In highly competitive environment nowadays, E-commerce can be considered as an important source of competitive advantage for most of enterprises, especially small and medium enterprises (SMEs). Before, the researches focused mainly on the adoption of E-commerce in developed countries. However, today, with the steady development of economy, developing countries (including Vietnam) have gained more and more attentions of researchers. Thus, the studies in this field are rising.
The concept “E-commerce” appeared when business organizations began to realize the important role of Internet as a means for conducting business. According to Chaudhury & Kuiboer (2002), E-commerce has been significantly contributed in reducing in costs of doing business, improving product/service quality, attracting new customers and suppliers, and developing new ways for product distribution. It brings benefits not only to large enterprises but also SMEs.
Over the last few years, after Vietnam implemented Reform (Doi Moi) policy and opened its market, a number of Vietnamese SMEs have implemented and gained benefits from it.
The purpose of this study is to examine and to understand more clearly the  influence of relevant factors on the acceptance of SMEs’ employees, who directly use E-commerce in their enterprises. A research framework was developed and seven hypotheses were formulated to test the relationships. Developing and testing hypotheses by using survey data from 340 employees of SMEs in Nam Dinh province, in Viet Nam. This research employed SPSS 13.0 to analyze the collected data to test the relationships among factors and all items require five-point Likert-scale.
Support was found for all of the seven hypotheses formulated. The results indicate the positive relationships among Information quality, System quality, Intention to Use, User Satisfaction and E-commerce Adoption.
