Econometric Study On Operational Risk Of State-owned Commercial Banks:Based On Revenue Model

In recent years,in the field of commercial banks at home and abroad,because of extreme operational risk events,banks have suffered huge losses and even bankruptcy incidents from time to time.The sudden collapse of the bank at the end of last century made the global banking industry realize for the first time that the operational risk may have disastrous consequences for banks.With the occurrence of major operational risk loss events and the increasing amount of losses worldwide,operational risk management has gradually become an important part of commercial bank risk management.How to manage and measure operational risk effectively has become an urgent problem for commercial banks.The research on operational risk of commercial banks in China started relatively late,and has not yet formed a systematic theoretical framework.The lack of effective historical data makes the measurement of operational risk face great limitations.Therefore,it is of great theoretical value and practical significance to study the measurement of operational risk,especially for the accurate identification of operational risk and the construction of an effective measurement model.This paper is divided into five parts.The first part elaborates the seriousness of huge losses caused by operational risk incidents to banks,reveals the importance of operational risk management and measurement,determines research methods and technical routes,and analyses the innovation and shortcomings of this paper.The second part analyses the current situation of operational risk measurement of state-owned commercial banks in China,and expounds the limitations of various measurement methods in the New Basel Capital Accord and the applicability of income model in the existing f nancial environment of China.In the third part,according to the current situation of state-owned commercial banks in China,the explanatory variables affecting the net profit of banks are analyzed,and an income model suitable for the measurement of operational risk of state-owned commercial banks in China is constructed.In the fourth part,five state-owned commercial banks in China are taken as the research objects.Using the financial data collected from the public data and some macroeconomic indicators,regression analysis is carried out by using the income model,which verifies the feasibility of the model.In the fifth part of the article,according to the results of empirical analysis,this paper puts forward countermeasures to strengthen operational risk management and measurement in China.
