2.WHATAREINDUSTRIALCLUSTERS?Duringthe1990stheexplosionofspecializedandpopularliteratureonindustrialclustersgavethemanunprecedentedrelevanceacrossarangeofareas,includingbusinessmanagementandeconomic,political,publicandsocialpol-icy.Therewasalsoadegreeofconfusionoverwhatthevariousauthorsmean––anddonotmean––byindustrialclusters.Ourfirstconsid-erationthereforeisterminology.
Itisimportanttopointoutfromtheoutsetthatwearenotconcernedherewiththekindsofeconomicagglomerationsfoundinlargecitiesandurbandevelopmentsofacertainsize.Asvariousauthorshavenoted,largeurbanrealitiesofnecessityandalmostinevitablyprovideopportunitiesforagglomerationsofsortstoemerge,humanfirst,socialandeco-nomicnext(Gordon&McCann,2000).Indeed,itisobvioustothosefamiliarwithlargecitiesandurbanrealitiesthateconomicinteractionswithinthesekindsofagglomerationsaretypi-callygovernedbythelogicoflargenumbersandrandomevents.But,twobasickindsofeconomicbenefitsthatareimportanttoourunderstandingofindustrialclusterscanalsousuallybefoundhere.

Theideaoflocalizedeconomiesofscaleingeographicagglomerationshasalonghistoryineconomics,goingbacktoAdamSmith’searlyobservationsoflaborspecializationandtoMarshall’s(1925)explanationsofwhyfirmscontinuetolocalizeinthesameareas.Marshallhighlightedthreekeyexplanations.First,firmsgetclosetogethergeographicallybecausethisallowsthemtodevelopapoolofspecializedlaborthatishighlyskilledforthespecificneedsofanindustryandrelativelyeasyforthefirmsinneedoftheseskillstoaccess.Second,thesefirmscanprovidenontradedinputspecifictoanindustry,i.e.bylocalizingthemselvesinclosegeographicproximity,thefirmscanexperienceeconomiesofscaleindevelopingandusingcommontechnologiesoraparticularcapitalinfrastructure.Third,firmsthatjointogethergeographicallycangenerateamaximumflowofinformationandideas.Inotherwords,prod-uct,marketandtechnologicalknowledgecanbemoreeasilysharedandmoreeffectivelyturnedintovaluableinnovationsbetweenagentsthatareinclosegeographicproximitythanbetweenagentsthataremoregeographi-callydispersed.

Thereisnothinginherentlyspatialaboutthesocial-networkmodelalthoughithasexplicitspatialapplica-tions.Thisisbecausesocialnetworksareaformofdurablesocialcapital,created(andmaintained)throughacombinationofsocialhistoryandongoingcollectiveaction.
Someauthorsinthesociologicalliterature(Granovetter,1992)havearguedthatindustrialclusterscanbeconsideredasdistinctfrom‘‘socialnetworks.’’Whereastheformerarelargelydominatedbyconstellationsofeco-nomicagentslinkedbycontracts(Pitelis,1993;Williamson,1985),thelatter––theseauthorsargue––aredominatedbyintensiveknowledgeinteractionsbetweenfirmsthatareoftenstrongerthanintra-firminteractions.Althoughtheseviewscanbeseenasasociologicalresponsetoneo-classicaleconomicargumentsinthisarea,conceptualparsimonywouldappeartobedesirableforthepurposesofthepresentstudy.Thus,inthisresearchweprefertoconsidersocialnetworkslargelyasaparti-culartypeofindustrialcluster,inwhichknowledgeintegrationbetweenfirmsaswellasinstitutionalizedtrustandpersonalinteractionsbetweeneconomicagentsareespeciallystrong.Furthermore,differentiatingthequalityandcomplexityofknowledgeinteractionswithinindustrialclustersaccordingtothetypeofindustry––i.e.‘‘high-tech’’vs.‘‘basic’’or‘‘mature’’––seemstobebasedonratherfeebleargumentsandlittleempiricalevidence.Indeed,anumberofauthorssuggestthatindustrialclustersincentralItalyformedaroundseem-inglybasictechnologiessuchastilemanufac-turingdemonstrateknowledgeinteractionsthatareassociallycomplex,pervasiveandinnova-tiveasanyfoundinthebiotechnology,tele-communicationsorcomputersoftwareclusters(Gordon&McCann,2000).Thecrucialdiffer-enceinthiscontextseemstostemfromthedegreetowhichtheeconomicagentsinanindustrialclusterdecidetoengageinpurposefulcollaborationandcontinuouscooperationacrosscriticalactivitiesthatareofcommoninteresttoall––whilekeepingthecompetitivemarketdynamicsintact.Simultaneouscooper-ationandcompetitioninaclearlydefinedgeographicareainturnrequiresahighlydevelopedsocialfabricthatengagesandfacil-itatestheintegrationofknowledgeandcom-municationexchangesaswellasthefosteringofacommonsenseofidentityamongecono-micagents.Asaresult––almostirrespectiveofthetechnologicalcharacteristicsofanygivenindustry––thedegreeofknowledgeintegration

