数字化转型提升了绿色全要素能源效率吗?——来自中国A股工业上市企业的经验证据

Has Digital Transformation Improved Green Total Factor Energy Efficiency?

本文以2010—2021年中国A股工业上市企业为样本,运用EBM-GML模型对企业绿色全要素能源效率进行测算,并实证考察企业数字化转型对其提升效果的影响及作用机制。研究发现:数字化转型能够稳健且显著地提升企业绿色全要素能源效率,企业技术创新效率、管理效率在其中均起到中介作用;异质性分析发现,数字化转型对国有企业、“两高”企业、高新技术企业、东部及南部地区企业的绿色全要素能源效率的提升作用更为明显。因此,应重视数字化转型的战略价值,促进数字化加速融入能源管理体系;发挥数字化转型优势,赋能企业技术创新和管理优化;强化对企业数字化转型的引导和监督,推进数字化健康发展。

Taking China's A-share listed industrial enterprises from 2010 to 2021 as a sample,this paper uses the EBM-GML model to calculate the green total factor energy efficiency of enterprises,and empirically investigates the impact of enterprises'digital transformation on their improvement effect and its mechanism.It is found that digital transformation can steadily and significantly improve the green total factor energy efficiency of enterprises,in which the efficiency of enterprise technology innovation and management efficiency play an intermediary role.Heterogeneity analysis shows that digital transformation has a more significant effect on the improvement of green total factor energy efficiency in state-owned enterprises,"two high"enterprises and high-tech enterprises,and enterprises in the eastern and southern regions.Therefore,we should attach importance to the strategic value of digital transformation and accelerate the integration of digitalization into the energy management system;give full play to the advantages of digital transformation,and enable enterprises to make technological innovation and management optimization;strengthen the guidance and supervision of the digital transformation of enterprises,and promote the healthy development of digitalization.
