Abstract: It has become an important issue in theory and reality to promote the deep integration of enterprise digitalization, intelligence and greening, and solve the dilemma of green innovation. Based on the listed companies in Shanghai and Shenzhen A-shares from 2014 to 2023, this study explores the impact and mechanism of digital intelligence on enterprise green innovation from the dual perspective of "improving quality and expanding quantity" as well as "enhancing efficiency". The results show that: (1) Digital intelligence can not only promote the quantity and quality, but also improve efficiency, and the conclusion still holds after testing for robustness. (2) The mechanism testing shows that digital intelligence breaks through the green innovation dilemma by optimizing the allocation of innovation resources and reducing information asymmetry and other means. (3) Heterogeneity analysis shows that high environmental regulation areas, high-tech industries, state-owned and large enterprises, digital intelligence plays a more significant effect on the improvement of the green innovation. (4) The effect consequences study shows that the promotion of enterprise green innovation by digital intelligence can further improve the economic, environmental, and social responsibility performance of the enterprise. The conclusion of this study provides useful insights for leveraging digital intelligence to drive enterprise green innovation, achieving the dual-carbon goals and boosting the overall performance of China's innovation system, and shaping new driving forces and advantages for high-quality development of enterprises.
