PurposeThe purpose of this study is to analyse factors influencing subscribers' usage of 3G mobile services in Taiwan.Design/methodology/approachThe research model, based on a technology acceptance model (TAM) and added perceived enjoyment, was tested by means of a two‐stage structure equation modelling approach. Data were collected from 532 respondents via a web questionnaire survey.FindingsThe findings indicate that perceived usefulness, perceived ease of use and perceived enjoyment are positively related to attitude, and perceived enjoyment has a positive influence on perceived usefulness.Practical implicationsThe findings suggest users of 3G mobile services need to be provided with more diverse and entertaining ways of communicating, which are at the same time easily accessible and convenient to use.Originality/valueA new correlation from perceived enjoyment to perceived usefulness was found to have a significant effect. This finding indicates enjoyment as a key factor influences customers' adoption of 3G services.

This explanatory research explores the relationship among environmental uncertainty, knowledge transfers mechanisms, dynamic capability, and competitive advantage. A total of 235 project managers employed by energy companies in Thailand were invited to participate in the study. The findings indicated that (a) through knowledge transfer mechanisms, project teams could develop an energy enterprises core competence and build its competitive advantage, (b) the relationship between environmental uncertainty and knowledge transfer mechanisms is negative, and (c) dynamic capability and competitive advantage have a positive relationship. The limitations of the study regarding generalization, and recommendations for future research to replicate the study in other countries, are also included.
