Policy-based financing guarantees establish a risk-sharing model. In the event of enterprise default, the compensation process is initiated and the bank recognizes the losses incurred in advance. The government, bank, and guarantee institution simultaneously provide full compensation according to the agreed proportion, greatly reducing the compensation risk of the guarantee company and enhancing its sustainable development capabilities.
