How Blockchain-Enabled Drivers Stimulate Consumers’ Organic Food Purchase Intention: An Integrated Framework of Information Systems Success Model Within Stimulus-Organism-Response Theory in the Context of Vietnam

Abstract

Integrating the Information System Success (ISS) model with the Stimulus-Organism-Response (SOR) paradigm, this study aims to explore how blockchain-enabled stimuli (blockchain-enabled traceability and blockchain-enabled transparency) affect ISS-related organisms (perceived information quality and perceived system quality), which individually, congruently, and incongruently trigger consumers’ behavioral responses (organic food purchase intentions). Using a purposive sampling of 5326 Vietnamese consumers, multiple linear regression and polynomial regression with response surface analysis are employed to examine the hypothesized model. The research indicates that both blockchain-enabled traceability and blockchain-enabled transparency significantly and positively affect perceived information quality and perceived system quality, which both significantly mediate the impacts of blockchain-enabled traceability and blockchain-enabled transparency on organic food purchase intention. The research also finds that higher congruence between perceived information quality and perceived system quality leads to increased organic food purchase intention, while greater disparity between perceived information quality and perceived system quality results in lower organic food purchase intention. This study contributes to the extant literature by integrating the ISS model with the SOR model to provide a comprehensive framework for understanding how blockchain technology affects consumer behavior in the organic food market. It also highlights the crucial role of both information and system quality in leveraging blockchain technology to enhance consumer trust and purchase intentions.
