摘要:This research studies the relationship between well-being and knowledge sharing. While user innovation has garnered greater attention in recent years, the market has failed to properly incentivize the diffusion of user innovations. This study proposes that this shortcoming could be resolved through a consumer-to-consumer (C-to-C) marketplace and sheds light on non-financial benefits for the contributors, specifically, how knowledge sharing impacts contributor well-being. This research consists of two online survey studies. In both studies, the level of well-being was compared between knowledge sharing contributors and a control group using a scale developed in positive psychology. This study empirically shows that participation in knowledge sharing has a significant positive impact on contributor well-being. In a C-to-C marketplace, contributors diffuse and monetize their creations themselves, resulting in increased well-being. Contributing to knowledge sharing may be a sufficient incentive for user innovators to diffuse their innovations. The findings of this study will gain significance as the utilization of personal knowledge increases due to the expansion of the C-to-C business and the paradigm shift in work style.
