Abstract
Though concept of reverse logistics has been discussed by some scholars and specialists, there is still no general consensus about its definition. It has often been defined ambiguously and is not clearly defined. In order to evolve this field of research, we should reconsider the concept with a view to various elements. This paper reviews the past research results and examines the concept with focusing on cost saving behavior or competitive strategy. Then it points out that these days major companies have increasingly attached importance to reverse logistics as their own strategic measure. Finally, it synthetically reviews reverse logistics in terms of efficiency, strategy and sociality.
