Analysis Of Influencing Factors Of Net Interest Margin Of Commercial Banks In China Under The Interest Rate Marketization

Net interest margin as an important way to profit for our country commercial bank, determines the competitiveness of commercial banks and its position in the market.At present, our country commercial bank business is still to rely on the net interest margin of the traditional business, intermediate business and off balance sheet business earned income in commercial banks operating income ratio is still small.But with the deepening of interest rate marketization, the impact it brings to the commercial bank profit mode is very important, to analysis and study of our country Commercial Bank net interest margin factor of influencing the reform net interest margin management become the imminent problems.Under the background of interest rate liberalization, the decisive factor of net interest margin and its type of action is of great significance to the healthy development of the stability of the financial system to solve the problem, the profitability of commercial banks.Previous research from this paper is based on the "market leader" model, combined with the reality of our country economy, to analysis our country Commercial Bank net interest margin factors.And then combined with the historical data of2004-2013years to make an empirical analysis of Industrial and Commercial Bank of China, Ningbo Bank, Guangda Bank, three representative commercial bank, and by the time series data to set up linear regression model, though the ordinary least squares method specific test significantly affects our country Commercial Bank net interest margin factors.Then through the empirical results comparing the three bank, to find out the influence factors of Ningbo Bank net interest margin higher.According to the research results at home and abroad, combining the national conditions and the reality of the economic status of China,this paper selected factors including the opportunity cost of bank reserve,risk preference, credit risk,the structure of assets and liabilities,management efficiency,market power,the rate of economic growth, benchmark spread eight effecting factors of commercial bank net interest margin.Through the analysis i found, eight factors that affect the commercial bank’s net interest margin in this theoretical analysis, analysis of the part in the empirical study found their net interest of three listed state-owned commercial banks affected slightly different results, influence the direction with the theory analysis difference.Among them, in the empirical analysis of Ningbo Bank, the theoretical analysis of the eight net interest margin factors impact on net interest margins are statistically significant, effect is basically consistent with the theoretical analysis of the direction of management efficiency, especially effect on the net interest margin is the most significant.The analytical results of the Industrial and Commercial Bank of China speaking, reserve assets of opportunity cost, risk preference, the structure of assets and liabilities and benchmark spread of the bank net interest margin of influence is not statistically significant, the influence factor of the remaining net interest margins are statistically significant, the management efficiency is also the greatest impact factor.And the results of the empirical analysis of Guangda Bank display, eight factors which influence on the commercial bank’s net interest margin in this paper that, in addition to reserve assets of opportunity cost, the other seven factors are statistically significant impact on the Guangda Bank net interest margin, and management efficiency is also the most obvious factor, regression coefficient the maximum.In addition, through the empirical comparative analysis found that, in the management efficiency influence factor regression coefficient of similar cases, the other two bank Ningbo Bank net interest ratio is high, the reason is the Ningbo Bank is better than other banks in the management efficiency.The innovation of this paper lies in the listed commercial banks in accordance with the net interest margin level is divided into three categories:higher net interest margin, net interest margin of commercial bank middle business bank and lower net interest margin of commercial banks. Then the empirical analysis, and then the results were analyzed and compared, and find out the reason for significant effects of commercial bank’s net interest margin level.In addition, this paper combined the study of predecessor, which has been relatively mature model based on relative identity, select the net interest margin factor influence analysis of commercial bank’s net interest margin management, summed up the results of previous studies further on search for the net interest margin influence factors.Finally, according to the previous part of the content, that the management of commercial bank efficiency are significant reasons of China’s commercial bank’s net interest margin, based on the net income of listed commercial banks in our country is poor development has made the brief analysis.Through the empirical analysis in this paper puts forward some suggestions of the factors that impact, commercial bank deposit and loan structure, commercial bank profit mode innovation and business innovation transformation etc.In order to enhance the healthy development of the commercial bank net interest margin management, strengthening the financial system stability, avoiding financial risks, insuring the financial system better.
