Research On The Impact Of Maturity Mismatch On The Operating Efficiency Of Commercial Banks

'Short Deposit and Long Loan' of commercial banks' the management about funds will lead to maturity misdistribution,which has become an important factor affecting the operating efficiency in commercial banks.Especially,China's banking industry broken out the 'Money Shortage' in May 2013,has made the problem of liquidity of commercial banks once again becoming an important topic for discussion in the community.Although it has passed more than four years,to explore its deep-seated reasons and its possible impact is still one of the focus of academic attention.This paper focuses on the relationship between maturity misdistribution of commercial banks and the management efficiency and discusses the influence mechanisms and influence effects of maturity misdistribution on the operating efficiency of commercial banks from the perspectives of theoretical analysis and empirical analysis.The paper first defines the concept of maturity misdistribution,and further reviews the theoretical of maturity misdistribution.Also,from the perspective of cost effect and risk effect,the paper discusses the internal mechanism which the maturity misdistribution has effect on.The sixteen commercial banks are selected as the objects from 2007 to 2008.By using the HP filter method,calculating the bank's maturity misdistribution.Based on the DEA-SBM model,the non-performing loans of commercial banks were concerned,and calculated operating efficiency index of unexpected output,and using the panel econometric model,empirically studying of the impact of the maturity misdistribution on the efficiency of commercial banks.The study finds that China commercial banks have a more serious problem of maturity misdistribution,and mainly the phenomenon of liquidity surplus during the period of investigation.The maturity misdistribution in commercial banks considering unexpected outputs operating efficiency has obvious inhibitory effect,despite the fact that commercial banks through the use of 'Short deposit and Long loan' means the use of funds may reduce its operating efficiency,and this inhibition is mainly reflected in the state-owned commercial banks,the effect in non-state-owned commercial banks in the it is not significant,the robustness test using the panel Tobit model and dynamic panel models support the above conclusions?Further study's find that showing the inverted U type features significant efficiency of commercial bank operating in the process of maturity misdistribution and exist the existence of cost effect and risk effect.Therefore,from the aspect of supervision,to further promote the interest rate marketization reform on commercial banks,according to the new characteristics and the operation of international supervision and constantly improve the relevant laws and regulations and regulatory liquidity indicators system.For commercial banks,the need to constantly enhance the maturity misdistribution of management awareness,strengthen risk management and technology innovation,based on its actual situation,constructing the index system of the maturity mismatch of liquidity risk of the flexible.While realizing the self-discipline of the interbank business,we should broaden our business operations,develop credit asset securitization,issue commercial banks,financial bonds and so on.The relevant conclusions of this study will provide inspiration for the optimization of the maturity structure of the assets and liabilities of commercial banks and the improvement of their operational efficiency.
