This　paper　presents　an　empirical　study　on　the　technology　opportunities　potential　analysis　with　a　case　example　of　LED　by　combining　bibliometrics　analysis,　morphology　analysis　and　conjoint　analysis　methods.　At　first,　bibliometrics　analysis　and　technology　morphology　matrix　are　used　to　establish　all　kind　of　technology　configurations　in　possibility;　then,　the　technology　unoccupied　configurations　are　identified　by　the　documents　keywords　vectors;　at　last　the　priority　of　each　technology　configuration　can　be　calculated　by　the　conjoint　analysis　based　on　the　citation　of　technology　documents.　The　results　reveal　that　this　proposed　method　not　only　can　solve　the　limitations　of　using　single　method,　but　also　can　prioritize　the　unoccupied　territory　of　technology　configurations,　in　order　to　identify　and　evaluate　the　technology　opportunities　more　scientifically.　©　2008　PICMET.
