摘要
本文在对Kopecky & Vanhoose(2004b)模型分三种情形进行扩展的基础上,构建了一个双约束商业银行利润函数模型来分析不良贷款率、资本充足率和法定准备金率对商业银行效率的作用机理,然后使用我国18家商业银行2002—2013年的数据,测算出我国商业银行的成本效率、利润效率和技术效率均值,进而基于所估测的成本效率、利润效率和技术效率值,通过数值拟合对理论模型得出的有关结论进行实证检验。研究结果表明,不良贷款率与商业银行的成本效率、利润效率和技术效率成负相关,而资本充足率、法定准备金率对商业银行的成本、利润和技术效率的影响是非线性的,并且三者对商业银行效率的影响路径具有明显的差异。
From the 1990s, China＇s central government carried out a series of fruitful reforms to state-owned commercial banks, especially the implementation of the shareholding system reform at the beginning of the 21st cen- tury, this forcefully promoted the development of Chinese commercial banks. In addition, since joined in the Basel accords, China＇s government for financial sector regulation also gradually entered to guard against financial risk as the core of prudential regulation stage, so the people＇s bank of China and the China banking regulatory commission have strengthened prudential regulation to the non-performing loans, capital adequacy and risk assets of commercial banks, which made the governance efficiency and risk prevention capacity of Chinese commercial banks had re- ceived a significant boost. It could be said that the commercial bank system has basically walked on the positive de- velopment orbit. At this time, a question naturally floated in our minds： whether did commercial bank reform by means of reducing non-performing loans, and improving the capital adequacy ratio significantly improved the effi- ciency of Chinese commercial Banks？ Meanwhile, how intensity did the effect of continuously improving deposit re- serve rate for commercial Banks in China since 2003 year？ Whereupon, on the basis of extending Kopecky ＆ Vanhoose （2004 b） model by dividing three kinds of situa- tions, this paper constructed a dual commercial Banks profit function model, and analyzed the endogenous influ- ence mechanism of non-performing loan ratio, capital adequacy ratio and reserve requirements to the efficiency of commercial banks. Then, it used 18 commercial banks of China related data in 2002-2013 year to measured the av- erages of cost efficiency, profit efficiency and technical efficiency of commercial banks, and found cost efficiency, profit efficiency and technical efficiency of commercial banks had presented a ascending trend in 2002-2013 year. Finally, the article, through the numerical fittin
