数字技术变革与企业股价崩盘风险:来自"两化融合"试点的证据

扫码查看
数字技术变革已经成为企业高质量发展的重要助力.利用"两化融合"试点这一准自然试验并以2007-2021年我国制造业上市公司为样本,本文采用多时点双重差分法考察数字技术变革对企业股价崩盘风险的影响.结果发现:1)随着"两化融合"试点大幅促进企业数字技术变革,企业未来的股价崩盘风险显著下降,这一结论进一步得到了一系列稳健性检验的支持.2)机制分析揭示,"两化融合"试点通过提升内部控制质量降低了企业未来的股价崩盘风险,在此过程中并未吸引更多的外部监督.3)当会计稳健性差、盈余激进度高、分析师跟踪少以及媒体关注度低时,"两化融合"试点降低股价崩盘风险的效应更显著,可见新兴数字技术与传统治理机制存在一定的互补作用.本研究丰富了数字经济支持上市公司治理改善的经验证据和作用路径,所得结论为推动数字治理提升上市公司质量提供了决策参考.
Transformation of digital technology and corporate stock price crash risk:Evidence from the pilot of"integration of informatization and industrialization"
In the current era of the digital economy,the transformation of digital technology has become a significant driving force for enterprises to achieve high-quality development.Tak-ing advantage of the pilot program of"integration of informatization and industrialization"as a quasi-natural experiment and using Chinese listed manufacturing companies from 2007 to 2021 as the sample,this paper empirically investigates the impact of digital technology transformation on the stock price crash risk using a staggered difference-in-differences approach.The findings are as follows:1)With the pilot program significantly promoting the digital technology transformation of enterprises,the risk of future stock price crash shows a notable decrease.This conclusion is further supported by a series of robustness tests.2)Mechanism analysis reveals that the pilot program reduces the risk of future stock price crash through improving internal control quality,but not attracting more external monitoring.3)The effects of the pilot program in reducing the risk of stock price crash are more pronounced when accounting conservatism is low,earnings ag-gressiveness is high,there is less analyst coverage,and media attention is low.These indicate the existence of complementary effects between emerging digital technologies and traditional gover-nance mechanisms.Our research enriches the empirical evidence supporting the improvement of corporate governance in the digital economy.The conclusions provide decision-making references for enhancing corporate quality through digital governance for listed companies.
