数字经济影响我国城市碳排放的空间差异分析
Analysis of the spatial differences in urban carbon emissions influenced by digital economy in China
摘要
Abstract
In the era of digital economy,China's"dual-carbon"strategy drives the transformation of its economy toward high-quality development.Therefore,this study investigates the spatiotemporal character-istics and spatial effects of carbon emissions across 285 cities.The results indicate that:(1)Both urban car-bon emissions and digital economy development exhibit spatial correlations;(2)A"club convergence"phe-nomenon exists among regions at different development tiers,with the digital economy demonstrating a pronounced"Matthew effect"in interregional development trends,while urban carbon emissions display a downward transfer pattern;(3)Spatial econometric models reveal that the digital economy exerts signifi-cant spatial spillover effects on carbon emissions.Industrial structure shows notable short-term spillover effects,whereas research investment demonstrates stronger direct effects in the long term.关键词
