Improving carbon productivity is of great significance to China's "30 · 60" carbon target, while the development of the digital economy is a driving force for green transformation. However, few studies discuss the relationship between the digital economy and carbon productivity. We investigate the influence of digital economic development on carbon productivity using panel data from 30 Chinese provinces from 2011 to 2020. Spatial econometric and moderating effects are considered. The results show that (i) digital economy has a positive direct and negative spatial spillover effect on carbon productivity, and this conclusion is still valid after the robustness test and endogeneity test; (ii) digital infrastructure has a greater impact on carbon productivity than digital industrialization and industrial digitalization; (iii) the mechanism analysis shows that environmental regulation negatively moderates the relationship between the digital economy and carbon productivity; (iv) heterogeneity analysis shows that the effect of the digital economy on carbon productivity is more obvious in the central region compared to the western region, while it is not significant in the eastern region. Overall, this paper not only provides a new analytical perspective for understanding the improvement of carbon productivity in the digital economy but also provides policy inspiration for promoting carbon peak and carbon neutrality goals.
提高碳生产力对中国的“30·60”碳目标具有重要意义，而数字经济的发展是绿色转型的驱动力。然而，很少有研究探讨数字经济与碳生产力之间的关系。我们利用 2011 年至 2020 年中国 30 个省份的面板数据，研究了数字经济发展对碳生产力的影响。考虑了空间计量经济学和调节效应。结果表明：（i）数字经济对碳生产力具有正向直接和负向空间溢出效应，这一结论在稳健性检验和内生性检验后仍然成立；（ii）数字基础设施对碳生产力的影响大于数字产业化和产业数字化；（iii）机制分析表明，环境规制负向调节数字经济与碳生产力之间的关系；（iv）异质性分析表明，数字经济对碳生产力的影响在中部地区比西部地区更为明显，而在东部地区则不显著。总体而言，本文不仅为理解数字经济中碳生产力的提高提供了新的分析视角，也为促进碳达峰和碳中和目标提供了政策启示。
