The document analyzes Denmark's successful wind turbine industry using Porter's Diamond Framework and Mathews' Dynamic Competitive Forces Framework. It explains how factor conditions like natural resources and skills, as well as firm strategies, demand conditions, supporting industries, government policies, and external chances contributed to the growth of the industry. In particular, it highlights the wind cluster in Aarhus, home to many global companies including Vestas, the world's largest turbine manufacturer. It describes how various actors in the cluster, including designers, manufacturers, suppliers, institutions, and policymakers collaborated over time to build capabilities and progressively improve wind turbine technology through a process of "learning by doing."
