ABSTRACT: Firstly, the decoupling effect of national per capita GDP and carbon
emissions was analyzed based on Tapio decoupling model. Secondly, based on the provincial
panel data, the spatial Dubin model was established to conduct empirical
research on the impact of regional economic development on carbon emissions,
aiming to clarify the influencing factors and temporal and spatial
characteristics of Carbon emissions in China, and provide theoretical basis and
reference for the realization of “double carbon” target. Finally, the following
conclusions were drawn: 1) The decoupling state of national per capita GDP and
carbon emissions is mainly weak decoupling, and the decoupling is ideal, at the
same time, the emergence of strong decoupling shows that economic development
and carbon emission reduction can coexist. 2) The carbon emissions of provinces
(cities, autonomous regions) have spatial autocorrelation; Per capita GDP has a
significant impact on carbon emissions, and its direct and indirect effects
show inverted N-shaped and N-shaped curves respectively. 3) Both FDI and
R&D drive carbon emissions negatively, while urbanization and electricity
consumption drive carbon emissions positively, with the spatial spillover
effects of FDI and urbanization being statistically insignificant. In addition,
the direct and indirect effects of industrial structure and population density
are opposite. Based on the above conclusions, it is recommended that all
regions should strengthen joint prevention and control in the process of carbon
emission reduction, promote close cooperation in regional energy conservation
and emission reduction, develop a low-carbon economy, and take multiple
measures to help achieve the “double carbon” target successfully.
