Structure-Conduct-Performance Analysis

The structure-conduct-performance (SCP) paradigm is the foundational framework of industrial organization, holding that the structure of an industry shapes the conduct of the firms within it, which in turn determines their performance. In the Bain-Mason tradition, codified in Joe Bain's classic text, industries with high concentration and strong barriers to entry let firms behave in ways -- coordinated pricing, entry deterrence -- that yield persistently high profits, while fragmented, low-barrier industries push performance toward competitive levels. Michael Porter's 1981 article showed how this economic logic could be turned to the purposes of strategic management: where industrial organization treats structure as a determinant of an industry's average profitability and a target for antitrust policy, the strategist inverts it, asking how a firm can position itself within or reshape structure to earn above-normal returns. SCP analysis traces the structure-conduct-performance chain to explain and predict why some industries and firms are more profitable than others.
