Core Viewpoint - The China Bank Shiyan Branch has introduced an innovative "sand and gravel resource replacement" financing model to address funding challenges in the governance of the Langhe River basin, which is crucial for the water source safety of the South-to-North Water Diversion Project [1]. Group 1: Project Overview - The Langhe River is an important tributary of the Danjiangkou Reservoir, and its governance directly impacts the water source safety of the South-to-North Water Diversion Project [1]. - River governance projects typically have strong public welfare characteristics and long investment return cycles, making funding a key bottleneck for sustainable governance and ecological benefits [1]. Group 2: Financing Model - The "sand and gravel resource replacement" financing scheme integrates river dredging projects with the rational development of sand and gravel resources, using sales revenue from the sand and gravel as the primary repayment source [1]. - A closed-loop financing chain is established through the model, which includes governance, sand mining, revenue generation, and repayment [1]. Group 3: Collaborative Operation - The financing model involves a collaborative operational structure comprising the government, platform companies, entrusted processing enterprises, and sales companies, facilitating efficient conversion of ecological governance and resource value [1]. Group 4: Financial Details - In 2025, the Langhe River governance project successfully obtained a credit approval of 200 million yuan, with 120 million yuan drawn in the first year [1]. - The China Bank Shiyan Branch has set a 10-year loan term with a 2-year grace period to align with the sand and gravel revenue cycle and long-term governance needs [2]. Group 5: Risk Management - A "guarantee + pledge" combination collateral model is employed for risk prevention, establishing a multi-dimensional safety net for credit [2].
