Multi-Stakeholder Collaboration and Multi-Level Community Participation Centred on the Provision of Non-Material Ecological Products Can Effectively Reconcile Strict Protection in Protected Areas with Local Community Development

The public-goods nature of ecological products and heterogeneous stakeholder interests mean that protected areas often face weak coordination, limited incentives, and uneven benefit distribution in the identification, transformation, and return of ecological value. Under increasingly strict conservation objectives, ecological product provision is shifting from direct resource use towards maintaining ecosystem functions and realising experiential value. This helps safeguard ecosystem integrity but raises demands on institutional pathways for value transformation and on the sustainability of community livelihoods. Using Pudacuo National Park in China as a case, this study develops an analytical framework linking supply–demand structures, value chains, and value co-creation, and applies policy document analysis, semi-structured interviews, field observation, and process tracing to examine mechanisms of ecological value realisation under strict conservation. The results show that: (1) a collaborative governance network integrating park authorities, local governments, and concession operators provides a stable organisational basis for ecological value identification and transformation; (2) strengthened provision of non-material ecological products reorients the supply system towards regulating and cultural services, driving a shift from material output to function- and experience-oriented provision; (3) a multi-level community participation model combines labour embedding, livelihood diversification, and institutionalised benefit return to form an ecological value return mechanism grounded in value co-creation. Together, these mechanisms support a relative balance between ecological protection and community development under strict protection and offer empirical insights into the institutional logic of ecological value realisation in strongly protected contexts.
