In recent decades, social media has fundamentally changed how communication takes place in business. It has contributed to the evolution of the Internet from a broadcasting medium to a participatory and interactive platform which allows users to generate and share information and become part of the media. For instance, social media has enabled the creation and exchange of electronic word-ofmouth (eWOM). We have witnessed the popularity of eWOM in travel and tourism industry. 

EWOM behaviour among individuals and the impact of eWOM on organizations have become important research focuses in eWOM research. However, the extant research has ignored the important function of social media platforms as both hedonic and social-oriented information systems (IS) for users, and few researchers have tried to explain eWOM use from the social, hedonic, and technology perspectives. eWOM application from the organizational perspective has also attracted the attention of researchers. Most prior studies in this field have focused primarily on the impact of eWOM on business performance and organizations’ eWOM strategy. However, the understanding of how social media platforms can be used to co-create value with customers and how eWOM can help organizations to engage customers is still fragmented. What is more, the understanding of the interplay between an organization’s activity and social media technology remains obscure. 

The objective of this study is threefold: 1) to explore eWOM use and generation behaviours among individuals by taking eWOM content, as well as the social media platform—that is, the channel of eWOM generation and use—into consideration; 2) to explore the value creation of social media and eWOM in organizations; and 3) to examine how social media and eWOM connect individuals and organizations and uncover the myth of how eWOM benefits both individuals and travel organizations. A combination of quantitative survey research and qualitative case study is used in this study. In particular, quantitative survey research method was used to explore the eWOM use among individual user’s to solve the research questions regarding the determinants of travellers’ eWOM use and generation behaviours. Qualitative case study method was used to solve the questions regarding how can tourism organizations use social media to co-create value with customers and to engage with customers via eWOM communication. This research includes empirical data collected from individual tourists in China and tourism organizations from both China and Finland. 

This study contributes to the understanding of eWOM in tourism context. Specifically, it contributes to the understanding of customers’ eWOM behavior by taking the social and hedonic functions into consideration, and sheds light on the understanding of eWOM application in organizations. This study also integrates eWOM research from both individual and organization perspectives and helps to explain the eWOM interplay between them. From practical view, the results of this study have important implications for tourism e-service practitioners in their understanding of customers’ decision making process, and the strategy to facilitate customers’ propensity of eWOM generation behavior. It also helps eWOM website designers to make successful eWOM websites. The findings also shed lights on e-service providers on how to co-create value with customers via social media platform and how to engage customer via eWOM communication.
