Proceedings of 7th Asia-Pacific Business Research Conference 25 - 26 August 2014, Bayview Hotel, Singapore ISBN: 978-1-922069-58-0 A Study on the Social Influence Process of a Virtual Community Cedric Hsi-Jui Wu* and Hsiao-Chun Liao** In recent years, consumer behavior and business model change quickly because of the rapid development of Internet and information technology. In addition, previous studies have suggested that one of the success factors of e-commerce is using virtual communities as a marketing channel, such as facebook, twitter etc. This is because those virtual community members frequently browse within the community, updating their personal information, sharing knowledge, and making them into a necessary part of their lives. Therefore, virtual communities have established in large quantities and provide a variety of diversified services. Therefore, the commercialization process of the virtual community is like a kind of business model. How to attract online users to purchase a product or service of the virtual community is the most important issue. This study explores the conception of social identity and social influence on purchase intention to use a virtual community service. Use of a virtual community service can be regarded as consumer behavior by social factors. This study relies on the link between social identity, social influence and purchase intention in the social identity literatures. This study also proposes a concept model, and expects to contribute to the literature on the social influence process. Key Words: Virtual community, Social identity, Social Influence, Purchase Intention. *Professor, Cedric Hsi-Jui Wu, Dept. of Business Administration, National Dong Hwa University, Taiwan.
