“…In this study, followingChen et al (2021), we use the term "vendor" to refer to a potential supplier, and we use the term "supplier" to refer to an actual supplier selected by a customer firm, while the term "non-supplier vendor" is used to refer to a potential supplier that is not selected as an actual supplier.2It is well documented that macroeconomic conditions(Bansal et al, 2015;Ramya & Baral, 2021), industry and regional factors(Flammer, 2015;Lei & Yu, 2024), firm attributes(Drempetic et al, 2020;Yang & Han, 2023), and executive characteristics(Chin et al, 2013;Zhang et al, 2020) can affect CSR engagement and corporate sustainability performance.3The framework of SSCM has been extensively discussed in prior studies(Ahi & Searcy, 2013;Carter & Rogers, 2008;Pagell & Wu, 2009;Seuring & Müller, 2008), andHassini et al (2012) defined SSCM as "the management of supply chain operations, resources, information, and funds in order to maximize the supply chain profitability while at the same time minimizing the environmental impacts and maximizing the social well-being".…”
