Which of the following is not one of Porter's four determinants in the Diamond model?

• A. Factor conditions
• B. Demand conditions
• C. Innovation
• D. Related and Supporting industries

Answer: (C)

Porter's Diamond explains national competitiveness through four interrelated determinants: factor conditions, demand conditions, related and supporting industries, and firm strategy, structure and rivalry. Innovation is not one of these four. It tends to be influenced by how resources like skilled labor and infrastructure (factor conditions) are available, how demanding and sophisticated the domestic market is (demand conditions), how strong the supplier and related industries are (related and supporting industries), and how firms compete and organize themselves (firm strategy, structure and rivalry). So the item describing innovation isn’t one of the four determinants, even though innovation often results from the interplay of the others.
