城市活力对城市碳排放的作用机制与空间效应
Mechanism and spatial effects of urban vitality on urban carbon emissions:An empirical analysis based on the Spatial Durbin Model
摘要
Abstract
Balancing the enhancement of urban vitality with carbon mitigation is a core challenge for urban sustainable transition.Addressing the ambiguity of spatial interaction mechanisms between these two factors at the micro-scale,this study constructs a six-dimensional vitality framework by integrating deep learning and multi-source data.Based on a 1 km grid of Yantai City and high-resolution Open-source Data Inventory for Anthropogenic CO2(ODIAC)data,the Spatial Durbin Model(SDM)is employed to analyze the driving mechanisms and spillover effects.The results indicate that:1)There is significant spatial coupling between urban vitality and carbon emissions,with carbon emissions exhibiting strong spatial dependence and positive interaction.2)The driving effects of different vitality dimensions show significant heterogeneity:spatial vitality significantly drives carbon emissions,whereas environmental vitality exerts a negative inhibitory effect.3)Key morphological factors reveal complex spatial externalities:plot ratio and maximum building height exacerbate local emissions,while average building height generates emission reduction benefits through technical spillovers.Integration presents a"local suppression-peripheral promotion"characteristic,confirming the existence of the carbon displacement effect.This study elucidates the effectiveness of micro-spatial governance and suggests achieving a synergistic co-existence of urban prosperity and low-carbon development through differentiated regulation and environmental design.关键词
