数字经济对区域低碳节能发展的影响研究
Study on the Impact of Digital Economy on Regional Low-Carbon and Energy-Saving Development

在“双碳”背景下，数字经济成为经济高质量发展的重要推动因素。本文建立了数字经济发展水平评价指标体系，基于2015~2020年中国30个省、市、自治区的统计数据，从数字化基础建设和数字化应用水平对各地区的数字经济发展水平进行评价。本文用单位GDP能耗表征低碳节能发展，进一步研究数字经济发展水平对区域低碳节能发展的影响。实证结果表明：发展数字经济与区域单位GDP能耗降低有明显关联，在东、中、西部地区，每提升一单位数字经济发展水平，单位GDP能耗下降程度分别为0.31、0.27和0.16。
In the context of the “double carbon” target, the digital economy has become an important driving factor for high-quality economic development. This paper establishes an index system for evaluating the development level of digital economy, and evaluates the development level of digital economy of each region in terms of digital infrastructure and digital application level based on the statistics of 30 Chinese provinces, cities and autonomous regions between 2015 and 2020. This paper uses energy consumption per unit of GDP to characterize low-carbon and energy-saving development, and further investigates the impact of the level of digital economy development on regional low-carbon and energy-saving development. The empirical results show that there is a significant correlation between the development of digital economy and the reduction of regional energy consumption per unit of GDP. In the eastern, central and western regions, the energy consumption per unit of GDP decreases by 0.31, 0.27 and 0.16 for each unit of digital economy development, respectively.
