:Large-scale land operators engaged in grain production often face significant financial demands but struggle to address these challenges through formal financial channels or traditional informal agricultural financing methods. In practice, they transfer financial pressures to the agricultural service system through “credit-based” operations. This approach is feasible for two main reasons: (1) service providers leverage these debt relationships as resources to secure market share; (2) local societies establish mechanisms to manage the risks associated with such debt relationships. Risk control is achieved through three key aspects: (1) horizontal and vertical cooperative networks within the service system reduce individual service providers' financial pressures and distribute debt risks; (2) based on local acquaintance societies and the service networks mentioned above, a robust social reputation mechanism is formed, significantly mitigating risks; (3) major agricultural input suppliers, who bear the primary financial burden, achieve a closed cash flow cycle by simultaneously offering drying and procurement services. They also integrate services across various providers, enabling unified debt management, thereby minimizing cash flow demands, financial pressures, and repayment risks. This service chain finance model successfully addresses the financing difficulties of large-scale land operators but does not resolve the issue of high financing costs. By leveraging the close connections within this production service system, diversified collateralized loan options can be developed to accelerate the implementation of inclusive financial services.
