Empirical Study About Commercial Bank’s Capital Out Commercial Bank’s Capital Structures Affect On Their Efficiency

In recent years,the development of Chinese commercial banks is rapid. The growth of asset and profit is large. However,this over-reliance on deposit and lending interest rate to the rapid expansion of the traditional way to expand the size of Chinese commercial banks has led to huge capital gap,banks generally facing the "capital hard constraints" and this brings conflict. Therefore, it is necessary to study the effect of capital structure of Chinese commercial banks on the efficiency, and to reveal ways to improve the capital structure of commercial banks.This paper first discusses the mechanism of effect of capital structure of commercial banks on the efficiency of produce, namely, the capital structure of commercial banks through direct effects on the efficiency of the bank or through the influence of corporate governance structure, the governance structure of bank efficiency by impact. Then, using the DEA method on the data of China’s four major state-owned commercial banks, nine joint-stock commercial banks and twenty city commercial banks to measure the efficiency of 2009-2013. Furthermore, the sample data into the state-owned banks and joint-stock banks and city commer-cial banks, and the efficiency of the measured values as explained variables, all kinds of proxy variables of capital structure and some factors affecting efficiency of doing multiple linear regression analysis as explanatory variables, get the following conclusion:(1)for the state-owned banks and joint-stock banks,ratio of subsidiary capital and the net capital,the ratio of the top five shareholds of efficiency is significantly positive,the loan to deposit ratio, the influence of equity structure on efficiency is significantly negative;(2)to the city commercial banks, ratio of subsidiary capital and the net capital,the ratio of the capital adequacy ratio, the proportion of the first largest shareholder, ownership balance degree of influence on the efficiency is significantly positive, the proportion of top five shareholders, ownership concentration degree of influence on the efficiency is significantly negative.Finally, put forward the following suggestions according to the regression conclusion: Multi-channel expansion capital subsidiary; optimization of capital mana-ge ment.
