Abstract

The low-carbon economy represents a global transformation that encompasses production methods, lifestyles, values, national interests, and the destiny of humanity. As a significant contributor to carbon emissions, China has made a momentous strategic decision on carbon peaking and neutralization, infusing momentum into the global effort to address climate change. The rapid growth of the digital economy offers a fresh approach to achieving the "double carbon" objective and advancing the development of low-carbon transformation. Based on the panel data of 30 provinces in China, this paper uses the least square method to investigate the impact of digital economy development on regional low-carbon inclusive development. It is found that there is a significant inverted U shape in the impact of the digital economy on low-carbon inclusive development and the mechanism is resource allocation and ecological inequality. The threshold test found that the role of the digital economy in promoting low-carbon inclusive development shows a marginal decreasing trend. The inverted U-shaped impact of the digital economy on low-carbon inclusive development in the eastern and coastal areas and areas with a low level of factor productivity is more significant. Based on the knowledge factor spillover perspective, we found that the impact of the digital economy on low-carbon inclusive development has a spatial spillover effect, and this effect is more obvious under the role of R&D personnel mobility.

摘要

低碳经济代表着一种全球性的变革,涵盖了生产方式、生活方式、价值观、国家利益和人类的命运。作为碳排放的重要贡献者,中国在碳达峰和碳中和方面做出了重大战略决策,为全球应对气候变化注入了动力。数字经济的快速增长为实现“双碳”目标和推进低碳转型发展提供了新途径。本文利用中国 30 个省份的面板数据,采用最小二乘法实证检验了数字经济发展对区域低碳包容性发展的影响。研究结果表明,数字经济对低碳包容性发展的影响存在显著的倒“U”型关系,其作用机制为资源配置效应和生态环境不平等效应。门槛检验发现,数字经济对低碳包容性发展的促进作用呈现边际递减趋势。数字经济对东部沿海地区和要素生产率水平较低地区低碳包容性发展的倒“U”型影响更为显著。基于知识溢出视角,本文发现数字经济对低碳包容性发展具有空间溢出效应,且这种效应在研发人员流动的作用下更为明显。
