Abstract:The booming development of financial technology(Fintech) has provided new ideas for improving the total factor productivity(TFP) of China's commercial banks. However, the specific impact and mechanism of Fintech on the TFP of commercial banks are not yet clear. Therefore, based on panel data from 58 commercial banks in China between 2012 and 2021, this study employs frontier analysis, fixed effects models, and mediation effects models to empirically analyze the influence of Fintech on the TFP of commercial banks in China. The results showed that: (1) fintech has a positive effect on the TFP of commercial banks; (2) Fintech can drive up the TFP of commercial banks by influencing the operational management status, human capital structure, and innovation capability of commercial banks, and their mediating effect decreases accordingly; (3) Fintech has improved the TFP of commercial banks with different property rights structures to varying degrees, and has a greater impact on listed commercial banks and commercial banks with more branches. Therefore, optimizing the development environment of fintech, fostering fintech talents, and accelerating the digital transformation process of commercial banks are of utmost importance in enhancing the core competitiveness of commercial banks.
