我国银行市场业最优市场结构研究——基于竞争与信用风险的实证角度

Study of Optimal Structure of Banking Market in China from the Perspective of Competition and Credit Risks

利用面板数据模型和季度数据检验我国上市商业银行业市场结构和信用风险的关系,验证两者之间存在的U型关系,发现我国国有商业银行和非国有商业银行都具有竞争程度低于最优的银行业市场竞争程度,且国有行的偏离更大。文章认为我国的利率市场化对国有行的信用风险影响不显著,而对非国有上市商业银行影响显著。

By using panel data and quarterly data, this paper tests the relationship between market structure of listed commercial banks and credit risk in China, the results show the U-shape relationship between them. It is also found that the competition degrees of both state-owned and non-state-owned commercial banks are lower than that of the optimal banking market, and the deviation degree of state-owned banks is bigger. In addition, China＇s liberalization of interest rate has unobvious effect on credit risks of state-owned banks while it exerts remarkable influence on credit risks of non-state-owned listed commercial banks.
