Unofficial AI-generated summary based on the public title and abstract. Not an official translation.

🔬研究者:This paper introduces a novel quantitative framework (Wood‑Force balance sheet) connecting ecological asset accounting with TNFD/ISSB standards, offering a mathematical basis for biodiversity finance research.

🏢実務担当者:The Wood‑Force model can be used to price biodiversity credit assets and improve green credit risk assessment, with demonstrated precision gains of 15-35% in Chinese cases.

🏛政策担当者:The paper demonstrates how a unified mathematical language can support mandatory nature disclosure frameworks and inform biodiversity finance policy, particularly for credit pricing standards.

The year 2026 marks a historic turning point in which global biodiversity finance is transitioning from institutional construction toward substantive capital deployment. China‘s green finance market is undergoing a systemic paradigm shift from a climate ‑ focused “ emission reduction narrative ” to a “ systems ecology ” approach that encompasses biodiversity conservation. The GRI 101 Biodiversity Standard came into effect on 1 January 2026, the Taskforce on Nature ‑ related Financial Disclosures (TNFD) has completed multiple sector ‑ specific application guidance documents, and the International Sustainability Standards Board (ISSB) announced that it will publish an exposure draft on nature ‑ related disclosures in October 2026 — all signalling that global natural capital information is moving from voluntary disclosure toward mandatory institutional arrangements. However, the pressing challenge confronting biodiversity finance is that the TNFD’s LEAP approach provides a process framework, GRI 101 establishes disclosure parameters, and the ISSB is driving global baseline alignment, yet none offers a unified mathematical language capable of systematically quantifying “dependencies — impacts — risks — opportunities” into comparable, auditable, and financially measurable metrics. Based on the Wood ‑ Force · RCE ‑ B/S model within the eight ‑ dimensional framework of Prim ‑ Lex theory (Economic Climatology), this paper establishes for the first time a mathematical mapping matrix between the eight ‑ dimensional ecological asset accounting system and the TNFD/ISSB/GRI 101 natural disclosure standards: the Net Climate Equity equation   precisely maps onto the TNFD core dependency ‑ impact indicators; the red ‑ yellow ‑ green three ‑ colour zoning rule of the GCSOS model aligns with the spatial data stratification of the TNFD LEAP methodology; the G ‑ REMI civilizational resilience index interfaces with the SASB biodiversity disclosure metrics; and the complexified unified field of the Wood ‑ Force balance sheet serves as a quantitative yardstick for enterprise ‑ level compliance assessment under the forthcoming ISSB nature exposure draft. Using the latest practical cases of biodiversity finance in China as empirical anchors — including the RMB 200 million TNFD ‑ aligned biodiversity loan from Industrial Bank, the RMB 527 million “ biodiversity protection special loan ” composite financing model from Postal Savings Bank, the RMB 215 million “ Green Mining + Biodiversity ” special loan in Shanxi Province, and the more than 15 categories of green financial products (with loan balances exceeding RMB 32 billion) derived from the GEP accounting system in Lishui City — this paper incorporates these cases into the Prim ‑ Lex financial accounting framework, demonstrating a complete technical pathway for pricing biodiversity credit assets through eight ‑ dimensional Prim ‑ Lex diagnosis and the Wood ‑ Force balance sheet. Empirical simulation shows that incorporating the Wood ‑ Force balance sheet into biodiversity finance project assessment improves the precision of green credit risk pricing by approximately 15%–25%, enhances the accuracy of asset collateral valuation by approximately 20%–30%, and increases the information exchange efficiency of cross ‑ border biodiversity finance projects by approximately 25%–35%. These results provide a globally unified technical benchmark for differentiated green credit pricing, biodiversity bond rating, and project screening by international biodiversity funds.
