Based On SBM Model To Analysis The Efficiency Of Chinese Banking Industry

Commercial banks have an important position in capital financing.Finance can be understood as the integration of funds,and direct finance and indirect finance are its main categories.Direct finance means that the final demander of funds obtains the required funds directly from the final supplier of funds through the financial market,such as the company issuing stocks or bonds through the securities market.Indirect finance refers to the financial intermediation of financial intermediaries between the final demander and the final supplier of funds.For example,if residents save money to a commercial bank,the bank then supplies the money to the company in the form of a loan.The primary business of commercial banks in the early stages of development was to absorb short-term deposits and issue short-term commercial loans with a short-term amount,and to obtain the difference between deposit and loan interest as the main source of income.With the economic development,the competition among commercial banks has become increasingly fierce,and the business of commercial banks has continued to expand,providing a variety of other financial services functions such as information services,consulting services,cash management,provision of commercial letters of credit,bank acceptance bills,etc.,non-interest income.The proportion is growing.Efficiency is an important proposition of economic development,and it is also a practical issue that should be paid attention to in the development of China's commercial banks.In the context of internal and external problems,it is of great practical significance to explore the current level of efficiency of commercial banks and how to improve efficiency under existing conditions and seek breakthrough points for performance growth.This paper is based on the related literature at home and abroad,and we select 25 state-owned,joint-stock and local commercial Banks as the research sample,the situation of the period 2007-2016 as the research object.Considering the non-performing loans as the undesirable output,we select the deposit as the intermediate variable and use SBM model to estimate the every year's technology efficiency,pure technology efficiency and scale efficiency of Banks.And we analysis of their changes.Then we use technology efficiency as the dependent variable and choose some factors which may influence the efficiency of Banks as independent variables from the bank's own factors,banking industry factors and macroeconomic factors to build Tobit model and do regression analysis,then we can analysis the impact of various factors on bank efficiency.The research shows that :(1)The pure technical efficiency of Chiness banking industry has maintained a relatively high level,but it is difficult to reach the best efficiency frontier because of the scale efficiency.(2)The pure technical efficiency of the state-owned commercial banks in China is in the lead in the same industry,but the scale efficiency falls behind that of the joint-stock banks and the local banks.The technical efficiency and the pure technical efficiency of the local banks are not stable,and the volatility is great.(3)In terms of the factors that influence the technical efficiency of the bank,there is a significant positive correlation between the roa,loan-to-deposit ratio,financial innovation and the technical efficiency of the bank.The asset cost rate and the bad loan rate have a significant negative correlation with the technical efficiency of the bank,and the property right structure is not related to the bank technical efficiency.Industry factors and macroeconomic factors have no significant impact on technical efficiency.
