Against the dual strategic backdrop of building the Hainan Free Trade Port and establishing an international tourism and consumption hub, the deep integration of revolutionary culture—a vital component of Hainan’s cultural resources—with the cultural tourism industry has emerged as a core driving force for high-quality industrial development. With nearly a thousand revolutionary heritage sites and distinctive red cultural IPs, Hainan possesses inherent advantages to propel the upgrading of its cultural tourism sector. This paper systematically examines Hainan’s red cultural resources and development practices within the theoretical framework of resource development and industrial integration. The paper analyzes current challenges, including insufficient resource utilization and lagging product innovation, proposing a four-dimensional development path: “resource revitalization → product innovation → industrial integration → ecosystem construction.” This approach provides theoretical support and practical guidance for empowering Hainan’s cultural tourism industry through red culture development.