Therearecertaincostsassociatedwithindustrialclustersthatsometimesserveasobstaclestogrowth.Althoughthereiscertainlyadegreeofincreasedcompetitionandconges-tiononboththedemandandsupplysides,industrialclusterscanalsoexperiencehighratesofemployeeturnoverandnoncooperationbetweenfirms,whichcanjeopardizetheentirecluster.Asmentioned,thewayinwhichanindustrialcluster’sagentsmanagetoorches-tratemutualcooperationwhileatthesametimefosteringgreatercompetitionmightbecomecrucialtothecluster’slong-termeconomicsurvival(Swann&Prevezer,1996).
4.WHOBELONGSTOINDUSTRIAL
CLUSTERS?Ourdefinitionofindustrialclustersincludesaclose-knitsocialcommunityofpeopleandabroadsetofeconomicagents,notjustfirms.StudiesthatlookatEmiliaRomagna’sindus-trialdistrictsinItalyoffersomeofthemoststrikingcharacterizationsofcohesivesocialcommunitiesactivelyunderpinningtheeco-nomicstrengthofclusters(Becattini,1990,p.39):

Industrialclustersalsoincludeapopulationofeconomicagents––firmsaswellasindividu-als––withspecializedskillsorknowledgerele-vanttothelinkedeconomicactivitiesthatarecarriedout.Inaddition,theseeconomicagentscompriseinstitutionssuchasuniversities,researchcenters,industryassociationsandtechnologicalinstitutes,whichfostermutualeconomiccooperationandthesharingoftechnologicalknowledgeamongthemembersofanindustrialcluster.Thesekindsofinstitu-tionshavebeenreferredtoascomprisingan‘‘associationaleconomy’’(Schmitz,2000)orconstitutinga‘‘meso-level’’(Meyer-Stamer,1999)betweenthemacro-levelofeconomicpolicy2andthemicro-levelofafirm’scompeti-tion.Theavailableempiricalevidencesuggeststhatclose-knitsocialcommunitiesareasigni-ficantfactorbehindtheeconomicstrengthandsustainabilityofindustrialclusters(Pyke,Becattini,&Sengenberger,1990).Inaddition,associationalormeso-levelagentshavebeenfoundtobeeffectiveinpromotingcooperationfor‘‘goodpurposes’’whichisconsideredtohaveasignificantperformance-enhancingeffectforfirmslocatedinadvancedcountryregions.Thisisparticularlythecaseforfirmsseekingtocompetesuccessfullyininternationalandglobalmarkets(Hudson,1998).
5.WHYISGEOGRAPHICCLOSENESSSO
IMPORTANT?Furthermore,ourdefinitionofindustrialclustersstressesthenotionthatthemembersofsuchaclusterarelocalizedincloseproximitywithinaparticulargeographicregion.Wearethereforeconcernedherewiththetypesofeconomicadvantagesstrictlystemmingfromahighdegreeofgeographicconcentrationamongfirms.Thesetypesofeconomicadvantageshavebeenwelldescribedintheclassicalandneo-classicaleconomictraditionexaminingindus-trialcomplexes(Czamanski&Ablas,1979;Feser&Bergman,2000).Asinthecaseofindustrialclusters,industrialcomplexescandevelopinternaleconomiesofscaleintermsofspecifictradinglinksandcustomer–supplierrelationships.Conversely,innovativefirmscanbeheavilydependentonlocalnetworkingor
linkagestosupporttheirnovelproductsandservices.Notethatbothoftheseadvantagesarestrictlydependentupontheclosegeographicproximityofthefirmslocalizedwithinanindustrialcluster.Thisisdifferentfromthetypicalglobalizationeconomies,whichreducetheimportanceoftraditionallocalizedfactorsofproduction,orfromthetypesofinnovationsrelyingoninputsthatareunlikelytobelocallyconfined(Simmie&Sennett,1999).
Itmustbenoted,however,thatgeographicproximitycouldbringasmanydisadvantagestothemembersofindustrialclustersasitpro-videsadvantages.Disadvantagesincludethepoachingofspecializedlaborbetweenfirms,greatercompetition(whichcanalso,however,beanadvantage),fasterimitationofbothtechnologyandproductinnovationsbycom-petitors,andsharedmarketintelligenceamongfirms.GordonandMcCann’s(2000)studyoftheeffectsofgeographicproximityonrelatedactivitiesbyindustrialsectorinLondoncon-cludesthat––outof17sectorsexamined––onlyprintingandpublishingandfinancialservicesshowclearnetadvantagesofproximity.Thistypeofempiricalevidenceraisesafundamentalissue:howdomembersofindustrialclustersworktogethertobalancethedisadvantagesandadvantagesofgeographicproximity?
6.HOWDOMEMBERSOFINDUSTRIAL
CLUSTERSCOMBINE?Ourdefinitionofindustrialclustershigh-lightsthatitsmembersworktogetherinrelatedorlinkedbusinessactivities.Indeed,thescale-andknowledge-basedadvantagesgeneratedwithinanindustrialclusterstemfromboththenumberandthenatureoftheparticularlink-agesbetweenitsmembers.Inawell-developedindustrialcluster,theselinkagescanbenumer-ous,uniqueandspecializedtotheindustrialcluster,including:

