Can mobile internet finance really have a positive impact on commercial banks?

As a financial innovation integrating network technology and traditional financial services, the rapid development of mobile internet finance has a direct impact on commercial banking business. However, due to the immaturity of the financial industry in developing countries, many commercial banks are facing policy uncertainty risks. In this paper, we select representative commercial banks to explore the variation of the performance brought by mobile internet finance. Empirical studies show that the performance of commercial banks has declined under the impact of mobile internet finance. The reform of market-oriented interest rate can alleviate the decline of commercial banks' performance. This proves that the early national policy of interest rate marketisation (IRM) has achieved results in promoting the liberalisation of the financial industry. The policy of IRM adopted by the country can enhance the ability of large commercial banks to dispose of the challenges of mobile internet finance.
