Does mandatory real-name identification improve the informativeness of social media? Evidence from a Quasi-natural experiment in China
The impact of real name versus anonymity on social media represents a contentious issue. This study leverages a natural experiment in China and uses social media data from financial markets to investigate the impact of mandatory real-name identification on the informativeness of social media. We find a decrease in the informativeness of social media after the mandatory real-name identification. At the user level, our tests show that mandatory real-name identification primarily diminishes the informativeness of postings generated by high-follower users, who wield considerable influence in the capital market. Moreover, after the mandatory real-name identification, the percentage of postings with valuable information decreased and the language style became more ambiguous and lacked opinions. These findings align with the idea that the consequences of mandatory real-name identification predominantly arise from an increased perception of regulatory risk among users. Overall, this study contributes significantly to the comprehension of how anonymity influences the informativeness of social media.

Chilling Hypothesis
The chilling hypothesis suggests that mandatory real-name identification increases users' perceived regulatory and litigation risks, thereby reducing their willingness to freely express opinions and share valuable information on social media. This leads to a decrease in the overall informativeness of the platform, as users self-censor sensitive or forward-looking views.
Disciplining Hypothesis
Conversely, the disciplining hypothesis posits that mandatory real-name identification could enhance social media's informativeness by enabling easier identification of users spreading false information. This reduces the prevalence of misinformation and noise, improving the quality and trustworthiness of content.
User-Level Analysis
Our user-level tests demonstrate that the negative impact of mandatory real-name identification primarily affects anonymous users and high-follower users. High-follower users, who hold significant influence, become more cautious, leading to a reduction in their informative postings. Textual analysis further shows a decrease in predictive postings, definite statements, and personal opinions.
Impact on Capital Market
The study finds that after mandatory real-name identification, the influence of social media sentiment on capital market indicators (cumulative abnormal returns, trading volume, and bid-ask spread) significantly weakens. This suggests that the valuable information previously conveyed by social media postings is no longer as rapidly or effectively incorporated into stock prices, confirming a diminished informativeness.

Disproportionate Impact on High-Follower Users
Our analysis reveals that the negative impact on social media informativeness is predominantly driven by users with a substantial number of followers. These influential users, who wield considerable power in the capital market, become more cautious and reduce their valuable postings due to increased regulatory scrutiny after mandatory real-name identification. This suggests that the perceived regulatory risk disproportionately affects those with higher visibility.
