In　this　paper,　we　seek　to　explore　the　agglomeration　externalities　of　creative　industries　impacting　on　industrial　efficiency,　both　at　the　regional　level　and　at　the　sector　level.　Firstly,　we　apply　a　data　envelopment　analysis　model　to　compute　the　efficiency　scores　of　creative　industries　in　China.　The　result　shows　that　China＇s　industrial　efficiency　whether　in　different　provinces　or　different　creative　sectors　is　characterized　by　huge　disparities.　Secondly,　using　the　data　from　China＇s　31　provinces　and　50　creative　sectors　during　the　period　of　2004-2014,　we　empirically　explore　whether　and　how　the　development　of　creative　industries　agglomeration　impact　on　industrial　efficiency,　where　the　agglomeration　is　distinguished　between　regional　specialization,　geographical　concentration,　and　industrial　concentration.　We　find　that　the　three　types　of　agglomeration　externalities　all　play　important　roles　in　increasing　productive　efficiency　in　creative　industries.　The　study　also　confirms　that　industrial　efficiency　is　more　likely　to　be　increased　by　attracting　much　smaller　firms　concentrating　in　a　given　area,　while　this　effect　is　mixed　in　a　given　creative　sector.
