Differentiation research of CO2 emissions from energy consumption and their influencing mechanism on the industrial enterprises above designated size in Chinese industrial cities: based on geographical detector method

Industry is one of the three fields of CO2 emissions in Chinese cities. By measurement and analysis of data, the inter-city differentiation of CO2 emissions from energy consumption and their influencing mechanism of the industrial enterprises above designated size (IEDS) in 59 non-resources-based industrial cities at prefecture level and above in different regions and types is obvious. In terms of CO2 emissions from energy consumption per unit of employment, central and western industrial cities are above the average level of all industrial cities and cities of chemical and petrochemical, metallurgy and building materials see the same pattern; in terms of CO2 emissions from energy consumption per unit of output, northeast industrial cities are all above the average level of all industrial cities, and it is the same for metallurgy and building materials industrial cities, chemical and petrochemical industrial cities. With geographical detector method, the size of each influencing factors of CO2 emissions from energy consumption of the IEDS in industrial cities is probed. The results show that energy consumption structure and economic scale are the main influencing factors of CO2 emissions from energy consumption of the IEDS in industrial cities; the influencing factors of CO2 emissions in industrial cities from different regions and types are significantly spatially varying, and one factor also has diverse influence on CO2 emissions in cities from different regions and types. Therefore, different countermeasures and actions to achieve low carbon transformation should be adopted according to the region and type of each industrial city.
