摘　　要：随着互联网金融的不断发展,研究财经平台的发帖行为对股价涨跌的影响效应具有现实意义。本文以东方财富网股吧中的互联网金融上市公司的发帖行为为基础,使用2022年1—5月的股票相关数据研究股评数及股评情绪对股价涨跌的影响。研究发现:个人投资者情绪的高涨会使股价上涨,个人投资者情绪增加一个单位使股价上涨的胜算提高了24.69%;而个人投资者的关注度增加会使股价下跌,个人投资者关注度每增加1个单位使股价上涨的胜算降低了46.74%。发帖行为对股价涨跌的影响研究为个人投资者做出更合理的决策、互联网金融行业的发展及股市的平稳发展提供借鉴。With the continuous developmcnt of Internet finance,it is of great significance to study the effect of Posting behavior of financial platforms on stock price trend.Based on the Posting behavior of listed Internet financial companies in Oriental Fortune Stock Bar,this paper uses stock related data from January to May 2022 to study the number of share comments issued and the impact of share comment sentiment on stock price rise and fall.The rising investor sentiment will make the stock price rise,each additional unit increases the probability of the stock price rise by 24.69%.However,when investors pay more attention,stock prices fall.An increase in investor attention by one unit reduces the odds of a stock price rising by 46.74%.The research on the influence of Posting behavior on stock price can provide reference for investors to make more favorable decisions,the development of Internet finance industry and the stable development of stock market.
