“…Another area of study is related to eco-innovation drivers, for which different authors have advanced knowledge significantly in the last decade. Among the identified variables that favor and guide eco-innovation are: firms' technological trajectory (Sáez-Martínez, Díaz-García, & Gonzalez-Moreno, 2016), collaboration with research institutions (Triguero, Moreno-Mondéjar, & Davia, 2013), demand factors (Cai & Zhou, 2014), and environmental regulations and firms' internal organizational capabilities (Bossle, de Barcellos, Vieira, & Sauvée, 2016;Kesidou & Demirel, 2012). Smith and Crotty (2008) named environmental regulations as driving eco-innovation in the UK automobile sector, while regulatory and internal pressures have also been identified by Zhu, Sarkis, and Lai (2007) and Lin et al (2013) as causative variables for greening the automobile supply chain.…”
