The Research on the Influence of Digital Attention on Investor Behavior
Authored by: Jia Tang, Biyu Guan
This study examines the stage-based effects of digital attention on market trading activity in China's artificial intelligence (AI) sector. Daily data from November 2022 to October 2025 are used, including the Baidu Search Index (Search), the Baidu News Index (News), and the daily trading volume of the AI stock index (Volume). A multi-level empirical framework was constructed to analyze how different forms of attention influenced market activity across distinct phases. The results show that search attention consistently has a significant positive effect on trading volume and that its impact is strongest during the hype phase when technical discussions are most active. News attention exerts a weaker influence and contributes to trading activity mainly during the rational transition phase. The effects of attention display clear stage-based heterogeneity, reflecting a shift from hype-driven trading to more rational and stable mar-ket behavior. These findings provide empirical evidence on the dynamic relationship between technological attention and market actions, deepen the understanding of how emerging technologies diffuse and generate economic consequences, and offer useful impli-cations for regulators and investors in risk monitoring and market assessment.

Integrating Theories of Attention and Innovation
This research ingeniously combines Kahneman's Limited Attention Theory with Gartner's Technology Hype Cycle. This framework explains how attention, a scarce cognitive resource, dynamically influences investor behavior as new technologies (like AI) evolve through distinct phases: from initial hype, through diffusion, to eventual integration and stabilization. This provides a robust lens for understanding market reactions beyond linear models.
Discerning Active Search vs. Passive News Influence
We differentiate between two critical forms of digital attention: active search (proxied by Baidu Search Index) and passive reception (proxied by Baidu News Index). The study reveals that active search consistently drives trading activity, especially during early hype, reflecting proactive investor interest. Passive news reception, while influential, often plays a more complementary role, shaping sentiment rather than directly initiating trading in initial phases.
Unpacking Stage-Based Dynamics in Investor Behavior
The analysis unveils a clear "frenzy-to-rationality" evolution in AI market behavior. During the initial "Frenzy Period" (Stage 1), search-driven effects are strongest. This transitions to "Transitional Rationality" (Stage 2) where search impact weakens and news gains relevance. Finally, in the "Rational Stabilization" phase (Stage 3), both active and passive attention integrate, signifying a more mature market. This aligns precisely with the Technology Hype Cycle's predicted trajectory.

Regulating AI Market Volatility with Digital Attention
Regulators can leverage digital attention indices, such as the Baidu Search Index, to identify sentiment peaks and warn of excessive trading during early hype phases of emerging technologies like AI. For example, a sharp surge in active search for 'Artificial Intelligence' combined with high volatility might trigger an alert for potential speculative bubbles, guiding timely policy interventions to mitigate market risks and promote stable development.
