产业数字化对碳生产力的影响研究

Research on the Impact of Industrial Digitization on Carbon Productivity

在数字经济时代背景下,借助产业数字化平衡经济发展与碳排放之间的关系,对“双碳”目标的实现具有重要意义。本文基于2013~2021年的省级面板数据构建产业数字化水平指标体系,测度后实证探讨产业数字化对碳生产力的影响及作用机制,并多维度比较分析其影响差异。研究发现:产业数字化的发展能够显著促进碳生产力的提升,但该促进作用具有异质性。在中、西部和数字技术水平低的地区,产业数字化对碳生产力的提升作用更强;相比农业和工业数字化,服务业数字化对碳生产力的提升作用更显著。进一步的机制分析表明,产业数字化可通过促进绿色技术创新和优化能源消费结构推动碳生产力提升。本文为深入推进产业数字化的发展以及充分发挥其在实现“双碳”目标中的关键作用提供了理论指导及政策启示。

In the context of the digital economy,it is important to balance the relationship between economic development and carbon emissions with the help of industrial digitization(ID)to achieve the dual-carbon goals.Based on the provincial panel data from 2013 to 2021,this paper constructs the index system of ID,empirically explores the impact and mechanism of ID on car⁃bon productivity(CP),and comparatively analyses the impact differences from multiple dimensions.The study found that the develo⁃pment of ID can significantly promote CP,but this promotion effect is heterogeneous.In the central and western regions and regions with low digital technology level,ID has a stronger effect on CP improvement.Compared with the digitization of agriculture and in⁃dustry,the digitization of service industry has a more significant effect on CP.Mechanism analysis shows that ID can promote CP by promoting green technology innovation and optimizing energy consumption structure.This paper provides theoretical guidance and policy implications for further promoting the development of ID and giving full play to its key role in achieving the dual-carbon goals.
