从业务收益变化的角度,通过构建商业银行广义超越对数成本函数的面板固定效应模型及范围经济的测度方程,对中国不同类型商业银行1997~2006年的范围经济进行实证和对比分析得出:从整体上看,中国商业银行呈现范围经济效应,但中国商业银行的范围经济还没有达到最佳的状态;范围经济与商业银行中间业务及投资业务的发展有关,股份制商业银行的范围经济优于国有商业银行。
In terms of the changes of the business receipts, this paper compares and analyses the economies of scope of different Chinese commercial banks from 1997 to 2006 empirically, based on the construction of the panel data fixed effect models of the Generalized Translog Cost Function as well as the mensuration of the economies of scope of commercial banks. The results show that Chinese commercial banks have economies of scope from the overall perspective. However, the scope economies of Chinese commercial banks have not yet reached the best state; the scope economies relate to the development of the intermediate business and investment business of the commercial banks; the scope economies of the joint-stock commercial banks are better than that of the state-owned commercial banks.
