外资银行进入对我国银行业竞争度的影响--基于Panzar-Rosse模型的实证研究

1997~2011年这15年间我国银行业处于垄断竞争状态，市场竞争度呈现先减后增的U型变化趋势，而2008年国际金融危机后我国银行业市场竞争度下降。外资银行资产份额与市场竞争程度存在负相关关系，而机构数量与竞争度不相关，外资银行进入未能促进我国银行业的竞争，中国银行业市场逐步发展完善是市场竞争度变化的根本原因。

The Effects of Foreign Banks Entry on the Competition Degree in Banking Industry of China---Based on Empirical Research of Panzar-Rosse Model

In this paper the authors apply the Panzar-Rosse model to assess the degree of market competition in the banking industry of China between 1997 and 2011, and then analyze the relationship between foreign bank penetration and the degree of market competition empirically. The empirical results suggest that the banks China are operation under monopo-listic competition and the competition in banking industry is U-shaped curve, and the degree of competition dropped signifi-cantly after the financial crisis in 2008. The asset share of foreign banks is negatively correlated with the degree of market competition, while the number of foreign banks is not relevant to the degree of market competition, so foreign banks entry can not promote the market competition in China banking industry. Chinese banking market gradually developed is the root reason of the change of the degree of market competition.
