摘要

目的/目的:本文旨在实证量化新冠肺炎疫情对安曼证券交易所(ASE)上市公司造成的财务困境。本文还旨在确定大流行前和中期金融危机的最重要预测因素。背景:COVID-19大流行不仅对人类生命造成了巨大损失,也对许多企业造成了巨大损失。这为评估这一大流行病对约旦公司财务状况的影响提供了动力。方法:最初的样本包括165家公司,根据数据可用性,将其清理并减少到84家公司。研究人员在2019年和2020年两年内收集了84家公司的财务数据,以实证方式量化疫情对数据集中公司的影响。采用了两种方法。第一种方法是使用基于Altman(1968)模型的多元判别分析(MDA)来获得每个公司在调查期间的z分数。第二种方法涉及使用具有15个标准财务比率的人工神经网络(ann)开发模型,以找出预测财务困境中最重要的变量,并创建准确的财务困境预测(FDP)模型。贡献:本研究有助于更好地理解金融危机预测指标在动态和风险时期的表现。研究证实,尽管COVID-19对公司的财务健康产生了负面影响,但财务困境的主要预测因素仍然相对稳定。这表明,标准的财务困境预测指标可被视为不受外来财务和/或健康灾难的影响。研究结果:使用MDA的结果表明,与2019年相比,数据集中超过63%的公司在2020年的z得分较低。2020年,陷入困境的公司也增加了8%,约6%的公司不再健康。对于使用人工神经网络构建的模型,结果表明预测财务困境最重要的变量是资本回报率。使用受试者工作特征(ROC)图下面积测量的2019年和2020年模型的预测精度分别为87.5%和97.6%。对从业者的建议:鼓励决策者和高层管理人员关注已确定的高流动性比率,以做出深思熟虑的决策并采取先发制人的行动,以避免组织失败。对研究人员的建议:这项研究可以被视为调查新冠肺炎对企业财务状况影响的垫脚石。建议研究人员将本研究中使用的方法复制到不同的商业部门,以了解公司在不确定时期的财务动态。对社会的影响:约旦上市公司的利益相关者应该关注本研究中提出的最重要的财务困境预测因素。未来研究:未来的研究可能会集中在扩大本研究的范围,包括其他地理位置,以检查结果的普遍性。未来的研究可能还包括covid -19后的数据,以检查结果的变化。

Employing Artificial Neural Networks and Multiple Discriminant Analysis to Evaluate the Impact of the COVID-19 Pandemic on the Financial Status of Jordanian Companies
Aim/Purpose: This paper aims to empirically quantify the financial distress caused by the COVID-19 pandemic on companies listed on Amman Stock Exchange (ASE). The paper also aims to identify the most important predictors of financial distress pre- and mid-pandemic. Background: The COVID-19 pandemic has had a huge toll, not only on human lives but also on many businesses. This provided the impetus to assess the impact of the pandemic on the financial status of Jordanian companies. Methodology: The initial sample comprised 165 companies, which was cleansed and reduced to 84 companies as per data availability. Financial data pertaining to the 84 companies were collected over a two-year period, 2019 and 2020, to empirically quantify the impact of the pandemic on companies in the dataset. Two approaches were employed. The first approach involved using Multiple Discriminant Analysis (MDA) based on Altman’s (1968) model to obtain the Z-score of each company over the investigation period. The second approach involved developing models using Artificial Neural Networks (ANNs) with 15 standard financial ratios to find out the most important variables in predicting financial distress and create an accurate Financial Distress Prediction (FDP) model. Contribution: This research contributes by providing a better understanding of how financial distress predictors perform during dynamic and risky times. The research confirmed that in spite of the negative impact of COVID-19 on the financial health of companies, the main predictors of financial distress remained relatively steadfast. This indicates that standard financial distress predictors can be regarded as being impervious to extraneous financial and/or health calamities.

Future research may also include post-COVID-19 data to check for changes in results.
