摘要

企业财务困境预测是经济发展的一个关键方面。预测公司将陷入财务困境的能力对于决策者、股东和决策者做出可持续发展的最佳决策和政策至关重要。预测的准确性在实施缓解痛苦措施方面至关重要,这是吸引投资的一个关键组成部分,尤其是吸引非洲大多数发展中国家的投资。第四次工业革命的到来使人工智能(AI)成为金融风险建模的中心舞台。然而,这种增长并没有排除传统统计方法在金融风险建模中的作用。学术界和从业者对这两组方法在遇险预测中的准确性缺乏共识。传统学派的倡导者仍然坚持认为统计方法更准确,而新时代的支持者则认为人工智能带来了更高水平的预测强度和模型准确性。本研究旨在比较Logit和人工神经网络在企业困境预测中的准确性。这两种建模技术被应用于津巴布韦证券交易所的一个8年面板数据集。Logit模型的总体准确率优于人工神经网络92.21%,而人工神经网络的准确率为85.8%。提高预测准确率势必会通过加强新兴市场的财务风险管理来提高股东回报。这项研究还试图为正在进行的关于人工智能技术和统计技术之间优越性的辩论做出贡献。

On logit and artificial neural networks in corporate distress modelling for Zimbabwe listed corporates

Corporate financial distress prediction is a pivotal aspect of economic development. The ability to foretell that a company will be getting into financial distress is essential for decision-makers, shareholders, and policymakers in making the best decisions and policies for sustainable development. Prediction accuracy is of paramount importance in the implementation of distress mitigation measures, a critical component attracting investment in particular to most of the developing countries in Africa. The advent of the fourth industrial revolution saw Artificial Intelligence (AI) taking centre stage in financial risk modelling. This growth has however not precluded the role of traditional statistical methods in modelling financial risk. There is a lack of consensus amongst academia and practitioners on the accuracy of these two groups of methodologies in distress prediction. Protagonists of the conventional school of thought still hold on to statistical methods being more accurate whilst the new age proponents believe AI has brought in higher levels of predictive strength and model accuracy. This study seeks to compare the accuracy of Logit and Artificial Neural Networks (ANN) in corporate distress prediction. The two modelling techniques were applied to an 8-year panel dataset from the Zimbabwe Stock Exchange. The Logit model outperformed the ANN by an overall accuracy of 92.21% compared to ANN with 85.8%. Heightened prediction accuracy is bound to improve the return to shareholders by enhancing financial risk management within emerging markets. This study also seeks to contribute to the ongoing debate on the superiority between AI techniques and statistical techniques.
