AbstractPurpose -The purpose of this paper is to investigate the factors that underpin brand switching of medical imaging products by mass-market users. Most of the literature on brand switching is focused on competitive market products, for which switching costs are manageable. However, little consideration is given to brand switching of high-technology capital products. Design/methodology/approach -The conceptual model is developed based on the existing literature on B2B brand switching. An online survey was developed and distributed to decision makers involved in purchasing medical imaging technology. Findings -The results confirm the expectation that product features is the most influential factor underpinning brand switching. Product features are critical for medical organizations who want to maintain their competitive advantage. The findings suggest that the set of factors that influence the decision to switch is unique for users of different market segments in the same industry (e.g. lead users and mass-market users). This difference stems from technology utilization of each market segment. Research limitations/implications -In high-technology markets, managers should develop a reliable strategy to evaluate the antecedents behind brand switching that are specific to their industry. Knowledge of the major factors that cause users to switch is essential to allow firms to determine the strategy needed to prevent the erosion of their market share. Originality/value -Although the literature reports considerable research on brand switching, this study is a first-of-its-kind in that it demonstrates that the factors underpinning brand switching vary within the same industry, based on the characteristics of each market segment. This paper develops new knowledge on the factors that influence the decision of users of high-technology capital products to switch between brands to renew or improve their internal capabilities.
