Abstract: In the context of China’s high-quality economic development, in-depth research on green innovation efficiency and its influencing factors is crucial for promoting economic transformation and energy conservation. This study employs the Hybrid Data Envelopment Analysis (DEA) method to measure the green innovation efficiency of 30 provinces in China from 2013 to 2019. Subsequently, based on the Multilevel Mixed-Effects (MME) Tobit model and a spatial econometric model, the study investigates the factors influencing green innovation efficiency under the backdrop of high-quality development, and conducts various robustness tests from different perspectives. The results indicate the following: Firstly, the overall level of green innovation efficiency in China is relatively low, but it shows a steady growth trend, with significant differences in green innovation efficiency among provinces in different stages of high-quality development. Secondly, the level of digital economic development, optimization of industrial structure, scale of knowledge dissemination, and degree of openness to the outside world have significant positive effects on green innovation efficiency. On the other hand, the scale of technological innovation, degree of environmental regulation, and guarantee of green innovation have significant negative effects, and the low quality of technological innovation hinders the improvement of green innovation efficiency. Thirdly, the new factors emerging under the backdrop of high-quality development exhibit certain spillover effects on green innovation efficiency. The green innovation efficiency of a province may be influenced by relevant factors in neighboring provinces. This provides new insights for provinces to enhance their green innovation efficiency. The contribution of this study lies in the incorporation of newly emerged factors in the context of high-quality development into the evaluation framework of green innovation efficiency. It accurately measures the green innovation efficiency of each province in China and, based on the analysis of influencing factors, provides novel insights for enhancing green innovation efficiency across provinces.
