Abstract

Traditional risk measurements have proven inadequate in capturing tail risk and nonlinear correlation. This study proposes a novel approach to measure financial risk in the Internet finance industry: a new Value-at-Risk (VaR) measurement based on quantile regression neural network (QRNN). Sparrow Search Algorithm (SSA) is utilized to optimize the QRNN model, which improves the model's performance in predicting internet finance risk. By comparing the TGARCH-VaR and QR-VaR approaches, our study demonstrates the effectiveness of the QRNN-VaR approach and its potential to improve the accuracy of risk prediction in the Internet finance industry. This study further examines and compares the risks between the traditional and internet finance industries. It also considers the unique impact of COVID-19 on industry risk based on statistical testing for differences and machine learning models. Our results indicate that the level of risk in the Internet finance industry is higher than in the traditional finance industry. Moreover, COVID-19 has contributed to increased risk within the Internet finance industry. These findings have significant implications for investors and policymakers seeking to better understand and manage risks within the Internet finance industry, particularly in the ongoing COVID-19 pandemic.

基于分位数回归神经网络的风险价值:来自互联网金融公司的新证据
传统的风险度量在捕捉尾部风险和非线性相关性方面已被证明是不够的。本文提出了一种衡量互联网金融行业金融风险的新方法:基于分位数回归神经网络(QRNN)的价值-风险(VaR)衡量方法。利用麻雀搜索算法(SSA)对QRNN模型进行优化,提高了模型预测互联网金融风险的性能。通过比较TGARCH - VaR和QR - VaR方法,我们的研究证明了QRNN - VaR方法的有效性及其在提高互联网金融行业风险预测准确性方面的潜力。本研究进一步考察和比较了传统金融和互联网金融行业的风险。它还考虑了基于差异统计测试和机器学习模型的COVID - 19对行业风险的独特影响。研究结果表明,互联网金融行业的风险水平高于传统金融行业。此外,COVID - 19加剧了互联网金融行业的风险。这些发现对寻求更好地了解和管理互联网金融行业风险的投资者和政策制定者具有重要意义,特别是在正在进行的COVID - 19大流行中。

期刊介绍: ASMBI - Applied Stochastic Models in Business and Industry (formerly Applied Stochastic Models and Data Analysis) was first published in 1985, publishing contributions in the interface between stochastic modelling, data analysis and their applications in business, finance, insurance, management and production. In 2007 ASMBI became the official journal of the International Society for Business and Industrial Statistics (www.isbis.org). The main objective is to publish papers, both technical and practical, presenting new results which solve real-life problems or have great potential in doing so. Mathematical rigour, innovative stochastic modelling and sound applications are the key ingredients of papers to be published, after a very selective review process. The journal is very open to new ideas, like Data Science and Big Data stemming from problems in business and industry or uncertainty quantification in engineering, as well as more traditional ones, like reliability, quality control, design of experiments, managerial processes, supply chains and inventories, insurance, econometrics, financial modelling (provided the papers are related to real problems). The journal is interested also in papers addressing the effects of business and industrial decisions on the environment, healthcare, social life. State-of-the art computational methods are very welcome as well, when combined with sound applications and innovative models.
