Decoupling effect of carbon emission and economic growth in China in recent ten years

Finding out about the decoupling of carbon emission and economic development can provide a favorable reference for China to realize the goal of "double carbon". On the basis of analyzing the characteristics of China's carbon emissions from 2011 to 2021, this article used the Tapio decoupling elasticity index to analyze the decoupling relationship between carbon emissions and economic growth. The results showed that: (1) In the past decade, China's carbon emissions showed a fluctuating upward trend, of which the average annual carbon emissions in Shandong Province reached 867.58 Mt, and the per capita carbon emissions in Inner Mongolia reached 0.27 Mt/ten thousand person; (2) The production and supply industry accounted for more than 50% of carbon emissions, which was the main social and economic sector of carbon emissions in China; (3) China's carbon emissions and economic growth showed a relatively stable decoupling state, and the decoupling of carbon emissions and economic growth was mainly caused by the decoupling of energy consumption and economy, but the decoupling elasticity of carbon emissions and energy consumption was higher than that of carbon emissions and GDP on the whole. It shows that China's coal-dominated energy consumption structure and carbon emission reduction technology level affect the efficiency and effect of carbon emission reduction to some extent.
