This study focuses on continued knowledge contribution. We hypothesize that continued knowledge contribution of members in opinion-sharing communities is influenced by five factors: the number of reviews written, the average of helpfulness scores received from other members, the average of helpfulness scores given to other members, the ratio of the number of negative reviews to the total number of reviews, and the number of trustors. We collect data from Epinions.com and find that these five factors have significiant impacts on continued knowledge contribution. These findings have significant theoretical and practical implications for knolwedge sharing.
