The oil and gas industry is an important basic energy industry in China, and its development is closely related to the improvement of comprehensive national power and quality of life. However, it is also a high energy consumption and high pollution industry, and the continuous input of various energy sources is often accompanied by damage to the surrounding environment. Therefore, it is important to evaluate the energy eco-efficiency of oil and gas enterprises for sustainable economic and social development. Based on both static and dynamic perspectives, this paper measures the energy eco-efficiency of 60 listed oil and gas resource-based companies from 2011-2019 using the SBM model and the Malmquist-Luenberger (ML) index model. The Tobit model is constructed to explore the influencing factors of energy eco-efficiency. The results show that the energy eco-efficiency of oil and gas resource-based enterprises shows a trend of rising and then falling, and there is much room for improvement. Among them, the energy eco-efficiency in the western region is basically consistent with the national average; technological progress has a greater impact on the energy eco-efficiency efficiency of oil and gas resource-based enterprises, while the role of technical efficiency is not significant; economic development, enterprise scale and technological innovation are positively and significantly related to energy eco-efficiency, however, energy consumption is negatively related to energy eco-efficiency.
