PurposeThis article illustrates how, during the COVID-19 pandemic, emerging market exporting firms can adopt differentiation strategies using composition-based capabilities, which, in turn, will enable them to strengthen their images and market shares, i.e. their strategic marketing performance in advanced markets.Design/methodology/approachThis study is based on survey data obtained from 86 Pakistani firms exporting to advanced economies.FindingsThe study found that compositional collaboration capabilities positively influence the differentiation strategies and strategic marketing performance of emerging market exporting firms conducting business in advanced host markets. Furthermore, the findings indicate that differentiation strategies mediate the influence of compositional collaboration capabilities on the strategic marketing performance of these firms.Originality/valueBy taking a new compositional based theoretical perspective, this study examined the underexplored phenomenon of how emerging market firms can differentiate their offerings in advanced export markets in order to achieve a better strategic performance during external shocks such as the COVID-19 pandemic. Given that export growth is a strategic priority for many emerging markets, including Pakistan, due to their substantial trade deficits, this study provides important contributions from both the theoretical and practical perspectives.
