrade on carbon emissions. The results show that the rationalization and upgrading of industrial structure in the Beijing-Tianjin-Hebei urban agglomeration significantly inhibit carbon emissions. Compared with the rationalization of the industrial structure, the upgrading of industrial structure in the Beijing-Tianjin-Hebei urban agglomeration has a better effect on carbon emission reduction. For the Beijing-Tianjin-Hebei urban agglomeration, government expenditure on science and technology can promote the upgrading of industrial structure to a certain extent, thereby reducing carbon emissions. There is a big gap between the industrial structure development level of Hebei province and that of Beijing and Tianjin. Finally, based on the conclusion, this paper puts forward the policy enlightenment of promoting the optimization process of industrial structure and reducing carbon emissions of the Beijing-Tianjin-Hebei urban agglomeration.
二氧化碳主要来源于工业经济活动。产业结构优化是减少二氧化碳排放的有效途径。本文采用京津冀城市群13个城市2006—2019年的面板数据，运用泰尔指数计算产业结构合理化指数，运用工业增加值比重计算产业结构升级指数。通过构建STIRPAT模型，定量分析产业结构合理化与升级对碳排放的影响。结果表明，京津冀城市群产业结构的合理化与升级显著抑制了碳排放。与产业结构合理化相比，京津冀城市群产业结构升级对碳排放的抑制效果更好。对于京津冀城市群而言，政府科技支出能够在一定程度上推动产业结构升级，从而减少碳排放。河北省产业结构发展水平与北京、天津存在较大差距。最后，基于研究结论，提出促进京津冀城市群产业结构优化进程、降低碳排放的政策启示。
