摘要

银行是对实现发展目标至关重要的金融机构,因为它们将资金从盈余方转移到赤字方。本研究采用 DEA 和 CAMEL 框架,对 2015 年至 2020 年埃塞俄比亚商业银行的竞争、生存和绩效制约因素进行了研究。研究采用了非参数(DEA)方法来估算被研究银行的整体技术效率得分。实证研究使用了在埃塞俄比亚运营的 12 家私营商业银行,其中不包括四家银行,因为它们缺乏适当的经审计的财务数据,也没有在研究期间进行风险评估。研究结果显示,在 CRS 下,除 Abyssinia、Anbesa 和 Nib 国际银行外,其余银行的效率较高。在 VRS 下,虽然 Abyssinia 银行的效率较低,但其他银行的效率较高。在规模效率下,Abyssinia 银行、Anbesa 银行和 Nib 国际银行的效率较低,而其他银行的效率较高。CAMEL 框架的综合排名显示,阿瓦士国际银行、泽门银行和韦加根银行排名前三,而奥罗莫合作银行、大申银行和阿比西尼亚银行排名垫底。回归结果表明,资本总额与资产总额的比率、贷款与资产的比率、贷款总额与存款总额的比率以及资本充足率对银行盈利能力有积极影响,而贷款总额与分支机构数量的比率对资产回报率有显著的负面影响。

Competition, Survival Issue, and Performance Constraints of Banks: Evidence from Ethiopian Private Commercial Banks
Banks are financial institutions that are crucial to the accomplishment of development objectives because they transfer money from surplus to deficit parties. This study examines the competition, survival, and performance constraints of commercial banks in Ethiopia using the DEA and CAMEL frameworks from 2015 to 2020. The nonparametric (DEA) approach was applied to approximate the overall technical efficiency score of the banks under consideration. The empirical study used twelve private commercial banks operating in Ethiopia, excluding four banks because of a lack of appropriate and audited financial data and no risk assessment between the study periods. The result of the study reveals that under CRS, except for Abyssinia, Anbesa, and Nib International Banks, the remaining banks are more efficient. Under VRS, while Abyssinia Bank was less efficient, other banks were found to be more efficient. Under scale efficiency, Abyssinia, Anbesa, and Nib International Banks were found to be less efficient, while the remaining banks were more efficient. The composite ranking of the CAMEL framework portrays that Awash International Bank, Zemen, and Wegagen Banks were found in the top three ranks, while Cooperative Bank of Oromia, Dashen, and Abyssinia Banks were found in the bottom position. The regression result demonstrates that the ratios of total capital to total assets, loans to assets, total loans to total deposits, and CAR have a positive effect on bank profitability, whereas the ratio of total loans to the number of branches has a statistically negative and significant influence on the return on assets.

期刊介绍: The main objective of Discrete Dynamics in Nature and Society is to foster links between basic and applied research relating to discrete dynamics of complex systems encountered in the natural and social sciences. The journal intends to stimulate publications directed to the analyses of computer generated solutions and chaotic in particular, correctness of numerical procedures, chaos synchronization and control, discrete optimization methods among other related topics. The journal provides a channel of communication between scientists and practitioners working in the field of complex systems analysis and will stimulate the development and use of discrete dynamical approach.
