基于规模经济和技术进步两种效应的商业银行效率研究

The Efficiency Research of Chinese Commercial Banks:Based on the Empirical Analysis of Economies of Scale and Technological Progress

利用超对数成本函数,从规模经济和技术进步角度,对中国商业银行1995到2005年的效率进行实证表明,一方面,中国商业银行业存在着规模经济和技术进步正效应,这主要得益于股份制商业银行;另一方面,国有商业银行的规模不经济和技术进步负效应,导致中国商业银行业的效率较低。因此,要保持中国商业银行业效率的不断提高,必须压缩国有商业银行的规模,加快股份制商业银行的发展,改善商业银行的治理结构,完善金融人才的培养机制。

In this paper, an empirical analysis is given on the efficiency of Chinese commercial banks from 1995 to 2005 in two aspects of economies of scale and technological progress by making use of a muhi-product translog cost function. The results indicate that, on the one hand, joint-equity commercial banks make a greater contribution to the existence of the positive effect between the economies of scale and the technological progress for all groups in the sample; on the other hand, the negative effect between the diseeonomies of scale and the technological progress of the state-owned commercial banks results in lower efficiency of Chinese commercial banks. Therefore, in order to steadily increase the efficiency of Chinese commercial banks, the scale of state-owned commercial banks must be reduced, development of the joint equity commercial banks must be sped up, governance structure of commercial banks must be improved, and train system of financial scientists must be established.
