ABSTRACT=Electrification is currently the most mature technological path to carbon neutrality. The traditional measurement methods of electrification level cannot meet the development requirements of China's electrification under the "dual carbon" strategy. Based on this, this paper incorporates carbon constraints into the re-electrification level evaluation system, and evaluate the re-electrification level of 30 provinces in China from 2007 to 2019 using entropy weight method. Then, the functional data analysis method is employed to further explore the dynamic variation rule of the regional re-electrification level. The evaluation results show that the top three provinces in the mean value of the re-electrification index are Guangdong (0.628), Jiangsu (0.617), and Zhejiang (0.573). The clustering results show that there are great spatial differences in the development of electrification in China. According to the fitted function curve, China's electrification development can be roughly divided into four stages: uptrend, brief decline, sharp uptrend, and slight and steady decline. At present, China's electrification is entering a new stage. In working to further deepening of re-electrification, the government and the power grid enterprises need to find the priority and breakthroughs under carbon emissions and environmental constraints. Our research results may provide reference for the improvement of regional re-electrification level in China.
