ABSTRACT The growth of the social platform has led to a rapid increase in sustainable value cocreation activities with customers in order to know what a customer wants. In this study, we have studied about co-creation experience in social platform service. Previous prior studies have systematically classify co-creation between customer and enterprise as co-product and value-in-use, Conceptual factors. The co-creation and value-in-use factors theoretically derived from previous researches attempt to investigate the relationship between value co-creation experience and online service quality. We also tried to investigate the relationship between value co-creation experience and online service quality, customer equity, and online word of mouth. To do this, social platform services are divided into open sns and closed sns. Open SNS was targeted to Facebook, Twitter, and Pintrest users. Closed sns were targeted to Instagram, Cyworld, Band, and KakaoTalk users. In this study, it was confirmed that the relationship between online service quality, customer equity, and online word of mouth is significant through value co - creation experience. In the future, companies that design social platforms will be asked to do what they should do to co-create with customers, and provide suggestions for how to operate the platform in order to continuously activate value co-creative experiences.

Introduction Why should we study marketing management processes in social network platforms? Today’s rapidly growing creative companies must adopt social network platforms. Indeed, the “twenty-first century’s wealth comes from platforms” Thus “those who possess platforms dominate the wealth of the future” (Hirano & Hagiu, 2010). After the Lehman Brothers-initiated financial crisis, companies began developing platform strategies as a cutting-edge management method for assuring consistent and stable growth. Platform strategies call for gathering relevant groups of people together in a network that then creates new business. (Hirano & Hagiu, 2010) In this study, we study a social network platform to show how marketing management processes can be applied to social network platforms. Literature Review Social Network Platforms In recent years, social network platform sites such as Facebook, Twitter, and KakaoTalk have evolved to bring people together online. Social network services (SNS) are rapidly infiltrating daily lives and facilitating communications among people by means of computers (Correa et al., 2010; Powell, 2009). Users reside at the center of social platforms where they can socialize and express a wide range of behaviors. As a force for change, social platforms are influencing marketing strategies as well. Advertising has been traditionally one-way communication from company to customers through public media and portal sites. Recently, the paradigm has changed (Yeo, 2014): companies establish relationship with customers through social platforms that allow them to talk with customers directly, exchange opinions, and share ideas. As a result, large-scale corporations, mid-sized/small companies, and one-owner companies have turned their attention to social platforms (Jhun, 2013). Moreover, the revolutionary wave has affected such diverse areas as politics, economics, society, culture, and environmental causes. Researchers have responded to social platform developments with studies that deal with concept, construction, policy, development, spatial information, social platforms, and governmental roles (Choi et al., 2012), and that deal with social platform’s social influences and future directions (Lee & Jung, 2011). Researchers have studied functions and utilization of social platform using web services and policies to support collaborative research (Pignotti & Edwards, 2012), sharing shopping information (Der Ho et al., 2010), customer engagement (Cheung, Lee, & Jin, 2011), and senior social platforms (Farkas, 2010). Social platforms emerged so recently that academic studies have failed to keep up with the urgent need to study the phenomena realistically (Yeo, 2013).
