The demand for and complexity of youth care have increased, resulting in long waiting lists with serious consequences. Individual cases often exceed expertise of single care providers, making network collaboration essential but challenging. Municipal procurement decisions shape the youth care system, offering opportunities to enhance this collaboration. Through an archival study of procurement documents and a multiple casestudy with policymakers and care providers, this research identifies twelve policy incentives stimulating network collaboration within the system. Findings show that effective collaboration relies on well-designed procurement procedures and policy incentives across different levels, offering solutions to improve youth care in the Netherlands.
