Abstract: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.
