TY - JOUR AB - Evaluates Wroe Alderson’s general theory of marketing as a possible platform for further developing Michael Porter’s ideas on strategic management. Alderson’s “transvection” and Porter’s “value system” are compared, and the uses of these concepts by their authors in developing approaches to achieving sustainable competitive advantage are contrasted. The potential for extension of each theory based on their similarities and differences is discussed. Presents examples showing how Alderson’s ideas may be used to resolve impasses in Porter’s work, and how recent empirical work testing Porter’s value system may be useful in extending and justifying Alderson’s transvection ideas. More generally, we suggest that Alderson’s general theory may provide a starting point for integrating Michael Porter’s ideas with the concepts from the “resource‐based view” of strategy, and that instances of independent formulation of nearly‐identical theories present special opportunities for scholars interested in both theory building and theory testing.
