To achieve the goal of green development and low-carbon development, the Chinese government has proposed a series of high-quality development and energy efficiency improvement measures. This study constructs two data envelopment analysis (DEA) models using meta-frontier methods to analyze China's regional and provincial energy efficiency. Compared to traditional DEA models, the proposed models not only integrate technical-level disparities between different regions but also consider integer constraints on variables. The empirical results reveal that there is still great potential for optimization in China's energy efficiency. There are serious development imbalances in energy efficiency and technology levels in different regions of China. In addition, the efficiency optimization space of each region is discussed from the viewpoints of technology and management. The results show that most provinces need to improve efficiency in terms of management, technology, or both.
