Corporate risk disclosure in response to heightened entry threat: Evidence from a quasi-natural experiment in China

Using the deregulation of market entry barriers in China as a quasi-natural experiment, this study examines how increased entry threats affect incumbent firms' risk disclosure. We find that firms respond by increasing their market-related risk disclosures. This effect is stronger among firms facing higher economic uncertainty, lower financial constraints, greater product market competition, and higher information transparency. Mechanism analysis shows that increased risk disclosure weakens the link between deregulation of market entry barriers and new firm entry, suggesting that such disclosures can effectively deter potential competitors. Moreover, while market reactions to market risk disclosures are neutral, they are negative for operational and financial risk disclosures. Our findings suggest that firms strategically disclose market risks to mitigate entry threats, thus enhancing their resilience and adaptability in dynamic markets.
