PurposeThe recent rise of economic nationalism intensifies consumers' patriotic attitudes toward goods or services and thus encourages enterprises to build patriotic brand images. Nevertheless, few studies have discussed how a patriotic brand image is developed. The purpose of this study aims to fill the gap by examining whether and how a positive corporate image helps a domestic brand establish a patriotic brand image and in turn enhances consumers' purchase intentions in relation to domestic brand products.Design/methodology/approachA research model identifying the antecedents of patriotic brand image (the components of corporate image) is proposed and empirically tested using structural equations with a questionnaire investigating Taiwanese college students' attitudes toward Taiwanese smartphone brands. Three competing models are also proposed and tested to confirm the appropriateness of the research model.FindingsIn addition to the widely recognized impact of perceived quality on purchase intentions, patriotic brand image is found to be effective in enhancing local consumers' intentions to purchase domestic brand products. To shape a patriotic brand image, perceived quality, perceived corporate ability and perceived corporate integrity are the direct approaches, while perceived corporate social responsibility works through perceived corporate integrity, and perceived employer brand enhances only perceived corporate social responsibility.Research limitations/implicationsPotential sampling (college students) and subject (smartphones) biases may limit the generalizability of the presented findingsPractical implicationsWhile patriotic appeals have long been used in marketing communication, they are also likely to precipitate negative brand associations (e.g. nationalism), offending consumers in other countries. By contrast, the development of a positive corporate image serves as an implicit and neutral approach to building a patriotic brand image and can help domestic brands attract local consumers with less harm to foreign markets.Originality/valueThis study is one of notably few studies discussing patriotic brand image and its impacts on purchase intentions. This study also identifies the antecedents of patriotic brand image and how each of them affects patriotic brand image. The findings can help guide domestic brands in building a patriotic brand image.
