银行监管降低了银行效率吗?

Does Bank Regulation and Supervision Reduce Bank Efficiency?

基于121个国家(地区)的1024家银行的微观数据,利用世界银行专题调查数据库定量测度银行监管变量,对银行监管与银行效率之间关系进行了实证分析。研究发现:在采取更严格资本要求和有着更强政府监管权力的国家,银行资源配置能力更佳,资本监管和政府监管权力的提升有利于银行效率增加。而在对银行经营活动有着更加严格限制和对银行向市场披露信息有着更加严格要求的国家,银行效率往往更低,经营限制和市场监督显著地降低了银行效率。当控制了政治制度、法制环境和政府治理等国家制度质量差别之后,上述研究结果并没有发生改变,研究结论较为稳健。

Based on micro data of 1024 banks of 121 countries, this paper uses DEA model to estimate bank efficiency and conducts empirical research on the relationship be- tween bank supervision and bank efficiency. Our research shows：in countries with stricter capital requirement and stronger governmental supervision power, banking efficiency is high- er, that is to say, capital supervision and governmental supervision power is conducive to im- prove bank efficiency. In countries with stricter restrictions on operating activities of banks and stricter demands on disclosure of information of banks to market, banking efficiency is usually lower, as operating restrictions and market supervision significantly decline bank ef- ficiency. When the variables of political system, legal environment, governmental rule by law and other state systems＇ quality difference are controlled, the above research results remain, which indicates that our research conclusions are robust.
