Green finance policy is recognized as a critical bridge between finance and the environment, serving as a significant driving force for green innovation and green development. Data from 3462 listed manufacturing enterprises in China between 2000 to 2024 were utilized. A difference-in-differences (DID) model was employed to examine the impact of the 2012 "Green Credit Guidelines" on green technology innovation. The implementation of the "Green Credit Guidelines" is found to significantly improve the level of green technology innovation in manufacturing enterprises. Specifically, it promotes an increase in the number of green utility model patent applications, while its effect on enhancing green invention patents is not significant. Compared to non-state-owned manufacturing enterprises, the policy has a more pronounced effect on state-owned manufacturing enterprises. Compared to manufacturing enterprises in the central and western regions, a stronger effect is observed on manufacturing enterprises in the eastern region. The mechanism analysis indicates that green finance policy facilitates green technology innovation by alleviating corporate financing constraints, broadening access to external financing, and reducing financing costs. Policy recommendations are proposed from three perspectives. For commercial banks, green credit product innovation should be accelerated and green credit services optimized. For the government, the green finance system should be improved. For enterprises, strategic goals for green development should be established.
