Under the background of ecological civilization development, mine ecological restoration has evolved from single-purpose environmental remediation toward the transformation of ecological products value. Focusing on Jiangxi Province, a typical southern hilly and mountainous region, a multi-case comparative analysis method was adopted to systematically examine the synergistic pathways between mine ecological restoration and ecological product value realization. Representative abandoned mine restoration projects in Jiangxi Province were selected to comparatively analyze policy instrument application, market-oriented operational mechanisms, multi-stakeholder collaboration modes, and value realization performance, thereby revealing both common characteristics and differences among synergistic pathways. The results indicate that Jiangxi Province has transformed abandoned mines into ecological products such as cultivated land, carbon sinks, and cultural tourism resources through innovative "ecological restoration+" diversified models, while establishing a full-chain value realization mechanism integrating restoration, transformation and value appreciation. Policy support, market-oriented operation, and multi-stakeholder collaboration constitute the three core elements underpinning the efficient functioning of this mechanism. However, constraints related to funding and technology, the absence of clear responsibility and accountability mechanisms, immature market systems, and insufficient policy coordination remain the major obstacles. The obtained results provide replicable and transferable practical pathways for promoting the coordinated enhancement of mine ecological restoration and ecological product value realization in southern hilly and mountainous regions.
