摘要

本研究以 2005-2021 年中国 283 个城市为样本，从城市群（UA）角度探讨数字金融（DIF）如何促进低碳发展。通过调节中介模型和多期差分模型，探讨了数字金融的潜在碳减排路径和城市群政策的调节机制。这项研究得出了一些有价值的可靠结论。首先，DIF 和 UA 政策促进了碳减排，但存在明显的地区差异。第二，绿色技术创新（GTI）和产业结构升级（ISU）在 DIF 对碳强度的影响中起着关键的负向中介作用。第三，UA 政策进一步增强了 DIF、GTI 和 ISU 的碳减排能力。第四，当DIF积极促进GTI时，UA政策会增强其作用，但当DIF积极促进ISU时，UA政策不会表现出调节作用。

Synergistic impact of digital finance and urban agglomeration policy on carbon emission reduction

This study employs a sample of 283 Chinese cities in 2005–2021 to investigate how digital finance (DIF) promotes low-carbon development from an urban agglomeration (UA) perspective. The moderated mediation and multiperiod difference-in-differences models are utilized to explore DIF's potential carbon emission reduction paths and the moderation mechanism of UA policies. This research yields some valuable and robust conclusions. First, DIF and UA policies promote carbon emission reduction with noticeable regional variations. Second, green technology innovation (GTI) and industrial structure upgrading (ISU) play a crucial negative mediating role in the impact of DIF on carbon intensity. Third, UA policies have further enhanced the carbon emission reduction capabilities of DIF, GTI, and ISU. Fourth, UA policies enhance their role when DIF positively fosters GTI but does not exhibit a moderating effect when DIF positively facilitates ISU.
