| Summary: | With the growing popularity of B2B e-marketplaces, increasing numbers of
organizations are endeavouring to utilize this medium in their business activities.
However, the present knowledge regarding B2B e-marketplace adoption processes is still
limited. Therefore, the present study investigates circumstances under which
organizations adopt B2B e-marketplaces. More specifically, it is primarily concerned
with the factors motivating an organization's participation in B2B e-marketplaces from
the purchasing manager's perspective, based on insights and observations obtained from
transaction cost economics. A single unified framework was developed based on
previous findings to investigate the emergence of efficiency motive within organizations,
and to analyze the role of this motivation in organizational participation processes. A
large-scale cross-sectional survey study targeted the membership of the Purchasing
Management Association of Canada (PMAC) was used for empirical validation of this
framework. Partial Least Squares (PLS) analysis was chosen to test the measurement
model and the conceptual model based on 466 usable responses obtained. The results
demonstrate that efficiency motive exerts a significant influence on intentions to adopt
B2B e-marketplaces, and reveal three transaction characteristics that significantly
contribute to the formulation of efficiency motive: frequency uncertainty of demand,
asset specificity, and market fragmentation.
