摘要

新冠肺炎疫情给各国经济带来剧烈波动。与此同时,政府拯救经济的能力取决于银行如何向陷入困境的公司提供信贷。因此,疫情对银行信贷和普惠金融的影响值得探讨。然而,现有的研究大多集中在金融经济体制改革上,只注重理论机制分析和效果调整,数据支持不足,方案落地不足。同时,随着近年来人工智能技术的兴起和快速发展,各行各业都将其引入到真实场景中,用于多源异构大数据分析和决策辅助。因此,本文首先以中国大陆为例。通过研究疫情对银行信贷偏好的影响和普惠金融的机制,可以为后疫情时代的金融体系更好地将信贷资金流向各主体提供客观决策依据,并为相关研究形成新的视角。然后,我们提出了一个基于双向长短期记忆网络(BiLSTM)和注意机制的模型来预测COVID-19大流行期间每天的新诊断病例数。它不仅适用于具有时间序列和非线性特征的COVID-19大流行数据,而且通过引入注意机制,可以自适应地选择最相关的输入数据,解决了计算量大、预测结果不准确的问题。最后,通过实验和实证研究,我们得出以下结论:(1)新冠疫情的影响将促进企业增加信贷。(2)银行向大型企业提供更多信贷。(3)疫情对不同地区信贷的影响不同,中部地区影响最大。(4)疫情下银行倾向于向制造业提供更多信贷。(5)数字普惠金融对新冠肺炎疫情期间银行信贷发挥(正向)调节作用。受研究结果的启发,政策制定者可以考虑进一步解决信息不对称,加强信用体系建设,对企业采取更直接的金融支持政策。(6)采用基于BiLSTM-Attention网络的COVID-19预测模型准确预测COVID-19大流行疫情,可为制定疫情防控政策提供重要依据。

COVID-19 Forecast and Bank Credit Decision Model Based on BiLSTM-Attention Network
Abstract The COVID-19 pandemic has caused drastic fluctuations in the economies of various countries. Meanwhile, the governments’ ability to save the economy depends on how banks provide credit to troubled companies. Therefore, the impact of the epidemic on bank credit and inclusive finance are worth exploring. However, most of the existing studies focus on the reform of the financial and economic system, only paying attention to the theoretical mechanism analysis and effect adjustment, scant data support, and insufficient scheme landing. At the same time, with the rise and rapid development of artificial intelligence technology in recent years, all walks of life have introduced it into real scenes for multi-source heterogeneous big data analysis and decision-making assistance. Therefore, we first take the Chinese mainland as an example in this paper. By studying the impact of the epidemic on bank credit preference and the mechanism of inclusive finance, we can provide objective decision-making basis for the financial system in the post-epidemic era to better flow credit funds into various entities and form a new perspective for related research. Then, we put forward a model based on Bi-directional Long Short-term Memory Network (BiLSTM) and Attention Mechanism to predict the number of newly diagnosed cases during the COVID-19 pandemic every day. It is not only suitable for COVID-19 pandemic data characterized by time series and nonlinearity, but also can adaptively select the most relevant input data by introducing an Attention Mechanism, which can solve the problems of huge calculation and inaccurate prediction results. Finally, through experiments and empirical research, we draw the following conclusions: (1) The impact of the COVID-19 pandemic will promote enterprises to increase credit. (2) Banks provide more credit to large enterprises. (3) The epidemic has different impacts on credit in different regions, with the most significant one on central China. (4) Banks tend to provide more credit to manufacturing industries under the epidemic. (5) Digital inclusive finance plays a (positive) regulating effect on bank credit in COVID-19 pandemic. Inspired by the research results, policymakers can consider further solving the information asymmetry and strengthening the construction of a credit system, and more direct financial support policies for enterprises should be adopted. (6) By adopting the COVID-19 prediction model based on the BiLSTM-Attention network to accurately predict the epidemic situation in the COVID-19 pandemic, it can provide an important basis for the formulation of epidemic prevention and control policies.
