Based on the panel data of 284 prefecture-level cities in China, this paper uses the dynamic spatial Durbin model to explore the impact of digital finance on green innovation from the dimensions of "quantity" and "quality." The results show that digital finance has a positive impact on both the quality and quantity of green innovation in local cities, but the development of digital finance in neighboring cities has a negative impact on the quantity and quality of green innovation in local cities, and the impact on the quality of green innovation is greater than that on the quantity of green innovation. And after a series of robustness tests, it was shown that the above conclusions are robust. In addition, digital finance can have a positive impact on green innovation mainly through industrial structure upgrading and informatization level. Heterogeneity analysis shows that the breadth of coverage and the degree of digitization are significantly related to green innovation, and digital finance has a more significant positive impact in eastern cities than in mid-western cities.
基于中国 284 个地级市的面板数据，本文利用动态空间 Durbin 模型从“数量”和“质量”两个维度探讨了数字金融对绿色创新的影响。结果表明，数字金融对本地城市绿色创新的数量和质量均有正向影响，但相邻城市数字金融的发展对本地城市绿色创新的数量和质量有负向影响，且对绿色创新质量的影响大于对数量的影响。经过一系列稳健性检验，证明了上述结论是稳健的。此外，数字金融可以通过产业结构升级和信息化水平对绿色创新产生积极影响。异质性分析表明，数字金融的覆盖广度和数字化程度与绿色创新显著相关，数字金融在东部城市比在中西部城市对绿色创新的正向影响更为显著。
