The document discusses clusters, which are geographic concentrations of related companies and institutions in a particular field. Clusters arise because they raise productivity by providing local assets and access to other firms and infrastructure. Location affects competitive advantage through its influence on productivity and productivity growth. The development of well-functioning clusters is essential for moving economies to an advanced stage. Clusters increase productivity, innovation capacity, and stimulate new business growth. Government policy can focus on removing constraints to improve cluster productivity rather than distorting competition. Micro-cluster initiatives in Catalonia identified industry strengths and weaknesses, created consensus visions, and strategies to improve market access and upgrading.
