Research On The Impact Of Fintech On Commercial Banks

In recent years,with the rapid development of financial technology,many fintech enterprises have tried to carry out close business cooperation with traditional commercial banks,which has guided the new direction of the integration of finance and technology.This paper attempts to explore whether the development of fintech has caused a certain impact on the traditional banking system,and whether this impact can be reflected by the excess return rate of listed banks.In this paper,Fama French five factor model is used to estimate the expected excess return rate.By calculating the difference between the actual abnormal return and the expected abnormal return of listed banks,we can get the data of abnormal return of stock,and then get the cumulative average abnormal return(CAAR).This paper analyzes the CAAR and observes whether the CAAR in the window period fluctuates significantly before and after the time point of frequent interaction between listed banks and fintech,to discuss whether there is abnormal excess return in the stock before and after this time point,so as to determine whether the development of financial science and technology will have a certain impact on traditional commercial banks.It is found that the development of financial technology will indeed affect the excess return rate of commercial banks to a certain extent,and whether the impact is positive or negative does not exist independently from the environment of financial supervision.
