| 3 | Does supplier concentration matter to investors during the COV1D-19 crisis:evidence from China?显示文摘The literature shows that investor attention to customer–supplier disclosure increases when suppliers’information arrival is anticipated.Due to the widespread of city lockdowns in China and the implementation of social distancing to control the COVID-19 pandemic,investor attention to potential disruption of the supply chain spikes,leading to a price devaluation for firms with high supplier concentration risk.We find that a higher degree of supplier concentration is related to more serious stock price declines over the short-term and medium-term windows right after the Wuhan lockdown.This result lends support to the argument that the concentration risk of suppliers is a significant consideration for China stock market investors,especially under the potential financial distress at the firm level induced by the COVID-19 crisis. | Louis T.W.Cheng Jack S.C.Poon Shaolong Tang Jacqueline Wenjie Wang | 2022 | Financial Innovation2022，8，1： | 0 |
