“…Based on an analysis of existing studies, we believe that spatial spillover has not yet received sufficient attention from researchers, although the existence of spatial spillover has been identified in studies of overall energy or conventional energy [ 18 , 19 ]. Moreover, we find that, except for a very few scholars such as Magnani et al (2013), most scholars (Inglesi-Lotz et al, 2015; Bao et al, 2019; Bai et al, 2020; Mohsin et al, 2021; Gyimah et al, 2021; Pereira et al, 2022; Li et al, 2022; Hou et al, 2022) use clean energy consumption as the core explanatory variable in their regression models when studying the relationship between CED and EG, rather than CEP.…”
