Compared　to　the　linkages　between　science　and　technology,　the　linkages　among　science,　technology,　and　industry　are　largely　under-studied.　Therefore,　this　paper　proposes　a　main　path　analysis　based　framework　to　discover　the　linkages　among　science,　technology,　and　industry,　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,　the　DrugBank　database　in　pharmaceutical　industry　is　taken　as　our　dataset.　From　empirical　analysis　on　this　dataset,　the　following　conclusions　can　be　drawn:　(1)　The　discovered　developmental　trajectories　indeed　encode　the　interactions　among　science,　technology,　and　industry;　(2)　The　developments　in　pharmaceutical　industry　are　mainly　pushed　by　only　science,　only　technology,　and　science　and　technology　simultaneously;　(3)　The　drugs　can　help　enhance　knowledge　exchanges　between　science　and　technology.　©　Copyright　2023　for　this　paper　by　its　authors.　Use　permitted　under　Creativ　Commons　License　Attribution　4.0　International　(CC　BY　4.0).　CEUR　Workshop　Proceedings　(CEUR-WS.org)
