The analysis of the dynamic evolution of the innovation efficiency of China' s new energy enterprises and its influencing factors helps to optimize the energy industry structure and provide feasible suggestions for the high-quality development of new energy enterprises under the guidance of dual carbon. This paper employs the SFA model to measure the innovation efficiency of new energy enterprises by considering their R&D investment and transformation processes. Additionally, it examines the convergence of innovation efficiency throughout 2015~2023. The threshold model is used to identify the main factors influencing the dynamic evolution of innovation efficiency. The results show that (1) The innovation efficiency of China's new energy enterprises is relatively low, with significant spatial and temporal differences but a consistent upward trend. Specifically, the innovation efficiency of China's new energy enterprises ranges from 0.55 to 0.71 in the R&D phase and from 0.13 to 0.51 in the transformation phase. ( 2) 1/3 of the new energy enterprises show a high R&D-high transformation mode, while another one-third operate under a low R&D-low transformation mode. The σ-convergence of innovation efficiency across provinces is not evident, except for the R&D phase of enterprises in the eastern and western regions, where substantial βconvergence is observed. (3) The threshold model suggests that urbanization construction and economic development play a crucial role in influencing the convergence of innovation efficiency among China's new energy enterprises.
