Abstract: Through in-depth interviews with 15 innovators in the metaverse sector, this study investigates effective pathways for digital economy industry development. Integrating collaborative governance and interactive governance theories, it examines the "Meta-academy" initiative in W City as a case study. The findings reveal that collaborative governance under the Accompanied Leadership framework effectively resolves market and administrative failures through tripartite coordination (state-market-society). This approach facilitates structural reorganization of party-society relations and enhances social mobilization of innovators. The Accompanied Leadership model operationalizes multi-stakeholder collaboration through three mechanisms: legal institutionalization of community organizations, identity recognition and regulatory compliance frameworks, and relational contract-based cooperation. These mechanisms expand operational spaces for youth innovation, stimulate endogenous industry growth, and provide theoretical insights for digital-era governance practices.
