The impact of artificial intelligence on urban energy consumption
基于中国281个地级市2008-2021年面板数据，采用双向固定效应模型发现人工智能通过提升绿色全要素能源效率来优化城市能源消耗，效果因城市地理位置和属性而异。
Managing urban energy use is a critical challenge for cities striving to achieve green and sustainable development, and also a vital focal point for propelling the synergistic growth between urban economic and environmental systems. Leveraging panel data from 281 prefecture-level cities in China spanning 2008 to 2021, this study adopts a two-way fixed effects (TWFE) model to assess the influence of artificial intelligence (AI) on urban energy consumption (UEC) optimisation. The results reveal that AI exerts a significant influence on the optimisation of UEC, and this impact stays robust following a series of robustness tests. Heterogeneity analysis, which accounts for geographical location and specific urban attributes, reveals substantial differences in the potential and actual effects of AI in optimising energy consumption across different cities. For cities in China's northeast and central regions, non-resource-based cities and low-carbon pilot cities, AI implementation has produced impressive results in the optimisation of energy consumption. However, for cities in eastern and western China, as well as resource-based cities and non-low-carbon pilot cities, AI's role in energy consumption optimisation has not been fully validated. The mediating effect test confirms that AI optimises UEC by enhancing green total factor energy efficiency. The findings have policy implications for the rational application and widespread deployment of AI in cities. The results serve as a basis for evidence-backed choices when developing precise energy policies, supporting the ongoing refinement of UEC and advancing the objective of sustainable urban development.
