In the context of environmental sustainability and accelerated digital technology development, China attaches great importance to the prominent role of digital economy in addressing environmental degradation. Utilizing Chinese provincial panel data from 2011 to 2019, this study investigates whether the digital economy can improve China's environmental sustainability proxy by reducing carbon emission intensity. Based on the fixed effects model, the findings reveal that the digital economy has a significant negative effect on carbon emission intensity and the conclusion remains robust after conducting several robustness checks. However, this impact shows regional heterogeneity, which is more effective in resource-based eastern regions and the Belt and Road provinces. Moreover, mediating effect analyses indicate that the transmission mechanisms are energy consumption structure, total factor energy productivity, and green technology innovation. Furthermore, the results based on the spatial Durbin model (SDM) demonstrate that digital economy development has a significant spatial spillover effect. Finally, on the basis of results analysis and discussion, policy recommendations are provided for achieving environmental sustainability.
在中国重视环境可持续性和加速数字技术发展的背景下,中国高度重视数字经济在解决环境退化方面的突出作用。本研究利用中国 2011 年至 2019 年的省级面板数据,探讨数字经济是否可以通过降低碳排放强度来提高中国环境可持续性的代表性。基于固定效应模型,研究结果表明,数字经济对碳排放强度有显著的负向影响,且在进行了几次稳健性检验后,结论仍然稳健。然而,这种影响表现出区域异质性,在资源型东部地区和“一带一路”省份更为有效。此外,中介效应分析表明,其传导机制是能源消费结构、全要素能源生产率和绿色技术创新。此外,基于空间杜宾模型(SDM)的结果表明,数字经济发展具有显著的空间溢出效应。最后,在结果分析和讨论的基础上,提出了实现环境可持续性的政策建议。
