【 摘 要 】

After calculating and analysing the carbon emissions for industrial energy consumption in Dalian during 2007 to 2014, the LMDI model is built to decompose the influencing factors on carbon emissions from the perspectives of energy structure, energy intensity, industrial structure and output scale. As many as 17 types of energy are involved in the calculation of emissions, and based on the specific industrial structure of Dalian, the analysis for the influence on carbon emissions from industrial structure is made from the perspective of light and heavy industry. The result shows, output scale effect is a major contributor for the growth of the carbon emissions for industrial energy consumption in Dalian, while energy intensity effect is the principal inhibitor. Energy structure and industrial structure influence relatively weakly on the energy-consumption emissions, which indicates that the emission reduction potentials from these two perspectives are still not achieved.
