近年来,网络互动平台作为上市公司与个人投资者的直接沟通渠道引起了学术界和业界的普遍关注,上市公司在互动平台的回复积极性能否通过影响个人投资者行为来降低股价崩盘风险?基于此,文章使用2010-2022 年"上证e互动"和"互动易"的问答样本,实证结果表明:(1)上市公司回复积极性能够显著降低股价崩盘风险,以上结论在分析师关注度低的组别更加显著;(2)相较于传统的信息含量机制,缓解投资者看跌情绪在统计意义和经济意义上都更加显著,上市公司回复积极性每提高 1 个标准差,投资者看跌情绪会下降 1.36%,而传统信息含量机制提升仅为 0.32%,说明上市公司回复积极性的"情绪疏导"作用更加显著.文章从行为金融视角给出了缓解股价崩盘风险的新机制,对促进资本市场高质量发展提供了一定的政策参考.
Impact of Active Responses on Crash Risk:Evidence from Online Interactive Platforms
In recent years,as a direct communication channel between listed companies and retail investors,online interactive platforms have attracted widespread attention from academics and the industry.Can the active responses of listed companies on interactive platforms reduce the crash risk by influencing the behavior of individual investors?Based on this,the article uses the Q&A samples of"SSE E-interaction"and"Interaction Easy"from 2010 to 2022,and the empirical results show that:(1)the active responses of listed companies can significantly reduce the crash risk and the influence is more significant in the group with lower analyst coverage;(2)compared with the traditional information mechanism,the relief of investors'bearish sentiment is more significant statistically and economically,and for every 1 standard deviation increase in the responses of listed companies,the investors'bearish sentiment will decrease by 1.36%,while the increase of the information is only 0.32%,which indicates that the"sentiment channeling"effect of listed companies'replies is more significant.The article gives a new mechanism to mitigate the crash risk from the perspective of behavioral finance,which provides a certain policy reference for promoting the high-quality development of capital market.
