摘要 立足中国2009—2021年31个省(区、市)面板数据,利用空间误差模型分析数字新基建、绿色技术进步对低碳经济转型的影响。结果显示:数字新基建与绿色技术进步均对低碳经济转型发挥显著推动作用,且二者与低碳经济转型之间存在显著空间关联性,该结论在经过一系列稳健性检验后依然成立;同时,数字新基建水平提升能够增强绿色技术进步对低碳经济转型的赋能效应;分样本研究结果表明,数字新基建与绿色技术进步对低碳经济转型的促进作用存在明显区域异质性,具体表现为东部地区显著而中西部地区不显著;门槛效应检验显示,绿色技术进步在数字新基建、低碳经济转型之间发挥门槛效应,在跨越门槛值后,东、中、西部地区数字新基建对低碳经济转型的助力作用均明显增强,且在西部地区更为显著;数字新基建的三层子维度均有利于低碳经济转型,其中融合基础设施建设的正向赋能效应最强。

Abstract: Based on panel data from 31 provinces and cities in China from 2009 to 2021, this paper use spatial error model to empirically analyze the impact of digital new infrastructure and green technology progress on the transformation of low-carbon economy. The research results indicate that both digital new infrastructure and green technological progress play a significant role in facilitating the transition to a low-carbon economy. Moreover, there is a significant spatial correlation between the two factors and the transition to a low-carbon economy. And this conclusion holds true even after a series of robustness tests. At the same time, the improvement of digital new infrastructure level can enhance the empowerment effect of green technology progress on low-carbon economic transformation. The results of sub-sample study show that there is obvious regional heterogeneity in the promoting effect of digital new infrastructure and green technology progress on the transformation of low-carbon economy, which is significant in the eastern region and not significant in the central and western regions. The threshold effect test shows that green technological progress plays a threshold effect between digital new infrastructure and the transformation to a low-carbon economy. After crossing the threshold, the assistance of digital new infrastructure in the low-carbon economy transformation has significantly increased in the eastern, central, and western regions, with a more significant effect observed in the western region. The three sub-dimensions of digital new infrastructure are conducive to the transformation of low-carbon economy, among which the positive enabling effect of integrated infrastructure construction is the strongest.
