The Gross Ecosystem Product (GEP) accounting served as both a crucial step in promoting the realization of ecological products and an important measure for implementing the "lucid waters and lush mountains are invaluable assets" concept. Based on a statistical perspective, this study systematically constructed a theoretical framework for GEP accounting, validated the framework through case studies, and highlighted its policy application value. The study yielded the following key conclusions: (1) The supply and use tables provided systematic technical tools for GEP accounting, enabling clear visualization of the entire production-to-consumption processes of ecological products. (2) The accounting framework incorporating intermediate services not only revealed interregional ecological interdependencies, but also quantified net ecological contributions of individual regions, thereby establishing a scientific basis for transregional ecological compensation. (3) The potential-adjusted accounting framework effectively distinguished between actual ecological supply and sustainable supply capacity, serving as an early warning tool for identifying ecological overload risks. (4) The combined application of these three accounting frameworks could address diverse policy scenario requirements.
