基于三階段DEA模型的上市銀行X-效率研究
[Abstract]:The large scale of assets of listed banks is the backbone of China's banking industry, and its operational efficiency has an important impact on the whole banking industry. X-efficiency is a measure of the level of enterprise management. It is of great significance to measure the X-efficiency of listed banks. In this paper, X-efficiency refers to the synthesis of all technical efficiency and allocation efficiency except economies of scale and economies of scope. Therefore, this paper first measures the allocation efficiency and pure technical efficiency of listed banks. Then the pure management efficiency is obtained by adjusting the environmental variables and statistical errors to the pure technical efficiency, and the final X-efficiency of the listed bank is obtained. This paper uses three ways to measure the x-efficiency of listed banks. The first is based on the input-oriented model to measure the efficiency of listed banks each year, secondly, the same bank in different years is regarded as different decision-making unit, and the efficiency value is measured based on the same efficiency frontier. Finally, based on the output-oriented model, in the second stage of the three-stage DEA model, the output items of listed banks are adjusted according to environmental variables and statistical errors. The comparison of the x-efficiency of the three ways shows that the X-efficiency of the listed bank can be accurately reflected by the correlation coefficient between the measurement value of the third way and the per capita profit of the bank, and the correlation coefficient of the per capita loan is higher than that of the other three modes. The measurement results show that the cost efficiency, allocation efficiency, technical efficiency and X-efficiency of listed banks in China are on the rise as a whole. Among the three kinds of listed banks: joint-stock commercial banks, state-owned banks and city commercial banks, the allocation efficiency and x-efficiency of urban commercial banks are relatively high, and the cost efficiency and technical efficiency of joint-stock commercial banks are relatively high. The differences among the three types of banks have gradually narrowed. The external environment, such as market share and policy environment, has a differential effect on the listed banks, and the length of the listed years of the banks has no significant effect on the efficiency of the banks. Based on the x-efficiency measurement value of listed banks, this paper tries to find out the influencing factors of X-efficiency from the perspective of bank governance, human resources and technological innovation. The results of empirical analysis show that the X-efficiency of listed banks has a significant positive correlation with the quality of human resources of banks, and the correlation between X-efficiency and management compensation is not significant and very small. Therefore, listed banks should attach importance to the level of staff quality. Perfect the incentive mechanism of enterprise management. The X-efficiency ratio of listed banks is negatively correlated with the ratio of compensation gap within the enterprise, and the proportion of the first largest shareholder is negatively correlated, which indicates that the greater pay gap has a certain impact on the level of employees' work effort. The proportion of the largest shareholders is too high to the listed banks have a certain adverse impact. The X-efficiency value of listed banks has a significant negative correlation with the ratio of non-interest income of banks, or because of the long-term credit-based income model in China's banking industry.
