Recent developments in attaining carbon peaks and achieving carbon neutrality have had enormous effects on the world economy. Digitalization has been considered a viable way to curtail carbon emissions (CE) and promote sustainable economic development, but scant empirical studies investigate the link between digitalization and CE. In this context, this study constructs the digitalization index using the entropy value method and spatial Markov chain, and the spatial Durbin model is employed to analyze its impact mechanism and influence on urban CE in 265 prefecture-level cities and municipalities in China from 2011 to 2017. The results indicate that: (1) The overall development level of the digital economy (DE) posed a significant spatial effect on urban environmental pollution. However, the effect varies according to the different neighborhood backgrounds. (2) The DE impedes urban environmental deterioration directly and indirectly through the channels of industrial structure, inclusive finance, and urbanization. (3) The development of the DE significantly reduces pollution in cities belonging to urban agglomerations, while the development of the DE escalates emissions in nonurban agglomeration cities. Finally, based on the results, important policy implications are put forward to improve the environmental quality of cities.
近年来,实现碳峰值和碳中和的目标对世界经济产生了巨大影响。数字化被认为是减少碳排放(CE)和促进可持续经济发展的可行途径,但很少有实证研究探讨数字化与 CE 之间的联系。在这种情况下,本研究使用熵值法和空间马尔可夫链构建了数字化指数,并采用空间杜宾模型分析了其对中国 265 个地级及以上城市 2011-2017 年城市 CE 的影响机制和影响。结果表明:(1)数字经济(DE)的整体发展水平对城市环境污染具有显著的空间效应,但效应因不同的邻域背景而异。(2)DE 通过产业结构、包容性金融和城市化等渠道直接和间接阻碍了城市环境恶化。(3)DE 的发展显著降低了城市群城市的污染水平,而 DE 的发展则加剧了非城市群城市的排放。最后,根据研究结果,提出了重要的政策建议,以提高城市的环境质量。
