This study draws on the exchange relationships literature to create a model of what motivates corporate customers to continue their relationships with their primary banking services providers. The study reports the results of a questionnaire survey administered to financial managers (N = 259) in China. Results provide evidence for the existence of a number of antecedents and consequences of commitment in bank–corporate relationships. Notably, service quality is found to be a significant antecedent of affective commitment, which in turn leads to cooperation and continuance intentions. Implications for bank management are discussed along with avenues for future research.
