Abstract: Against the backdrop of the in-depth advancement of the Digital China initiative and the " dual carbon" goals, forest parks, as an important carrier of the forest tourism and forest health and wellness industries, play an irreplaceable role in the transformation and upgrading of the forestry and grassland economy and the value realization of ecological products through their high-quality green development. We employ the super-efficiency SBM-GML model to measure the green total factor productivity of forest parks in 30 provinces of China from 2005 to 2020, and investigate the enabling effect, underlying mechanisms and heterogeneity characteristics of digital infrastructure on the aforementioned GTFP. The results show that digital infrastructure exerts a significant positive driving effect on the GTFP of forest parks. Diversification level and ecological carrying capacity serve as two pathways through which digital infrastructure exerts its enabling effect. This effect exhibits significant multidimensional heterogeneity: it is significantly positive in the eastern region, in regions with high forest resource endowments, and in regions with a high industrial structure, whereas it remains insignificant in the central and western regions, in regions with low resource endowments, and in regions with a low industrial structure. Accordingly, targeted policy recommendations are proposed, including region-specific measures, depth determined by resource endowments, and enabling pathways shaped by industrial structure.
