外资银行进入对我国银行绩效的影响——基于面板数据的实证分析

The Effects of Foreign Investment on the Performance of China's Banks:A Panel Analysis

运用我国银行1996-2007年的财务数据建立面板数据模型,从盈利水平、经营费用、稳健性、流动性四个方面实证分析入世后外资银行进入对我国银行的影响,通过统计入世前后我国银行绩效数据来说明其变化趋势的特点。研究结果表明:外资银行进入对我国银行盈利水平产生正面影响,对经营费用产生负面影响,对稳健性和流动性的影响不显著。入世前后我国银行绩效变化趋势特点:盈利水平变化趋势总体呈U曲线,最低点出现在2002年前后(即入世前后);经营费用变化整体呈下降趋势,2002年前后有明显的向下跳跃;流动性和稳健性的变化趋势不明显。

The paper first builds a panel model employing the financial data of China＇ s banks between 1996 and 2007 to analyze the effects of the entry of foreign banks on the performance of domestic banks in terms of net interest margin, operation cost, stability and liquidity. We then compare the results with data before and after China joined the WTO to trace the trend. It is found that the entry of foreign banks is significantly positively related to net interest margin but negatively related to operation cost. It bears no significant impact on the stability and the liquidity indicators. The changes in the performance of China＇ s banks are as follows. First, the net interest margin assumes a U-curve, the lowest point being around 2002. Second, the operation cost has assumed a generally declining trend throughout the study period, with a plunge around 2002. Third, no clear trend could be detected for changes in stability and liquidity.
