Based　on　an　exogenous　shock-the　2008　revision　of　the　Catalog　of　Technologies　Prohibited　and　Restricted　from　Export　in　China-we　use　a　difference-in-differences　(DID)　research　design　to　examine　the　impact　of　technology　export　restrictions　(TERs)　on　corporate　trade　credit　financing.　We　document　that　TERs　limit　a　firm＇s　access　to　trade　credit.　Specifically,　TERs　reduce　corporate　trade　credit　by　approximately　44　%　compared　with　that　of　an　average　firm　in　the　sample.　Moreover,　the　negative　impact　is　more　pronounced　for　firms　with　high　financial　risk　or　high　product　risk.　Additionally,　our　tests　show　that　both　upstream　and　downstream　firms　reduce　their　provision　of　trade　credit　to　firms　impacted　by　TERs.　The　results　suggest　that　TERs　add　trade　barriers　between　countries,　resulting　in　restricted　corporate　trade　credit　financing.
