Abstract: The paper uses the 2011-2021 data of A-share listed companies in Shanghai and Shenzhen to empirically analyze the mechanism of green technology innovation of financial technology empowered enterprises. Research has found that financial technology helps companies innovate in green technology. Heterogeneity analysis shows that in state-owned enterprises, large-scale enterprises, non-heavily polluting industry enterprises, high-tech industry enterprises, high financial regulatory level enterprises, and enterprises in the central and western regions, financial technology has a higher empowering effect on green technology innovation in enterprises. The intermediary effect analysis shows that financial technology can promote green technology innovation in enterprises by alleviating financing constraints and enhancing environmental information disclosure. The analysis of regulatory effects indicates that environmental regulations, intellectual property protection, and corporate social responsibility play a positive regulatory role in the impact of financial technology on corporate green technology innovation. Further analysis shows that financial technology has the greatest promoting effect on green technology innovation in enterprises during the growth period, followed by the mature period, and is not significant during the recession period; financial technology has a positive spatial spillover effect on green technology innovation of enterprises in neighboring regions; financial technology has strengthened the role of green technology innovation in enhancing enterprise value.
