Yoshiro等（2005）发现，日本商业银行的有效结构假设是成立的。他们使用了1974年到2001年的数据，为日本的所有主要商业银行。相反，Mensi和Zouari（2010）得出的结论是，有效结构假设对于突尼斯银行体系并不适用。他们通过X效率，分配效率，规模效率等多种方法来验证模型。同样的研究也拒绝了SCP假设。 Jeon和Miller（2005）认为高效结构假设对于美国银行体系并不成立，但市场力量的假设是成立的。

Smirlock（1985）指出，他的论文中分析的单位国有银行的高效结构假设是正确的。他发现，市场份额如果在数据中得到很好的解释，就会把银行市场集中度作为一个独立的变量无用。然而，市场份额作为自变量解释了银行的盈利能力较好。然而，Goldberg和Rai（1996）却表明，银行市场集中度和盈利能力之间没有统计上的显着关系。在他们的模型中，他们应用了一种更为稳健的效率方法，而不是在模型中没有直接使用效率度量的旧研究。

Yoshiro et al (2005) found that the efficient structure hypothesis holds for the Japanese commercial banks. They used the data for 1974 to 2001 for all the major commercial banks in Japan. On the contrary, Mensi and Zouari (2010) arrived at the conclusion that the efficient structure hypothesis does not hold true for the Tunisian banking system. They validate their models through several approaches of efficiencies like X-efficiency, Allocative Efficiency, and Scale Efficiency etc. The same study also rejects the SCP hypothesis. Jeon and Miller (2005) determined that efficient structure hypothesis does not hold for the US banking system as well but the hypothesis of market power holds true.

Smirlock (1985) however pointed that efficient structure hypothesis holds true for the unit state banks which he analyses in his paper. He found that market share, if well accounted for in the data, makes the presence of market concentration of the banks as an independent variable useless. However, market share as an independent variable explains the profitability of the banks relatively well. Goldberg and Rai (1996) however showed that there is no statistically significant relation between market concentration and profitability of the bank. In their model, they apply a more robust method of efficiency as opposed to the older studies which did not specifically and directly use measures of efficiency in their models.
