摘要：Mobile payment is becoming an evitable trend in the globe and is well expanding rapidly into
emerging countries. Many research models are developed and confirmed that behavior intention is
an important fact which decides the level of using mobile payment among users. The existing
research models have made empirical evidences confirming behavior intention depended on performance
and effort expectancy. This research expands previous empirical evidence by involving
perceived transaction speed as an important explanatory variable to both performance expectancy
and effort expectancy and also captures how behavior intention is influenced by performance expectancy
and effort expectancy among Cambodian users. A total of 200 questionnaires were collected,
analyzed and summarized for this study. Result reveals that performance expectancy and
effort expectancy affect positively and significantly on behavior intention. Perceived transaction
speed has a positive and significant relationship with effort expectancy but Perceived transaction
does not have any positive and significant relationship with performance expectancy. Result from
this study also concludes the role of perceived transaction speed which is affecting intention to use
mobile payment among users. However, there are some limitations to be addressed for the future
researches; this research may include larger samples to find out the clear effect on behavior intention
of the end-users.
