Abstract
Enhancing efficiency is a critical objective of corporate management. While
numerous approaches to measure efficiency have been devised, this manuscript
suggests a new method referred to as dynamic network-based Data Envelopment
Analysis (DEA) as a more advanced procedure for examining transaction priorities
in any network based organization. Using dynamic network-based DEA it is
possible to detect system-wide impacts when marginal systemic changes occur.
This newer method was tested using data drawn from Mazda’s Yokokai keiretsu
to illustrate the effect that transactions among member firms in the network
have on sales revenues. The finding of the study are discussed based on
which managerial implications in the formulation of corporate strategy
are proffered. Study drawbacks are identified and avenues for future research
are suggested.
