贾尚晖教授与金佳宇助理教授以及博士生陈薪卉合作研究论文Digital disruption and energy efficiency: The impact of regional digitalization on China’s industrial sector发表在Energy期刊，该论文受到统计与数学学院科研团队项目基金支持。论文利用工业企业氮氧化物（NOx）和硫氧化物（SOx）排放微观数据，研究了数字化如何影响能源效率。实证结果表明，区域数字化可以显著促进工业企业能源效率的提高。具体而言，PSM-DID方法的结果显示，“国家创新试点城市”政策显著增强了数字化对能源效率的影响，而动态结果验证了工业企业能源效率的持续性。此外，区域数字化对东部地区企业、制造业以及流动性和盈利水平较高的企业的影响更为显著。最后，调节效应表明技术创新扩大了数字化对企业能源效率的正向影响。本研究证实了区域数字化可以促进中国工业企业能源效率的提高，并为中国能源转型提供了政策建议。

英文摘要：

Using the unique micro-data of industrial enterprises’ Nitrogen oxides (NOx) and Sulfur oxides (SOx) emissions covering 58,725 enterprise-year observations, this paper investigates how digitalization affect energy efficiency. The empirical results show that regional digitalization can significantly promote the improvement of energy efficiency of industrial enterprises. Specifically, the result of PSM-DID method indicates that the impact of digitalization on energy efficiency is significantly enhanced by the “National innovative pilot cities” policy, while the dynamic result validates the continuity of industrial enterprises’ energy efficiency. Moreover, regional digitalization has superior impact on enterprises within eastern region enterprises, the manufacturing sector, and with elevated liquidity and profitability levels. Finally, moderating effect suggests that technological innovation expand the positive impact of digitalization on enterprises’ energy efficiency. This study confirms regional digitalization can promote the energy efficiency of Chinese industrial enterprises, providing the policy suggestions to the energy transition in China.
