Abstract

Considering digital economy (DE) as a driving force for high-quality development, it is important to clarify its impact on industrial carbon emission efficiency (ICEE). The study investigates the impact mechanism, nonlinear effect, spatial spillover effect and spatial threshold effect of the DE on ICEE by using panel data of 284 cities in China from 2011 to 2021. The results show that: (1) DE exhibits a nonlinear impact on ICEE. When DE exceeds 0.3414, the impact turns from negative to positive. (2) There exists a significant spatial threshold effect of DE on ICEE. (3) DE affects ICEE through scale effect, technological effect and structural effect. There are also threshold effects on the mechanisms by which DE affects ICEE. Additionally, under different development levels of the three mechanisms, the impact of DE on ICEE also exhibits variations. This study provides inspiration for fully unleashing the carbon reduction dividend of DE and forming a joint force of urban industrial emission reduction.

数字经济对工业碳排放效率的影响研究——基于空间阈值模型的分析

考虑到数字经济作为高质量发展的动力，明确其对工业碳排放效率（ICEE）的影响至关重要。利用2011 - 2021年中国284个城市的面板数据，研究了经济发展对城市综合消费水平的影响机制、非线性效应、空间溢出效应和空间阈值效应。结果表明：(1)DE对ICEE具有非线性影响。当DE超过0.3414时，影响由负向正。(2) DE对ICEE存在显著的空间阈值效应。(3) DE通过规模效应、技术效应和结构效应影响ICEE。DE影响ICEE的机制也存在阈值效应。此外，在三种机制的不同发展水平下，DE对ICEE的影响也表现出差异。本研究为充分释放DE的碳减排红利，形成城市工业减排合力提供了启示。

期刊介绍： The Journal of Cleaner Production is an international, transdisciplinary journal that addresses and discusses theoretical and practical Cleaner Production, Environmental, and Sustainability issues. It aims to help societies become more sustainable by focusing on the concept of 'Cleaner Production', which aims at preventing waste production and increasing efficiencies in energy, water, resources, and human capital use. The journal serves as a platform for corporations, governments, education institutions, regions, and societies to engage in discussions and research related to Cleaner Production, environmental, and sustainability practices.
