Abstract
An empirical study was conducted in Hong Kong to investigate perceptions regarding the impact of company, subject, and system characteristics on trust factors affecting the adoption of internet-based interorganizational systems (IIOSs). Data were collected from 295 practitioners and analyzed using t-tests and one-way ANOVA. This study confirms that company size affects views regarding the importance of trust factors to the adoption of IIOSs. Thus, practitioners should focus on company size during the adoption of IIOSs.
