Dynamics in digital finance and its impact on SME financing

Employing the Complex Adaptive System (CAS) framework, we analyzed the evolution of digitally transformed financial networks, underscoring the pivotal role of adaptation and learning among network participants. Government funds supporting banks and platforms in digital transformation prove more effective than direct subsidies to SMEs. Achieving sustainable development requires an optimal balance between investment and efficiency due to the impact of digitalization costs on constructing digital financial networks. The study advocates for a long-term microcredit financing mode tailored to SMEs, aiding them in maintaining financial stability. Additionally, intermediary nodes within the network, such as credit rating companies, can facilitate information sharing, thereby fostering the growth of digital financial networks. This heightened information sharing enhances the payoff for each subject and reduces financing constraints. Furthermore, the study establishes that digital financial networks can alleviate the repercussions of unforeseen events, such as the COVID-19 pandemic. Finally, empirical analysis of the Beijing University Inclusive Finance Index data and financial records of Chinese SMEs listed on the New Third Board from 2016 to 2018 confirms that digital finance can alleviate the financing constraints of SMEs. In summary, the progression of digital financial networks is intricate, necessitating a thorough comprehension of diverse factors. The government is encouraged to guide the enhancement of relevant systems and regulations, bolstering supervision, and facilitating the high-quality development of digital finance networks.
