| Financial technology is born from the integration of technology and finance.While Internet enterprises continue to extend to the financial industry with the development of the times,traditional commercial banks are also trying to seek the assistance of science and technology,looking forward to achieving their own sustainable innovation and development.The emerging financial industry has realized the improvement of service efficiency by using financial technology,the popularization of mobile channels,effective customer screening and differential pricing,and become more accurate and powerful in risk assessment and control.In contrast with these powerful advantages,the traditional banking industry has suffered a great impact,and its business situation has become increasingly severe.However,the development of this emerging financial industry has brought competition and impact,and also provided the commercial banks with the power of self-innovation and technological progress.For a long time,commercial banks have been firmly in the leading position of China’s financial system and have strong leadership significance.Their operating efficiency is not only related to the stability of the financial market,but also plays an irreplaceable important role in the high-quality development of the economy.Commercial banks have attracted more long-tailed customers through the application of financial technology,expanded the scope of their business services,and also played a certain role in promoting the optimal allocation of financial resources.The development of financial technology has stimulated banks to transform and upgrade from various aspects,and finally had a positive impact on their operating efficiency.Based on the above problems,this thesis selects 17 listed commercial banks in China from 2013 to 2021 as samples,uses text mining technology to obtain data,constructs the bank fintech development index by principal component analysis method and min-max standardization method,and uses the super-efficiency SBM model to measure the super-efficiency value of the above banks.The results show that: first,the overall development trend of financial technology of commercial banks in China is good,there are differences in the development level of different types of banks,and the level of financial technology of large commercial banks is relatively high;Second,on the whole,joint-stock banks and urban commercial banks are more efficient than large commercial banks and rural commercial banks.Third,the development of bank financial technology is conducive to improving the operational efficiency of commercial banks.Fourth,the development of bank fintech can affect the efficiency of commercial banks through two channels: the cost of capital effect and the intermediate business income effect.The development of financial technology has a positive impact on the efficiency of commercial banks by reducing the cost of capital and improving intermediate business income.Based on the research conclusions of this thesis,the following policy suggestions are put forward: Firstly,develop differentiated fintech development strategies based on different types of banks;Secondly,actively developing financial technology to help improve the efficiency of bank operations;Thirdly,increase efforts to develop intermediary business;Fourthly,reasonably reduce capital costs and expenses. |
