The literature on electronic commerce and electronic marketplaces has long
recognized the importance of intermediaries and the functions they serve. T
he Internet is most often discussed in connection with digital intermediari
es as the displacement of traditional intermediaries. This article proposes
a new conceptual framework For understanding how competition in business-t
o-business (B2B) electronic commerce in the presence of information technol
ogy (IT) innovations changes firm-level strategy choices and the structure
of the marketplace. It also identifies and discusses the economic forces th
at lead to these changes, and in this context describes a recurring pattern
of intermediation, disintermediation, and reintermediation through an "IDR
Framework." The article explains the impetus for technological reintermedi
ation, where a disenfranchised traditional player is able to compete again
by leveraging technological innovations with cospecialized assets. This per
spective is built with the support of relevant literature from severe I ref
erence disciplines and with evidence from a field study of intermediation o
n the Internet in the corporate travel industry. The analysis reveals that
traditional travel firms have access to a range of strategies that enable t
hem to avoid disintermediation and retain highly profit able central roles
in the marketplace in the long run.
