A股新闻共现网络的股票收益分析

利用新闻数据以全量公司为节点，以共同出现在新闻中为边，构建新闻共现网络，进行社区检测，探究网络和社群内外部股票间的收益率关系。

Utilizing news data, a news co-occurrence network is constructed with all companies as nodes, where edges are established when two companies co-occur in the same news report. Community detection is then performed to investigate the stock return relationships within the entire network, as well as between stocks inside and outside the detected communities.
