Abstract

Green technological innovation serves as an effective instrument for achieving a balance between high-quality economic development and ecological environmental governance. Using the new energy demonstration city policy (NEDCP) as a quasi-natural experiment, this study employs a Propensity Score Matching–Difference-in-Differences (PSM-DID) approach to assess the impact of the NEDCP on urban green technological innovation (UGTI) across 282 Chinese cities. The empirical analysis draws the following conclusions. The NEDCP significantly promotes UGTI, a conclusion substantiated by multiple robustness tests. The heterogeneity outcomes show that NEDCP can have varying effects on UGTI depending on a city's initial level of green technology development, geographic location, and classification. The mechanism analysis demonstrates that NEDCP enhances UGTI by improving energy utilization efficiency. Ecological resilience weakens the effectiveness of NEDCP in promoting UGTI. These results provide theoretical and empirical support for refining the NEDCP and offer new insights for advancing regional sustainable development.
