中国城市人口规模、产业集聚与碳排放

基于2009～2018年中国286个地级市面板数据,构建空间计量模型,从城市人口规模和产业集聚的综合视角探讨对于人均碳排放的影响机制.结果 显示:不同城市的人均CO2排放具有显著的空间溢出效应;城市人口规模和产业集聚与人均CO2排放之间均呈"倒U型"关系,且影响机制各不相同;产业集聚与城市人口规模在影响碳捧放上具有协同...

City population size,industrial agglomeration and CO2 emission in Chinese prefectures

Using the panel data of 286 cities in China during 2009~2018, a spatial econometric model was employed to explore the mechanism between CO₂ emissions and the size of city population and industrial agglomeration. The results revealed that CO₂ emissions per capita in different cities presented significant spatial spillover effects. Specifically, the impact of the city population size and industrial agglomeration on CO₂ emissions per capita presented an inverted U shape. CO₂ emissions were synergistically affected by city population size and industrial agglomeration. There were significant differences in CO₂ emissions and associated mechanism across different Chinese regions. A series of robustness tests confirmed our main findings. Therefore, for sustainable development policymaking, local governments should rationally formulate policies on energy conservation and emission reduction in accordance with the size of city population and industrial agglomeration.
