Research on the Coupling Coordination Degree between Urban Carbon Offsetting Capacity and Urbanization:A Case Study of Dalian City
Taking the data in Dalian from 2005 to 2021 as the research object,the urban carbon sink and energy carbon emissions of Dalian are calculated by adjusting the energy carbon emission factor,and a coupling coordination degree model between urban carbon offsetting capacity and urbanization is constructed.The Granger test and Stata causality analysis are used for verification,and the results show that the carbon sink and energy carbon emissions in Dalian City have been increasing year by year,but the rate of increase in carbon sink is far behind that of energy carbon emissions,resulting in a relatively low carbon offsetting capacity in the city.Dalian's carbon offsetting capacity shows a W-shaped trend,and the coupling coordination degree between the city's carbon offsetting capacity and various urbanization indicators is relatively low,basically maintaining a low level of coupling and imbalance;except for spatial urbanization,the coupling coordination degree between other urbanization indicators and carbon offsetting capacity is on the rise.Stata causality test shows that there is a Granger causality relationship between urbanization and carbon offsetting capacity in Dalian City.
