本文以2010—2021年沪深A股为样本,实证发现数字化转型言行差距会显著提高股价崩盘风险,并揭示经济政策不确定性感知及企业亏损的作用。

摘要:

企业在数字化转型中“丰满”的承诺与“骨感”的绩效之间的反差,可能导致更高的股价崩盘风险。本文选取2010年至2021年沪深A股上市公司为样本,实证分析数字化转型中言行差距(GDT)对股价崩盘风险的具体影响,并探讨GDT的可能成因。研究发现,GDT显著提高股价崩盘风险,且经过一系列稳健性检验后,该结论依然成立。在进一步研究中,对GDT成因的更深入考察表明,企业对经济政策不确定性的感知会显著增加GDT,且这一效应在亏损企业样本中更为明显。同时,异质性检验结果显示,当国有企业处于GDT情形时,投资者对其更为宽容。综上,本文在数字化转型的两种衡量方式——数字文本频率与数字技术份额——之间搭建了具体桥梁,并为增强资本市场稳定性提供了新的见解。

英文摘要:

The contrast between companies' "fleshy" promises and the "skeletal" performance in digital transformation may lead to a higher risk of stock price crash. This paper selects a sample of Shanghai and Shenzhen A-share listed companies from 2010 to 2021, empirically analyses the specific impact of the gap between words and deeds in digital transformation (GDT) on the stock price crash risk, and explores the possible causes of GDT. We found that GDT significantly increases the stock price crash risk, and this finding is still valid after a series of robustness tests. In a further study, a deeper examination of the causes of GDT reveals that firms' perceptions of economic policy uncertainty significantly increase GDT, and the effect is more pronounced in the sample of loss-making firms. At the same time, the results of the heterogeneity test suggest that investors are more tolerant of state-owned enterprises when they are in the GDT situation. Taken together, we provide a concrete bridge between the two measures of digital transformation - digital text frequency and digital technology share - and offer new insights to enhance capital market stability.
