Decoupling index measurement and influencing factors of carbon emission in the three northeastern provinces of China
Based on the carbon emissions generated by energy consumption in the three northeast provinces of China from 1997 to 2016,the decoupling relationship between carbon emissions and economic growth was explored by Tapio decoupling model,and the influencing factors of carbon emissions and their interaction were studied in depth by using element decomposition,cointegration test and impulse response analysis.The results show that:l)In the study period,the decoupling state of each region changed greatly.2)GDP has the most obvious promoting effect on the increase of carbon emissions,followed by the effect of oil consumption and demographic factor;the interaction effect of multiple factors is more obvious than that of single factor.3)GDP and carbon emissions are stable at different lag orders,and there is a correlation between them for long-term cointegration.When GDP has an impact on carbon emissions,the carbon emissions of Heilongjiang Province first increase and then decrease;when carbon emissions have an impact on GDP,the changes in GDP of Jilin Province and Liaoning Province are relatively stable.The conclusions of this study are conducive to the understanding of various influencing factors affecting carbon emissions and provide scientific support for the government to make reasonable decisions and policies.
