中国商业银行范围经济状态实证研究

An Empirical Study of Economies of Scope of China's Commercial Banks

范围经济是金融业混业经营的前提条件。利用中国商业银行 1 994- 1 999年的经营情况进行实证分析结论可以发现 ,中国金融业的运营中同时存在着范围经济和范围不经济的现象。并且 ,范围经济系数与银行资产规模呈正相关关系 ,规模较大的银行在扩大经营范围时更容易获得范围收益。

Economies of scope are the precondition of financial mixed operation. In this paper economies of scope of the Chinese commercial banks are measured. The study employs a translog cost function and the Box-Cox transformation. Overall, economies of scope are reported for state-owned commercial banks, and diseconomies of scope are reported for most joint-equity commercial banks. The results indicate that there exists the positive correlation between economies of scope and the scale of banks.
