| In recent years,with the deepening of interest rate liberalization reform and financial openness,and the development of Internet finance,the competition and challenges faced by China’s commercial banks have intensified.During the "14th Five-Year Plan" period,the high-quality social and economic development requires more advanced financial services.As a significant part of the financial system,commercial banks undertake the important mission of better serving the development of the real economy.Under the background of the coexistence of challenges and responsibilities,the research on the operational efficiency can not only find out the operational conditions and differences of China’s commercial banks,but also clarify the efficiency improvement direction of each commercial bank,and put forward targeted suggestions,which is of great significance for commercial banks to better cope with challenges and take responsibility in the new era.The current paper divides the operational process of 36 China’s commercial banks into the production stage(absorbing funds)and the profitability stage(utilizing funds)and divides these banks into four groups according to their nature.Then this paper employs an improved Data Envelopment Analysis model(DEA)to calculate the operational efficiency of sample commercial banks from 2013 to 2020.To a certain extent,the model deals with the problem that the existing DEA models containing undesirable outputs may cause out-oforder efficiency evaluation results.In addition,the model considers the shared inputs of commercial banks in each operational stage and the influence of the "Leader-Follower"relationship in each operational stage on the allocation of shared inputs.The empirical results show that:(1)The operational efficiency of 36 China’s commercial banks has great room for improvement,and the efficiency of the profitability stage is significantly lower than that of the production stage;(2)The efficiency of state-owned commercial banks is higher than that of non-state-owned commercial banks both in the production stage and profitability stage;(3)Improving management capabilities is the main direction for most commercial banks to improve efficiency of the production stage,while in the profitability stage,the direction of efficiency improvement varies among commercial banks;(4)Diversification of income can significantly improve the operational efficiency of commercial banks.Finally,based on the empirical results,this paper puts forward some targeted suggestions. |
