本文探讨了银行净息差（NIM）和非传统银行活动（NII）的决定因素。采用系统估计方法来控制 1997 年至 2004 年期间 28 个金融自由化国家的商业银行的 NIM 和 NII 之间的同时性。我们发现 1997 年至 2002 年期间 NIM 和 NII 之间存在统计上显着的负相关关系。在随后的时期（2003 年至 2004 年），NIM 和 NII 之间总体上呈正相关，但统计上不显着。银行越来越多地参与非传统活动与前一个子时期的风险调整盈利能力指标呈负相关，表明没有明显的多元化效益。然而，对于后一个子样本，非利息收入的份额与资产回报率（ROA）和股本回报率（ROE）呈正相关。
This paper examines the determinants of bank net interest margin (NIM) and non-traditional banking activities (NII). A system estimation approach is employed to control for the simultaneity between NIM and NII for commercial banks in a group of 28 financially liberalized countries during the period between 1997 and 2004. We find a statistically significant negative relationship between NIM and NII for the period between 1997 and 2002. A generally positive but statistically insignificant association between NIM and NII is found for the subsequent period (2003–2004). Banks’ increasing involvement in non-traditional activities is negatively correlated with risk-adjusted profitability measures in the former subperiod, suggesting no obvious diversification benefits. However, the share of noninterest income is positively related to the return on assets (ROA) and the return on equity (ROE) for the latter subsample.
