In this paper the interactive nature of the buyer-supplier relationship in
the era of electronic commerce will be explored. Through broad range review
s of previous works on relevant topics, this paper proposes a conceptual mo
del to demonstrate the rationale of the buyer-supplier interaction with inf
ormation service provider's mediation in the electronic commerce environmen
t. By taking information service provider as an intermediary, our model inc
ludes buyer, supplier and information service provider as three major parti
es. The rationale of interaction between buyer and supplier is rooted in in
dividual party's objectives which usually fall into two categories: cost an
d quality. This model also takes the following three items into considerati
on: (1) information flow, (2) flow of goods or services, and (3) feedback i
nformation. Finally, our study provides the implications and suggests that
the following factors can affect the way buyer and supplier interact: the m
anagerial practices, the types of relationship, and the extent to which com
panies dominate the market. (C) 2001 Published by Elsevier Science Ltd.
