“…Researchers applying the STIRPAT frame to carbon emissions or energy use typically include data on population, income, urbanization level, urban density, and age compositions in their analyses, summarized in the appendix A1 (Boyko and Cooper, 2011;Fan et al, 2006;Hossain, 2011;Liddle, 2004;Liddle and Lung, 2010;Martínez-Zarzoso et al, 2007;Martínez-Zarzoso and Maruotti, 2011;Menz and Welsch, 2012;Norman et al, 2006;Perkins et al, 2009;Poumanyvong and Kaneko, 2010;Poumanyvonga et al, 2012;Yang et al, 2015;Zhu and Peng, 2012). The common feature in these studies is the lack of information on the urban form which may be ascribed to the deficiency of appropriate measures of urban area level spatial structure (Lee and Lee, 2014) as well as the limited variables in the STIRPAT framework.…”
