An increasing number of lodging businesses utilize online third-party intermediaries (OTPIs) for distribution services on the internet. The purpose of the study was to investigate the decision-making processes of lodging firms in the adoption of OTPIs. The study developed and tested a conceptual model by strategically combining a technology–organization–environment framework (TOE) and an expectation–confirmation model (ECM). The results showed that, with regard to TOE, technology and organization have significant impacts on confirmation in ECM. Furthermore, the environment aspect of TOE significantly influences satisfaction in ECM, and both confirmation and satisfaction are antecedents of continuance intention. The study contributes to the knowledge body of TOE and ECM, and provides industry practitioners with strategies for the communications and decision-making processes of lodging businesses and OTPIs.
