This　study　attempts　to　characterize　the　literature　related　to　input-output　analysis　between　1990-2017　through　bibliometric　analysis　technology　based　on　the　Science　Citation　Index　and　Social　Sciences　Citation　Index　databases.　By　means　of　bibliometric　tools,　this　paper　provides　deep　insights　on　the　patterns　of　these　articles,　the　most　influential　works　and　authors,　and　the　emerging　research　topics.　The　results　imply　that　China　and　the　United　States　(USA)　are　the　leading　countries　in　terms　of　publication　output.　The　Chinese　Academy　of　Sciences　is　the　most　productive　research　institution,　followed　by　Beijing　Normal　University　and　the　University　of　Sydney.　The　Journal　of　Cleaner　Production,　Ecological　Economics,　and　Energy　Policy　are　the　top　mainstream　journals　in　the　input-output　analysis-related　field.　Based　on　network　analysis,　this　paper　also　discovers　the　hidden　collaboration　patterns　and　interrelations　of　countries,　institutions,　and　authors.　The　bibliographic　coupling　and　keywords　concurrence　networks　are　adopted　to　illustrate　the　input-output　analysis　evolution　over　time,　and　identify　the　current　key　research　hotspots.　The　obtained　results　will　help　scientific　researchers　better　understand　the　research　status　and　frontier　trends　in　this　field,　permit　researchers　to　know　the　current　research　interests　in　the　input-output　analysis　field,　and　provide　useful　information　for　further　investigation　and　publication　strategies.
