Cluster-based industrialization in China allowed thousands of small, specialized firms to coordinate production through informal networks. This dispersed production model circumvented constraints on access to capital by allowing firms to specialize in individual production steps and pool resources. Key to this model was the role of local governments in providing public goods like infrastructure, marketplaces, and training to support firm clustering and growth. The cashmere sweater cluster of Puyuan, China became one of the "world factories" through this approach, with family workshops and merchants coordinating across the town.
