Study on the mechanism of the influence of structural change on China's carbon emissions

Revealing the influential mechanism of important factors on carbon emissions of economy or industry is the premise of formulating effective emission reduction policies and implementing positive emission reduction measures, and also a hot research topic in academic circles. This dissertation constructs a theoretical model for analysing the mechanism of carbon emission impacts considering structural factors. The impacts of changes in demand and supply linkages in the production links of the economic subsystem are incorporated into the decomposition model, and key industries and factors affecting carbon emissions at the production and demand sides are identified and quantitatively analysed from the perspective of the subsystem. The main conclusions are as follows: The change in energy use structure and production efficiency is the main reason for the downward trend of carbon emissions. The effect of the change of demand structure on emission reduction is far less than that of the change of production structure factors, and the change of demand structure is not always advantageous to emission reduction during the research period. In the short term, promoting the optimization of production and demand structure is still an important effort to promote emission reduction. In the long run, the emission reduction effect of energy structure optimization is the most significant. (paper)
