“…The CO 2 emission inventory provides a quantitative basis for CO 2 emission mitigation policies formulation and effectiveness evaluation of relevant policies (Ramaswami et al, 2008;Kennedy et al, 2010;Guan et al, 2018;Shan et al, 2018b;Chen et al, 2020;Murakami et al, 2020). Many studies have conducted decoupling analysis of CO 2 emissions from economic growth at the national and provincial levels, discussed the decoupling degrees, its drivers, and low-carbon development pathways (Muller, 2014;Ponce de Leon Barido and Marshall, 2014;Chen et al, 2018;Engo, 2019;Lu et al, 2019;Shuai et al, 2019;Li and Jiang, 2020;Raza and Lin, 2020). For example, based on the Kaya identity, Deutch (2017) analyzed the decoupling between CO 2 emissions and economic growth of the USA, China, and the World, and found that the degree of decoupling depended entirely on the reduction of energy and carbon intensity.…”
