摘要

绿色金融政策是平衡环境和经济目标的关键纽带。本文采用2011 - 2022年城市面板数据，采用异中差模型研究绿色金融改革创新试验区对空气质量的污染减排效应及其机制。研究结果显示，试点政策显著降低了参与城市的PM2.5浓度，这一结果在多重稳健性检验下是稳健的。值得注意的是，数字技术的采用降低了绿色金融政策的减排效果，这可能是由于“规模扩张效应”和“长尾效应”。异质性分析表明，金融发展水平越高、环境监管越严格、产业结构合理化程度越低、大气污染越严重的地区，政策效力越强。这些结果为完善绿色金融方法、协调数字化和绿色转型提供了经验证据和政策见解。

Green finance innovation, digital technology, and air pollution

Green finance policies serve as a critical nexus for balancing environmental and economic objectives. In this study, city-level panel data from 2011 to 2022 is employed and a difference-in-differences model is used to investigate the pollution abatement effects of green finance reform and innovation pilot zones on air quality and the underlying mechanisms. The findings reveal that the pilot policies significantly reduced PM2.5 concentrations in participating cities, a result that is robust against multiple robustness checks. Notably, digital technology adoption reduced the pollution-reducing effects of green finance policies, potentially because of the “scale expansion effect” and “long-tail effect”. Heterogeneity analysis indicates stronger policy efficacy in regions with higher levels of financial development, stricter environmental regulations, lower levels of industrial structure rationalization, and more severe air pollution. These results provide empirical evidence and policy insights for refining green finance approaches and coordinating digital and green transitions.
