With China’s economy entering the new normal,the growth rate of the economy changes from the original high-speed growth to the medium high-speed growth,the industrial structure is further optimized and adjusted,the banking industry is also facing challenges,and the profitability of the bank is reduced,which has become the "new normal" of the banking industry.In the past,the double-digit high growth has become the past style.In the past,unreasonable credit supply made the balance of non-performing loans increase year by year,the pressure on asset quality continues to expand,and the risk of default continues to accumulate,threatening the stable operation of the financial system.Centralized or decentralized allocation of credit funds is a dilemma for listed banks.To some extent,the allocation of credit funds affects the asset quality of banks.Especially when the banking industry has entered the "new normal" non-performing loans often occur,which will affect the asset quality of commercial banks.Credit investment direction will be divided into two perspectives: one is to consider the impact of concentration on bank asset quality from the perspective of industry,the other is to consider from the perspective of customer concentration.If the concentration of bank credit tends to several major industries,once the economy is in a downward stage,the non-performing assets of banks will increase dramatically,and the non-performing loan rate will rise,then the asset quality of banks will deteriorate dramatically.Listed bank credit focuses on big customers,which are often highly qualified or even guaranteed by the government,which will greatly reduce the bank’s non-performing loans.It can be seen that the concentration of bank credit and how to allocate credit resources have an important impact on the asset quality of banks.This paper is divided into five parts,the introduction part mainly introduces the research background and significance,domestic and foreign research review,research content and methods.In addition,it summarizes the limitations of the research content,and puts forward the prospects for the future research direction: the first chapter mainly introduces the concept of credit concentration,the measurement method of credit concentration and the mechanism of the impact of credit concentration on the asset quality of listed banks in China;the second chapter mainly analyzes the formation of thephenomenon of loan concentration of listed banks in China from the macro and micro levels The reasons are as follows: information asymmetry,economic development policy adjustment,etc.Finally,based on the semiannual report data of 16 listed banks in China,this paper analyzes the loan and credit investment direction of listed banks in China,mainly analyzes the current situation of industry and customer credit concentration.The third chapter is the core part of the paper.It describes the explained variables,explained variables and control variables proposed in the hypothesis,establishes the panel data model,takes the loan concentration degree of two angles as the explanatory variables,and controls the loan scale,provision coverage rate,deposit loan ratio variables.This paper studies the impact of loan concentration on the asset quality of listed banks in China.Finally,the research results are discussed and analyzed,and corresponding research suggestions are put forward for different problems.In this paper,the fixed effect model is used to study the relationship between credit concentration and bank asset quality.In this paper,16 A-share listed banks in China are selected for research,and the data is selected from the semi-annual data from 2007 to 2018.The main conclusions are as follows:(1)the increase of industry cumulative concentration will reduce the asset quality of listed banks,and the increase of customer cumulative concentration will improve the asset quality of listed banks.(2)in the economic upward cycle,for large state-owned banks,the positive impact of industry concentration on the asset quality of banks has been significantly strengthened.However,the difference of business cycle and ownership nature of commercial banks does not affect the impact of customer concentration on the quality of bank assets. |
