Research On The Relationship Between Users' Social Capital,Sense Of Virtual Community And Knowledge Contribution In The Social Q&A Community

With the development of information technology,especially the development of the Internet,the amount of knowledge has grown exponentially.More and more people are involved in the process of knowledge production and dissemination.Meanwhile,Socialized question and answer communities are produced,where people can ask,answer and discuss questions about common practices or interests.The social Q&A community enhances the regular Q&A system through social networking,helping to establish social connections between users,issues and topics.Therefore,it is a valuable direction to explore the knowledge contribution behavior of socialized question and answer community.Through the study of the previous literature,it can be seen that there have been many studies on the knowledge contribution behavior of users by domestic and foreign scholars in different fields based on social capital theory,social exchange theory and incentive theory.However,there are few studies about the knowledge contribution of socialized Q&A community.So this paper studies the user knowledge contribution behavior in the socialize contribution of socialized question and answer community from the perspective of social capital.In the existing researches on the influence of social capital on the knowledge,there is no more subdivision of the social capital according to the actual situation of socialized Q&A community,so as to further study the function principle of its knowledge contribution to users.Based on the analysis of previous literatures and the characteristics of domestic socialized Q&A communities,this study divides social capital into three dimensions,namely,structural capital,relational capital and cognitive capital,and constructs a research model that takes the sense of virtual community as the intermediary variable and the influence of social capital on users' knowledge contribution.In this paper,304 valid questionnaires were collected from users with experience in the socialized Q&A community.Statistical analysis was applied to analyze the data,and the following conclusions were drawn: There is a positive correlation between social interaction,community identity,knowledge reciprocity,shared vision,perceived similarity and user's knowledge contribution behavior;There is a positive correlation between social interaction,community identity,knowledge reciprocity,shared vision,perceived similarity and user's sense of virtual community;There is a positive correlation between the sense of virtual community and user knowledge contribution;The sense of virtual community plays a partial mediating role in the interaction mechanism of social interaction and shared vision on user knowledge contribution;the sense of virtual community plays a complete mediating role in the interaction mechanism of community identity,knowledge reciprocity and perceived similarity on user knowledge contribution.This study proposes effective management methods for community builders based on the mechanism of influencing factors,attaches importance to various factors affecting users' knowledge contribution behavior,and attracts more community members to participat e in socialized question and answer communities.This study also point to the limitations of this study and the outlook for future research.
