摘要: Abstract The International Energy Agency (IEA) pointed out that thermal electricity generation was the largest contributor to CO2 emissions in 2018, particularly China. Inequality and spatial decomposition analyses have been extensively applied monitor climate change. However, there no studies focusing on inequality of or aggregate carbon intensity (ACI) sector. Furthermore, analysis not combined analyze ACI This study adopts Theil index intraregional interregional provincial China’s In addition, nested approach is proposed isolate factors behind variation at regional levels. most grids declined substantially during 2000–2016. By 2016, half provinces had achieved 2020 reduction target 865 gCO2/kWh ahead schedule. Decomposition based demonstrated major factor causing overall ACI, especially within North South regions. indicates energy significant decrease followed by structure. emission coefficient exerted limited impact across all six Besides, Northwest rose rankings intensity, structure, 2000–2016, whereas Northeast saw opposite pattern. Policy implications empirical research are provided further govern curb emissions.
