Chinese economic develops fast and have became the second economic entity all around the world. The development of economic pushes the popularize of mobile clients. Accordingly, whenever and wherever the consumers are, they can acquire and share information about productions directly, e-word-of-mouth (eWOM) becomes one of the important part of online marketing. Customers prefer to trust opinion leaders and real users’ feedback rather than the advertisements which are made by companies. The choice preference of information source accelerate the development of social media.
The Word of Mouth Marketing Association, have grown rapidly and have advocated for the burgeoning new industry. (Robert V. et al., 2010) Marketers and sociologists have recognized the importance of the phenomenon of word of mouth, for more than half a century, proposing, for example, that WOM affects the majority of all purchase decisions (Brooks 1957; Dichter 1966).They find that the “friend who recommends a tried and trusted product” rather than the “salesman who tries to get rid of merchandise” (Dichter 1966, p. 165). Marketing scholars has evolved from a transaction orientation to one based on relationships (Vargo and Lusch 2004) Consumers are regarded as active coproducers of value and meaning, whose WOM use of marketing communications can be idiosyncratic, creative, and even resistant (Brown, Kozinets, and Sherry 2003; Kozinets 2001; Muñiz and Schau 2005; Thompson and Sinha 2008) Therefore, when the behavior is on/off, impact measured as probability of purchase can differ substantially from impact measured as attitude change (Robert East 2015).
This study will select significant respondents from Chinese social media users as sample. The WOM communication is send information to marketers from the market-based message interaction community ,gathering consumers with same interests. In this study, not only structural equation modeling (SEM) will be used to test research model. But also using the fuzzy-set Qualitative Comparative Analysis (fsQCA) and SPSS, the first method attempts to find a new configuration to verify the finding and the SPSS can be used to make reliability analysis and validity analysis. WOM of the research model will also be tested by fsQCA and SPSS to obtain the conclusion about what extent do two communication ways influence consumers’ purchase preference.
We want to explore different results between opinion leaders and the real users in different communication ways. Based on the results we will give some implication to both marketing scholars and practitioners.
