Along　with　the　development　of　the　externalization　of　R&D,　R&D　activities　are　showing　the　trend　of　their　industrialization.　The　paper　provides　in　the　first　place　the　definition　of　the　R&D　service　industry　with　the　discussion　of　the　differences　between　the　R&D　service　industry　and　its　related　industries,　such　as　the　cultural　industry,　the　creative　industry,　the　information　technology　industry,　the　traditional　service　industry.　Then　it　goes　on　to　analyze　the　causation　of　the　emergence　of　the　R&D　service　industry　with　the　advancement　of　the　structure　of　sub-industries　based　on　those　of　R&D　services　industry.　Finally,　the　paper　estimates　the　general　trend　of　R&D　services　industry　and　argues　the　reasons　why　we　should　develop　the　R&D　service　industry.　(c)　2006　PICMET.
