我国商业银行效率的影响因素:产权制度还是市场结构

采用自由分布法(DFA),利用似不相关回归估计测算了我国商业银行的X-成本效率状况,并分析了产权制度与市场竞争程度对我国商业银行效率的影响。实证检验发现,我国国有银行和股份制银行的X-成本效率存在结构性差别,产权制度是造成这种差异的关键原因,市场竞争程度对银行效率也产生了非常重要的影响;且两者对银行效率的影响是一种互补关系而不是替代关系。可供选择的政策建议包括:推进产权制度改革,完善银行的法人治理结构;优化银行业市场结构,促进银行体系效率的提高;国有银行要适当收缩规模,正确配置资源;股份制银行要尽快充实资本金,扩大规模,增强竞争力。

On the Efficiency of Chinese Commercial Banks: Ownership or Market Structure

Based on the Distribution Free Approach(DFA),this paper estimates the status of X-cost efficiency through the Seemingly Unrelated Regression,and analyzes the property rights institutions and the market competition's influencing on the cost efficiency.The results of the empirical study show that there are institutional differences between the X-profit efficiency of the state-owned banks and that of the joint-stock banks,and the key factor that contributes to those differences is the property rights institutions;and market structure also have an important influence on the efficiency,Then,how each of the factors affects the efficiency of Chinese commercial banks is analyzed,and related ways to improve the status are suggested.
