摘要:

本文通过分析公司股票价格对新冠疫情冲击的反应,研究了公司现金、库存和社会责任得分在疫情冲击中对稳定公司股票价格的作用,并比较了资产市值-账面比、规模、杠杆率和资产周转率等其他公司特征的影响。研究结果表明,现金、社会责任和资产市值-账面比对公司具有较大的显著为正的价值效应,而公司库存不存在正的价值效应。在疫情前持有现金、社会责任得分或资产市值-账面比越高的公司,对缓解公司股票价格下跌和稳定公司股票波动率上升的作用越大;当公司位于受疫情影响较严重省份或属于疫情影响严重的行业时,其现金和社会责任得分对稳定公司权益价值的作用更显著;随着市场流动性增加或者公司融资约束降低,公司的库存水平才开始显现正的价值效应,对减缓公司股票价格下跌起作用。本文的研究结果对公司如何进行危机预防性管理具有一定的参考价值,也在一定程度上加深了公司对社会责任的理解,有利于鼓励公司更好地参与社会责任活动。

Abstract:

The emergency of COVID-19 epidemic causes the fast dropping of GDP and prevents the development of world economics. Most of companies emerge the large loss, and even lots of companies had gone bankrupt during covid-19 epidemic. For corporate finance respective, the question attracts our attention: which corporate characteristics and what mechanisms can help the companies to alleviate the shocks of COVID-19 epidemic. It attempts to reveal the value effects of corporate characteristics such as cash, inventory and social responsibility in this paper. By analyzing the response of company stock prices to the impact of COVID-19, it focus on the role of corporate cash, inventory and social responsibility scores in stabilizing company stock prices under the shock of the epidemic, and the effects of other corporate characteristics are compared such as market to book ratio, size, leverage ratio and asset turnover ratio.RETit=α+β1INVTi×COVIDt+β2CASHi×COVIDt+β3LnCSRi×COVIDt+β4COVIDt+β5INVTi+β6CASHi+β7LnCSRi+φ'Xi+IFE+PFE+FFE+εit.Where is the return rate of stock, and the cross-term INVTi×COVIDt?CASHi×COVIDt and LnCSRi×COVIDt are the union impacts of corporate cash, inventory, social responsibility and COVID-19 epidemic.To check the impacts of corporate cash, inventory and social responsibility on the company equity return during the COVID-19 epidemic, the following regression equation is used. The daily return rates from Jan. to April 2020 of stocks from 1470 firms of A-share market are used, which is not include into ST firms, financial corporates, housing and other public management corporates. There are 116,507 daily return rates. To test efficiently the impacts of corporate characteristics on the shocks of COVID-19 epidemic and avoid the Endogenous problem in the regression, all data of corporate characteristics are chosen at the end of 2019, before COVID-19 epidemic.All data is from CSMAR database.Our empirical results show that cash, social responsibility and market to book ratio have significant positive value effects, while corporate inventory has not that effect. The higher the companies holding cash, social responsibility score or market to book ratio before the epidemic, the greater the effect on alleviating the decline of stock price and stabilizing the rise of stock volatility. Besides, for companies in provinces or industries with more severe epidemics, cash and social responsibility levels have more significant effects on the company's ability to stabilize the equity return. Only when the market liquidity increases or the financing constraint of the company decreases, the inventory level become to emerge a positive value effect to the decline of the stock price. This study has a certain reference value for the company how to carry out crisis prevention management, and is of great significance to encourage the company to participate in social responsibility activities and understand the value of social responsibility to the company.

Key words: the COVID-19, cash holdings, inventory, social responsibility
