Abstract

Social capital theory involves the study of real or potential resources in the long-term development of community interpersonal relationships. Thus, three rounds of panel data from 208 users in three online communities were examined. The latent growth curve model was used to analyze the effects of the initial level and the growth rate of the norm of reciprocity and interpersonal trust on the initial level and the growth rate of knowledge sharing. The results demonstrated that (1) the initial level of the norm of reciprocity influenced the initial level of the quantity and quality of knowledge sharing; (2) the growth rate of the norm of reciprocity influenced the growth rate of the quantity and quality of knowledge sharing; (3) the initial level of interpersonal trust had a positive effect on the initial level of the quality of knowledge sharing; (4) and the growth rate of interpersonal trust had a positive effect on the growth rate of the quality of knowledge sharing.
