内容简介:This paper introduces a new method to identify economic links between firms using social media. If a firm is discussed extensively in the subforum of another firm, the two firms are considered to have explicit or implicit economic links. The suspension of the IPO of Ant Group in November 2020 is used as an exogenous shock, which is found to have a negative impact on the stock prices of firms that have social media connections (SMCs) with Ant Group. Additionally, the corporate and financial asset investments of those firms are also affected, confirming the real effects of SMCs.
