Postal Savings Bank of China & NorthKing  launched a customised program called One County, One Product, leveraging its data-driven strategy to identify high-potential agricultural products in each county by integrating government data, e-commerce information, and the bank's own survey data, and applying big data analytics technology. In addition to traditional supply chain loans, the bank also provides rural individuals and corporate customers with a comprehensive financial ecosystem that includes insurance, payment and wealth management services. The winning program includes the development of necessary logistics networks and e-commerce infrastructure to facilitate product distribution. By implementing and disbursing RMB 300 billion ($42 billion) in loans across over 1,000 counties, it demonstrates scalability and quantifiable economic impact. Its innovative credit assessment system uses machine learning algorithms to provide more accurate evaluations of agricultural and rural clients, while the overall approach integrates financial inclusion with digital services, market access support, and agricultural technology to achieve sustainable rural economic growth.
