This paper develops a general model of industrial brand value and relationship performance in business-to-business markets from the perspectives of consumer and industrial marketing literature. The structural equation model integrates the analysis of industrial brand value and relationship performance. The model describes the extent to which supplier–buyer transaction performance is influenced by the eight important factors: supplier competence, purchasing value, customer satisfaction, switching cost, brand trust and loyalty, relationship quality, commitment, and transactional performance. The general model is applied to organizational buyer groups of comprehensive industrial markets (Electronics, Chemicals, Equipment, etc). The analysis finds that supplier competence directly affects purchasing value and customer satisfaction, and via purchasing value and customer satisfaction, it indirectly affects commitment, switching cost, brand trust and loyalty. The managerial implications of the study results are also discussed.
