Abstract
The purpose of the present study is to examine the relationships among motives, usages, and gratifications of Plurk users. A total of 205 samples were collected through survey. Data were analyzed via Pearson correlation, structural equation modeling and hierarchical regression to test the proposed model. The results showed that (1) User motives have a positively impact on usages: performance expectation, effort expectation and facilitating condition have positively impacts on human-message interaction; and performance expectation and facilitating condition have positively impacts on human-human interaction; (2) Usages have a positively impact on user gratification: human-human interaction has a positively impact on information obtained, mood sharing, entertainment, and relationship maintenance; and human-message interaction has a positively impact on relationship maintenance. Finally, theoretical and practical implications and suggestions for future studies are also discussed.
