Analysis on Influencing Factors Decomposition and Decoupling Effect of Power Carbon Emissions in Yangtze River Economic Belt

The power industry is one of the main industries energy consumption and carbon emissions in Yangtze River Economic Belt, order to accelerate development green low-carbon power. This paper takes Belt upper, middle lower reaches from 2000 2020 as research object. Based on four absolute factors economy, consumption, population output, generalized divisia index method (GDIM) constructed. Combining decoupling model with GDIM method, a effort constructed based DPSIR framework incorporate electricity output economic scale into drivers. findings are follows: provide contribution area emissions, high value tends migrate eastward. Economy, leading increase reaches, while intensity key curbing emissions. Among them, largest positive driving factor negative upper reaches. total effect increased most achieved between 2014 2020. From 2016 2020, fluctuates within certain range, has entered pressure period.
