In the process of implementing data openness between banks and fin-tech companies, as the breadth and depth of cooperation between banks and enterprises continue to increase, there is a risk of “too much correlation to fail” and “too many links to fail”. There are problems with the implementation of financial data openness by regulatory agencies for banks and fin-tech enterprises, such as the ambiguity of regulatory responsibilities, the emphasis on financial regulatory goals, and the lag in regulatory methods. To address these issues, it is necessary to clarify the responsibilities of financial regulatory agencies, establish a collaborative mechanism for financial regulation, coordinate the types of risks in bank enterprise cooperation, achieve the technical implementation of financial regulatory measures and the design of regulatory systems, obtain regulatory data in real time, establish a hierarchical regulatory system for bank enterprise cooperation to improve the regulatory path, and ensure the rational and legal use of financial data in bank enterprise cooperation.
