The effect of financial sector development on economic growth is among the main debatable issue in economics and policymaking. Thus, by using different financial sector dimensions, this research tried to look at the effect of financial sector development on the economic growth of 25 sub-Saharan Africa countries for the period 2010–2017. Precisely, three dynamic panel data models that look at the effect of financial sector depth, access, and efficiency on economic growth were estimated by two-step system GMM estimation. In this research, credit extended to the private sector per GDP, commercial bank branch per 100,000 adult population, and Return to assets were used as a proxy and measures for financial sector depth, access, and efficiency respectively. Accordingly, the results revealed that financial sector depth, access, and efficiency have a positive and statistically significant effect on these countries' economic growth. Therefore, it is recommended that the concerned bodies that broadening the depth of financial institutions by giving more credit to the private sector is essential. Besides, the financial institutions will have to be expanded to increase their accessibility to the mass and take some measures to promote their efficiency.

金融部门发展对部分撒哈拉以南非洲国家经济增长的影响

金融部门发展对经济增长的影响是经济学和政策制定中的主要争议问题之一。因此，本研究通过使用不同的金融部门维度，试图考察2010-2017年期间金融部门发展对25个撒哈拉以南非洲国家经济增长的影响。准确地说，通过两步系统 GMM 估计来估计三个动态面板数据模型，这些模型着眼于金融部门深度、准入和效率对经济增长的影响。在这项研究中，每 GDP 向私营部门提供的信贷、每 10 万成年人口的商业银行分支机构和资产回报率分别用作金融部门深度、准入和效率的代理和衡量标准。因此，结果显示，金融部门的深度、准入、和效率对这些国家的经济增长具有统计上显着的积极影响。因此，建议有关机构通过向私营部门提供更多信贷来扩大金融机构的深度至关重要。此外，必须扩大金融机构的规模，以提高其对大众的可及性，并采取一些措施提高其效率。
