A Research On The Effectiveness And Relative Influence Factors Of Commercial Banks Under The Capital And Liquidity Constraint

In recent years,under the tightened supervision and holding the bottom line that preventing systemic financial risk,Chinese government inducted commercial banks reinforce the prevention and control of risks,timely resolved various financial hazards,ensure the safety and stability of commercial banks operation,and strive to prevent and resolve financial risks.Under this background,this thesis conducts a research to analyzes the influencing factors of commercial banks' efficiency with the constrain of capital sufficiency and liquidity.And it is expected that some reference might be provided for commercial banks to raise efficiency under the strict supervision.Based on the research approach: theoretical analysis-facts presented-empirical analysisconclusion and suggestion,this thesis explores the efficiency,as well as its influencing factors,of Chinese commercial banks.Firstly,this thesis introduces the research background,reviews relevant literatures,and then analyzes the mechanism that capital and liquidity influence the efficiency of commercial banks.Secondly,the primary regulatory policies from 2017 to 2018 are simply teased,and at the same time the influencing of the polices on commercial banks is analyzed,which lies a foundation for the following empirical analysis.Thirdly,taking number of employee,fixed assets,total deposits and interest income as the output indictors,this thesis measures and analyzes the TE,PTE,SE and SSE of commercial banks,with the method of DEA.At the same time,under the capital sufficiency and liquidity constrain and from the perspective of income and assets,the Tobit model is applied to analyze the influencing factors of commercial bank efficiency,with SSE as the explained variable.At last,some policy suggestions are given according to the theoretical and empirical results.According to the analysis above,conclusions are drawn as below:Firstly,from the angle of efficiency,the efficiency of commercial banks differs.Generally speaking,the average TE of stock-holding banks is larger than that of large-scale commercial banks and other listed banks.Comparing to large-scale and other listed banks,stock-holding banks have different PTE.Stock-holding banks and other listed banks are always in the increasing stage of scale return,and among the 29 commercial banks,CCB is always in the leading surface.Secondly,capital and liquidity constrain the development of commercial banks.Through the empirical analysis,it is found that there exists a negative relationship between capital sufficiency,pure stable capital ratio and commercial banks' efficiency,which suggests that commercial banks are affected by tightened regulations.Thirdly,diversification of income and optimization of assets and liability structure can increase the efficiency of commercial banks.empirical analysis shows that income,assets and liability factors have significant relationship with commercial banks' efficiency and the coefficients of assets and liquidity constrain decrease,which suggests that by realizing income diversification and assetsliability optimization,commercial banks not only increase their efficiency,but also offset the influence of capital and liquidity constrain on some degrees.The main contribution of this thesis are:firstly,by reviewing the literatures from 2017-2018 and combining indicators such as non-interest income,this thesis calculates the TE,PTE,SE,and SSE of commercial banks;secondly,the pure assets ratio is introduced as the liquidity constrain,and with premises of capital and liquidity constrain,the influence of which on commercial banks' efficiency is analyzed from the perspective of income and liability;and at last,some suggestions about strengthening compliance management of liability diversification,pushing asset operations back to origin,optimizing liability structure,and developing financial technology are given carefully.
