Empirical Study on the Impact of Urbanization and Carbon Emissions under the Dual-Carbon Framework Based on Coupling and Coordination

Abstract

At present, there are two modes between urbanization and carbon emissions, namely mechanisms of increasing carbon and mechanisms of decreasing carbon. This paper uses the definition of environmental coupling and coordination to study the effect of the mechanism of reducing carbon emissions in urban construction and empirically analyzes its relationship with carbon emissions under the background of dual-carbon. In addition, through the selection of the relevant index system and the objective design of the parameters in the model of the traditional coupling coordination degree, the temporal and spatial characteristics of the relationship between the two are analyzed. The coupling coordination degree of urbanization construction and the improvement of carbon emission systems in all provinces is generally on the rise. This is specifically reflected in the range of the coupling coordination degree in 2020 (0.1621~0.7334), which is first enhanced and then weakened compared with the previous data (0.1282~0.4868), indicating that the positive promotion effect of regional urban development and cooperation regarding the construction of low-carbon environments is declining. The maximum value of regional spatial autocorrelation reached 0.24, and the regulatory interaction coefficients of carbon reduction technology and regional cooperation were 0.1538 and 0.4807, respectively. This indicated a positive role in promoting the development of regional urbanization, which can accelerate the process of carbon reduction. However, at present, the positive effect of urbanization construction cooperation or carbon emission reduction cooperation is weakening, and the characteristics of spatial imbalance are relatively obvious. Therefore, in the future, administrators should speed up the adjustment of the spatial coordination of urban development and the formulation of relevant carbon emission reduction policies and measures and improve the spatial relevance of the coupling coordination degree so as to achieve the efficient development of a low-carbon economy in the context of dual-carbon.
