ICT R&D and Technology Knowledge Flows in Korea

ThisstudymeasuredtheR&DoutcomesofKorea’sfirmsbyanalyzingthechangesandpatternsof technologyknowledgeflowsandtriedtoseewhethertheoutcomesofICTR&Dwerebetterthan thoseofnon-ICTR&D.Usingtheregisteredpatentdatafrom2008and2009,theauthorscomputed thetechnologycycletime(TCT)andvariouscentralityindexeswithsocialnetworkanalysis(SNA), apopularmethodinpatentcitationanalyses(PCA).Inparticular,theauthorsdevelopedatechnology spillovernetworkandindustryabsorptionnetworkfortheSNA.Havingdonetheseanalyses,this studyadditionallyconductedaconfirmatorystatisticaltesttocompareICTR&Dwithnon-ICTR&D intermsoftheirperformances.TheauthorsfoundthatKorea’sICTR&Dhasachievedhigherlevels of technologydevelopment speed, technology spillover and industry absorptionwhencompared tonon-ICTsegments.TheauthorswerealsoabletodeterminewhichparticularICTR&Disinan importantpositionintermsoftechnologyknowledgeflows.
