Conceptual model that both technology and volume uncertainty promote exchange partners to rely on the network norm of information sharing which is the necessary ingredient of the network embeddedness. Data was collected from the 143 manufacturers in high-tech market in which triadic relationships among the manufacturers (seller), their first vendors (first buyers), and the second vendors (customers of the first buyers) in high-tech markets were particularly focused. Results from the structural equation model and multiple regression analysis reveal that while the technological uncertainty has a positive effect on the network norm of information sharing, the volume uncertainty is not statistically significant. In addition, we find that there existsthe mediator effect of the network norm of information sharing in the relation between the uncertainties and the network embeddedness.
