Abstract
PurposeThis study aims to explore the collaborative value creation process in the context of regional public brands within the specialty agricultural products domain. It examines the role of cluster social capital in facilitating stakeholder interactions and cooperation, thereby enhancing the value of these brands.Design/methodology/approachThe study adopts a value co-creation theoretical framework to construct a relational model that links cluster social capital, brand interaction, stakeholder perceived value, and the value of regional public brands. An empirical analysis is conducted using a sample of 404 valid responses to test this model and assess the influence of cluster social capital on brand value co-creation.FindingsThe findings reveal that cluster social capital significantly impacts stakeholder participation in value co-creation activities, thereby playing a crucial role in enhancing the value of regional public brands. The study also finds that brand interactions significantly affect stakeholder perceived value and the overall brand value, with perceived value acting as a partial mediator in these relationships.Originality/valueThis research contributes to the understanding of value co-creation in regional public brands, particularly in the agricultural sector. It provides new insights into how cluster social capital influences the value creation process, offering valuable implications for policymakers and practitioners working to develop and promote regional public brands in the specialty agricultural products market.
