Compared　to　the　science-technology　linkages,　the　linkages　among　science,　technology,　and　industry　are　largely　under-studied.　Therefore,　this　paper　proposes　a　main　path　analysis　based　framework　to　discover　the　science-technology-industry　linkages,　in　which　scientific　publications,　patents,　and　products　are　viewed　as　respective　proxies　of　scientific　research,　technological　advance,　and　industrial　development.　To　validate　the　feasibility　and　effectiveness　of　our　framework,　after　the　DrugBank　dataset　in　pharmaceutical　industry　was　downloaded　in　XML　form　on　1　November　2019,　this　dataset　is　further　enriched,　drug　entity　mentions　are　recognized　from　scholarly　articles　and　patents,　and　several　citation　cycles　are　eliminated.　The　scientific　publications　span　from　1871　to　2019,　and　patents　from　1953　to　2019.　There　are　8,421,　5,590,　and　2,136　article,　patent,　and　drug　nodes　and　41,200　citations　in　the　largest　weakly　connected　component　of　the　constructed　heterogeneous　citation　network.　From　empirical　analysis　on　the　largest　weakly　connected　component,　main　conclusions　can　be　drawn　as　follows.　(1)　The　discovered　developmental　trajectories　indeed　encode　the　interactions　among　science,　technology,　and　industry.　Science　and　technology　not　only　interact　with　each　other,　but　also　jointly　promote　the　development　of　the　industry,　and　the　industry,　in　turn,　influences　the　advancement　of　science　and　technology.　(2)　The　developmental　modes　in　the　pharmaceutical　industry　can　be　grouped　into　three　categories:　pushed　by　only　science,　pushed　by　only　technology,　and　pushed　by　science　and　technology　simultaneously.　(3)　The　drugs　bridge　scientific　research　and　technological　advance,　and　thereby　help　enhance　knowledge　exchanges　between　science　and　technology　and　shorten　the　cycle　of　drug　development.　This　study　contributes　to　discovering　the　linkages　among　science,　technology,　and　industry　from　the　perspective　of　mutual　citations　among　scholarly　articles,　patents,　and　products.　However,　a　scientific　verification　of　our　framework　in　other　industries　apart　from　pharmaceutical　industry　still　needs　to　be　further　investigated.
