| China is a large country of deposits,and deposit security is very important to China’s financial stability.In May 2015,China began to implement the deposit insurance system,which had a certain diversion effect on commercial bank deposits.With the extension of the implementation year of China’s deposit insurance system,the diversion impact of the deposit insurance system on China’s commercial bank deposits also changed.There are many factors affecting the deposit diversion of commercial banks.By referring to the previous literature on deposit diversion and deposit insurance system of commercial banks,this paper selects relevant variables,constructs a data model,and selects the deposit data of 65 periods before and after China’s deposit insurance system,that is,the deposit data of China’s commercial banks from January 2010 to October 2020,a total of 130 periods,Based on the deposit data of commercial banks of different sizes and properties and the historical data of relevant deposit diversion variables,this paper explores the impact of deposit insurance system on the deposit diversion of commercial banks in China.Through empirical research,it is found that whether to implement the deposit insurance system,consumer price index,stock turnover,national housing boom index,interest rate of treasury bonds due one year later,loan growth rate,GDP growth rate and insurance income have an impact on the diversion of deposits of commercial banks;The deposit insurance system has a positive effect on the deposits of small and medium-sized commercial banks and a negative effect on the deposits of regional commercial banks.Regional commercial banks need to take measures to slow down the more serious deposit diversion effect of the deposit insurance system compared with the deposits of large state-owned commercial banks,such as strengthening the cultivation of deposit marketing ability,expanding the scope of intermediate business income,reducing the proportion of interest income business and improving customer stickiness,strengthening investment in scientific and technological research and development,and obtaining competitive advantages in products and services,Give risk compensation to high net worth customers with assets of more than 500000,improve the corporate governance structure and enhance the quality of shareholders.At the same time,regulators should timely adjust the implementation and reform of the deposit insurance system and give reasonable play to the guarantee role of the deposit insurance system. |
