摘要: 在实现碳达峰碳中和的关键时期,充分发挥数字创新优势,提升全要素碳排放效率至关重要。文章采用2009—2021年中国272个城市面板数据,以数字经济相关专利表征数字创新水平,考察了数字创新对全要素碳排放效率的影响。研究发现:(1)数字创新显著提升了全要素碳排放效率,并通过了排除政策影响、工具变量等稳健性检验。(2)异质性分析发现,在中部地区,数字创新对全要素碳排放效率的影响显著为正,但在东部地区和西部地区这种促进作用并不显著。在省会城市和非省会城市,数字创新对全要素碳排放效率均存在促进作用,并且在省会城市这种促进作用更为明显。(3)机制分析发现,数字创新显著促进了产业结构转型升级、加快了绿色创新步伐、提升了环境规制强度,从而促进了全要素碳排放效率的提升。研究回答了数字创新对全要素碳排放效率的影响及机制,为加快数字创新步伐,提升全要素碳排放效率,促进经济社会发展全面绿色低碳转型提供了参考。

Abstract: In the critical period of achieving carbon peaking and carbon neutrality, leveraging the advantages of digital innovation to enhance total factor carbon emission efficiency is crucial. This paper employs panel data from 272 Chinese cities spanning from 2009 to 2021, using patents related to the digital economy to represent the level of digital innovation, and examines the impact of digital innovation on total factor carbon emission efficiency. The findings are as follows: (1)Digital innovation significantly improves total factor carbon emission efficiency, and this result is robust to policy influence exclusion, variable replacement and instrumental variable tests. (2)Heterogeneity analysis reveals that in the central regions, digital innovation has a significantly positive impact on total factor carbon emission efficiency, whereas in the eastern and western regions, this promotion effect is not significant. Both in provincial capitals and non-provincial capitals, digital innovation promotes total factor carbon emission efficiency, with a more pronounced effect in provincial capitals. (3)Mechanism analysis indicates that digital innovation significantly promotes industrial structure transformation and upgrading, accelerates the pace of green innovation, and enhances the intensity of environmental regulation, thereby improving total factor carbon emission efficiency. This study addresses the impact and mechanisms of digital innovation on total factor carbon emission efficiency, providing valuable insights for accelerating digital innovation, improving total factor carbon emission efficiency, and promoting a comprehensive green and low-carbon transformation of economic and social development.

Key words: digital innovation, total factor carbon emission efficiency, carbon peaking and carbon neutrality
