초록

소셜 Q&A 사이트에서는 사용자들이 서로 질문하고 답변한 내용들이 실시간으로 저장되어, 지식 저장소로서 중요한 역할을 수행한다. 이러한 소셜 Q&A 사이트가 지속적으로 성장하려면 신규 질문자와 답변자가 지속적으로 유입되어야 한다. 하지만 선행 연구는 기존 사용자, 그 중에서도 답변자의 자발적 지식 공유에 주로 초점을 맞추었고, 신규 참여자에 대한 관심이 부족했다. 본 연구는 동기부여 어포던스 이론과 자기결정이론을 이론적 근거로 하여 신규 참여자들이 소셜 Q&A 사이트를 지속적으로 사용하도록 하는 요인에 대해서 살펴보았으며, 신규 참여자가 질문자인지 답변자인지에 따라 영향요인에 차이가 있는지도 알아보았다. 추가적으로, 전환 비용의 개념을 활용하여 신규 사용자의 다른 멤버 사이트에 대한 사전 경험이 지속사용 영향요인에 대해서 가지는 조절효과도 확인해 보았다. Stack Exchange Network의 5개 주요 사이트에서 수집된 25,000명의 온라인 활동 데이터를 로지스틱 회귀분석과 XGBoost 기법을 통해 분석한 결과, 자기결정 이론에서 제시하는 근본적인 욕구 세가지(역량, 자율, 관계)와 연관된 동기부여 어포던스들이 신규사용자의 지속사용 행위에 유의한 영향력을 보여주었다. 멤버 사이트 사용 경험은 사용자들의 전환비용을 높여서 지속사용 선행요인들의 영향력을 약화시켰다. 흥미로운 점으로, 규제 관련 어포던스는 신규 사용자 전체를 대상으로 한 분석에서 유의하지 않은 결과를 보였으나, 질문자와 답변자를 구분한 분석에서는 서로 반대 방향으로 유의한 영향력을 보였다.

Social Q&A sites, where individuals freely ask and answer each other online, play an important role as a public knowledge repository. For their sustainable growth, social Q&A sites constantly need new askers and new answerers. However, previous studies have focused only on answerers, with little attention to new users or askers. This study examines the factors encouraging new users to continue using social Q&A sites based on motivational affordance theory and self-determination theory, and also investigates whether the factors differ depending on the types of users (i.e., new asker vs. new answerer). In addition, the moderating effect of prior experience with a member Q&A site was examined. Using logistic regression and XGBoost, we analyzed online activity data from 25,000 users in the Stack Exchange Network and found that design elements with motivational affordances had significant impacts on new users' continuance behavior. The experience of a member Q&A site negatively moderated the influence of the antecedents of continuance behavior. Interestingly, the influence of editing was not significant in the analysis of new users as a whole, but was significant in the separate analyses of askers (significantly negative) and answerers (significantly positive).
