| In recent years, as Mainland Chinau0027s economy has entered the \"new normal\", \"interest rate marketization\" reforms deepening and the development of online information technology, Chinese commercial banks have begun to gradually transform into the diversification strategy. Through theoretical analysis and empirical model, this paper gives a concrete explanation of the relationship between diversification and bank operation performance.
In terms of theoretical analysis, firstly this paper introduces the scope economy theory, diversification theory, synergy theory and asset portfolio theory. Then, this paper analyzes the diversification indicators of nationalized banks, joint-stock banks and urban commercial banks in mainland China and related indicators of banking performance. This paper also reveals the development and changes of the income, assets and liabilities structure of the three types of banks. Finally, this paper proposes four hypotheses for empirical model testing through the analysis of the impact mechanism of bank income, asset and liability structure and bank performance.
In terms of empirical analysis, this paper uses the Diversification Index (DIVI/DIVA/DIVL) evolved from the Herfindahl Index (HHI) as explanatory variables and the banku0027s operating performance indicators (ROA/TQ/NPL/LCR/TAI) as explained variables, to establish a multivariate linear model based on Panel data. This paper uses the panel data of 25 A-share listed banks in the quarter of 2008-2017 to systematically analyze the relationship between commercial banksu0027 diversification and business performance. Subsequently, this paper makes a more in-depth analysis of the correlation between the types of the bank and the impact of diversification on business performance by dividing the sample into whether it is a joint-stock bank or a urban commercial bank.
Through the above analysis and research, the paper draws the final conclusion.The diversified operation of income and assets is conducive to improving the profitability of banks, but the diversification of liabilities is the opposite.The diversification is generally conducive to improving bank liquidity, but at the same time it will also sacrifice bank loan assets’ security.The diversification of assets and liabilities is conducive to improving bank growth, while income diversification has a negative impact on growth. At the same time, the paper also points out that the impact of diversification on bank performance vary in different bank types.In general, the diversification strategy has a stronger positive effect on the banku0027s operating performance, but the direction of diversification that should be focused on banks of different types is also different.
Finally, based on the above research results, this paper puts forward various suggestions from bank management strategy and the government supervision. The author hopes that these suggestions will help Chinese commercial banks adopt better diversification strategies and improving bank performance. |
