Abstract
This study provides insight into how social relationship factors influence on electronic Word-of-Mouth (EWOM)

more time on social networking sites, we investigate these determinants of EWOM behaviors such as social

positively significant influence on EWOM behaviors, and there are different about some factors between Taiwan
and Vietnam. Taiwan consumers are found to have more bonding social capital, trust and normative influence
than Vietnam counterparts do
