摘要：This paper investigates whether government suppliers behave differently in terms of imports during trade conflicts. We focus on the US-China Trade War setting and find that import from China of US government suppliers increases while that of other firms declines after the launch of the Trade War. Using both indirect and direct measurements of the firm's government connection, we find suppliers more closely connected with the government increase imports from China in a faster manner. The connection with the government also offers firms the advantage of getting approvals for tariff exclusion applications. The advantages of being government suppliers are reflected in the superior operating performance during the trade tension, but investors are not aware of such advantages until the information is reflected in earnings announcements, cumulative abnormal returns, and analyst forecast revisions. At last, as an external validity test, our main finding also holds for the US and Russia trade tension under the 2022 Russian invasion of Ukraine.
