The Research On The China Public Bank's X-efficiency And The Respect Of Ownership Structure

Currently, the efficiency of the banking system is the key problem to the China's financial development. On the one hand, bank management and operation with high efficiency is a necessary requirement evolution in the financial system; On the other hand, the efficiency of banking system in China is an important factor of economic security. In order to improve bank efficiency, reformers processed orderly reform of financial system. China's banking competitive has improved to some extent and performance in general has greatly improved. The issue of X-efficiency of commercial bank is the cutting-edge research in this area. However, from currently available literature, the existing research has focused on empirical research perspective and theoretical research base is weak. The paper is trying to lay a solid theoretical foundation, discussing the relationship between the ownership structure and X-efficiency of commercial bank in China. Therefore, this article has some theoretical significance.First of all, the first part is the introduction of this article. It describes the research background and related literature; Then, from the perspective of the theory to research the ownership structure how to effect the bank X- efficiency Then, this paper use the frontier SFA to measure the X-efficiency of China's commercial banks. In the paper X-efficiency is decomposed into profit efficiency and loans efficiency, and X-efficiency of the different Bank properties were compared; Then, this paper examines the ownership structure of linear regression on the X-efficiency of banks; Finally, not only The content of this study and the results are summarized, but also use empirical results to put forward policy recommendations in China bank environment.Through the above study, the paper conclusion is: First, from a theoretical point of view on the ownership structure of banks X efficiency; second, all sample of banks are concerned, whether under the law of the intermediary, or the production method, in recent Years, the Bank of X efficiency are gradually rising trend, after the joint-stock reform of state-owned banks, the efficiency difference between state-owned banks and the other banks is less ; third, An Empirical validation of the ownership structure of banks X efficiency, ratio of largest shareholder was negatively correlated with bank X-efficiency, the proportion of top ten shareholders positive influence on bank X-efficiency.The innovation of this paper: first, from a theoretical point of view, the paper analysis the mechanism of the ownership structure how to influence X efficiency of the banks; Second, domestic empirical research of the bank's X efficiency, focusing on non-parametric method of DEA, few people use stochastic frontier analysis method, this paper has tried to promote in this aspect. the paper use the SFA method to measure bank's X-efficiency with data of 2004-2009; the third, the paper both use an intermediary approach, and production methods to measure the bank's X efficiency and compare to the past literature, which just choose One way, or the two methods of synthesis, rarely the same time using two methods.
