This study aims to address the important question of whether the digital economy can be deeply integrated with the energy sector to break through the resource and environmental constraints and thus enhance the productivity of energy companies. Using a sample of Chinese energy-listed companies, we comprehensively investigate the impact of the digital economy on the productivity of energy firms using the OLS method, mediated effects model, instrumental variables method, and difference-in-differences model. Research shows that the development of digital economy can significantly improve the productivity of energy enterprises. This effect is more obvious in eastern cities, non-resource-based cities, state-owned enterprises, and enterprises with high cash holdings. Green technological innovation in alternative energy production, transportation, and administrative supervision and design is an important channel for improving productivity in the digital economy. Internet development and digital inclusive finance can also improve the productivity of energy enterprises. "National Big Data Pilot Zone" and "Broadband China" pilot cities can play a policy role in improving the productivity of energy enterprises. The findings provide important insights for promoting the integration of the digital revolution with the energy technology revolution and accelerating the green development and digital transformation of the energy sector.
本研究旨在探讨数字经济能否与能源部门深度融合，突破资源环境约束，从而提高能源企业的生产力这一重要问题。我们使用中国能源类上市公司的样本，综合运用 OLS 方法、中介效应模型、工具变量法和双重差分模型，全面考察了数字经济对能源企业生产力的影响。研究表明，数字经济的发展可以显著提高能源企业的生产力。在东部城市、非资源型城市、国有企业和现金持有量较高的企业中，这种效应更为明显。替代能源生产、运输以及行政监管和设计中的绿色技术创新是提高数字经济生产力的重要途径。互联网发展和数字包容性金融也可以提高能源企业的生产力。“国家大数据试验区”和“宽带中国”试点城市可以在提高能源企业生产力方面发挥政策作用。研究结果为推动数字革命与能源技术革命融合，加快能源部门绿色发展和数字化转型提供了重要启示。
