What makes the corporate social responsibility impact on Customer–Company identification stronger? A meta-analysis

Customer–company identification (CCI) has been highlighted as an important mechanism that explains the relationship between corporate social responsibility (CSR) and customer outcomes such as customer loyalty and word-of-mouth (WOM). However, findings on when and how this mechanism works are mixed. To uncover the viability and strength of CSR's indirect effect on customer outcomes through CCI, we conduct a meta-analysis testing a moderated mediated framework. This analysis incorporates 237 independent effect sizes from 58,766 individuals and 86 papers to examine the indirect effect of CSR on customer loyalty and WOM through CCI, while simultaneously testing a range of substantive and control moderators. The results reveal that 1) CSR has a main effect on CCI, 2) CCI mediates the effect of CSR on customer loyalty and WOM, and 3) there are significant theoretical moderators that amplify and reduce CSR's relationship with CCI. The paper's year of publication and industry controversy (versus non-controversy) mitigate the relationship between CSR and CCI, while collectivism and a holistic focus augment it.
