Analysis of Vertical Federated Technology for Effective Financing of Small and Medium-Sized Enterprises Based on Three-Party Evolutionary Game

Core enterprises can provide effective assistance for financing small and medium-sized enterprises (SMEs). Promoting data sharing between both parties is of great significance. However, a real issue is that core enterprises may not be willing to share information for SMEs or financial institutions due to concerns about privacy leakage. Vertical federated technology (VFT) considers the privacy protection issues of distributed data and has become an advanced technology for solving distributed data cooperation. But its execution is also influenced by various factors. This article conducts a dynamic evolutionary game analysis of cooperation based on the new technology. A three-party evolutionary game model was constructed. It highlights the influencing factors of the application of VFT in the cooperation for financing of SMEs. The findings indicate that VFT technology can be considered an effective strategy for solving the financing problem of SMEs under specific conditions.
