PurposeThis paper examines the direct relationship between perceived corporate citizenship (CC) and purchase intention. This study also tests the mediating role of brand trust (BT), consumer–brand identification (CBI) and the moderating effect of personal norms and fear to coronavirus disease 2019 (COVID-19) by contributing social exchange theory (SET), brand relationship theory, social cognitive theory (SCT) and fear appeal theory.Design/methodology/approachQuantitative research was carried out by means of a survey with a sample of 411 regular consumers who work for national retail brands, where the unit of analysis was an individual. The study analysed the data to test the research hypotheses using SPSS and SMART partial least squares (PLS).FindingsThis study found a significant positive impact of perceived CC on purchase intention (direct path), and furthermore, a partial mediation was shown for the indirect approach. In addition, personal norms and fear to COVID-19 have a significant impact on the relationships between perceived CC on purchase intention, BT on purchase intention and CBI on purchase intention.Practical implicationsThis study provides useful insights for managers to implement CC strategies to enhance consumer purchase intention and brand relationship in the retail sector within the COVID-19 pandemic.Originality/valueThe current study is perhaps the first to investigate the impact of perceived CC on purchase intention across BT, CBI, personal norms and fear to COVID-19 in the retail industry, period of COVID-19 pandemic. The study also makes some significant theoretical contributions and previously did not shed light on customer behaviour in this context.
