Personal data security and stock crash risk: Evidence from China’s Cybersecurity Law
Using China’s Cybersecurity Law (CSL) as an exogenous shock, I examine how personal data security affects stock crash risk. I find that the stock crash risk of treatment firms (which collect personal data) significantly decreases after the CSL, and such decrease is larger when firms face greater personal data breach risk and have less transparent information environments before the CSL. Furthermore, treatment firms increase their investment in personal data protection after the CSL. Finally, enhanced personal data security increases firm value and promotes firms’ social responsibility to stakeholders. Overall, I provide evidence of the importance of data security for the digital economy from the perspective of capital market stability, which may present implications for data security policy worldwide.
期刊介绍:
The focus of the China Journal of Accounting Research is to publish theoretical and empirical research papers that use contemporary research methodologies to investigate issues about accounting, corporate finance, auditing and corporate governance in the Greater China region, countries related to the Belt and Road Initiative, and other emerging and developed markets. The Journal encourages the applications of economic and sociological theories to analyze and explain accounting issues within the legal and institutional framework, and to explore accounting issues under different capital markets accurately and succinctly. The published research articles of the Journal will enable scholars to extract relevant issues about accounting, corporate finance, auditing and corporate governance related to the capital markets and institutional environment.
