摘要

数字化转型与碳中和的协同发展是实现全球可持续发展的关键路径。本研究利用 "宽带中国 "试点政策和多期差分法(DID)设计,使用中国291个地级市2008-2021年的面板数据,全面评估了数字基础设施对碳中和的影响。结果表明,区域数字基础设施促进了试点地区的碳中和创新、碳密集型产业创新和碳排放效率。在使用倾向得分匹配、粗略精确匹配、稳健估计器和工具变量回归分析结果后,这一结论依然成立。具体而言,中介效应模型的结果表明,数字基础设施通过促进产业结构合理化、推动数字经济发展、诱导数字技术创新等几种机制推动碳中和进程。此外,经济发展较好、资源依赖度较低、环境约束较弱的城市,其区域数字基础设施带来的碳中和红利效应更大。这些发现表明,有必要优化政策,释放数字基础设施在碳中和方面的红利,通过数字赋能推动技术、结构和效率变革。此外,具有不同禀赋的城市需要制定有针对性的措施。

Regional digital infrastructure and carbon neutrality: A technology–structure–efficiency perspective
The synergistic development of digital transformation and carbon neutrality is a key path to global sustainable development. This study utilized the Broadband China pilot policy and a multi-period Difference-in-Differences (DID) design to comprehensively evaluate the impact of digital infrastructure on carbon neutrality using panel data from 291 prefecture-level cities in China from 2008 to 2021. The results indicate that regional digital infrastructure contributed to carbon neutralization innovation, carbon-intensive industry innovation, and carbon-emission efficiency in the pilot areas. This held true after analyzing the results with propensity score matching, coarsened exact matching, robust estimators, and instrumental variable regression. Specifically, the results of the mediation effect model indicate that digital infrastructure promotes the process of carbon neutrality through several mechanisms, including promoting the rationalization of industrial structure, promoting digital economic development, and inducing innovation in digital technology. In addition, cities with better economic development, lower resource dependence, and weaker environmental constraints have a greater carbon neutrality dividend effect from regional digital infrastructure. These findings indicate a need to optimize policies to unleash the dividends of digital infrastructure in carbon neutrality, which can drive technological, structural, and efficiency changes through digital empowerment. In addition, cities with heterogeneous endowments need to develop targeted measures.