Ithasbeenshownthatthenumberandeconomicvalueofthesekindsoflinkscanprovideanadequateindicationofanindus-trialcluster’sstrength(Feser&Bergman,2000).Forexample,empiricalresearchbySwannandPrevezer(1996)suggeststhatclustersinindustrieswheremultiplelinkagescanbecreatedamongthememberfirms(suchasthecomputerindustry)presentsignificantlystrongergrowthpatternsthanclustersinindustrieswithmuchlowerlinkagesbetweenmemberfirms(suchasthebiotechnologyindustry).
7.WHATBINDSINDUSTRIALCLUSTERSTOGETHER?Next,ourdefinitionstressesthatmembersofanindustrialclustermustshareandnurtureacommonstockofproduct,technologyandorganizationalknowledge.Indeed,someauthorshavedescribedthiscriticalcharacter-isticofindustrialclustersasconstitutinga‘‘socialglue’’(Porter,1998)thatbindstheclustertogether.Othershavereferredtoa‘‘commonglue’’oran‘‘organizationalglue’’thatsociallyamalgamatesdiversestructuralagentsandintegrateskeyknowledgeacrosscultural,organizationalandfunctionalbound-aries(Evans,1993;Morosini,2002).
Ontheonehand,Porter(1998,p.88)high-lightsthat:
Thesocialgluethatbindsclusterstogetheralsofacilitatesaccesstoimportantresourcesandinfor-mation.Tappingintothecompetitivelyvaluableassetswithinaclusterrequirespersonalrelation-ships,face-to-facecontact,asenseofcommoninter-est,and‘‘insider’’status.Themerecollocationofcompanies,suppliers,andinstitutionscreatesthepotentialforeconomicvalue;itdoesnotnecessarilyensureitsrealization.
Ontheotherhand,Morosini(2002)identifiesfivekeycapabilitiesthatneedtobeinplacetobuildthis‘‘commonglue’’thatrealizeseco-nomicvaluewithin––andacross––economicorganizations.Whenappliedtoindustrialclusters,thesekeycapabilitiescanbecharac-terizedasfollows:
(a)Leadership––Well-functioningindustrialclustersaredeliberatelyamalgamatedbygroupsofkeyindividualswithexplicitrolesfosteringmutualcooperation,knowledgesharing,leadershipcoachingandarbitration
ofdisputesthatareseenasbenefitingthecommoninterestsofthemembersofthecluster.Theseindividualsareidentifiedandtheirrolesareexplicitlyacceptedbyalltheagentsthatbelongtothecluster.Manyauthorshavedocumentedtheseleadershiprolesinthecontextofdifferentindustrialclusters.Forexample,inhisroleasindustryassociationrepresentativeduringthe1990s,thepresidentofalargetextilemanufacturingcompanyinsouthernBrazil’sSantaCata-rinaregionledafive-yearradicaltransfor-mationthatturnedtheareafromafiercelycompetitivetoacloselycollaborativeindus-trialclusterinthissector(Meyer-Stamer,1999).OtherauthorshaveobservedthatCEOsandseniorexecutivesofestablishedtechnologyfirmsinSiliconValleycontinu-ouslyidentifypromisingyoungentrepre-neursandspendtimecoachingandgrowingtheirleadershiptalents––oftenhelp-ingtoappointthemtoseniorpositionsincompetingfirms(Leonard&Swap,2000).Moreover,leadersoflargeandsmallfirmsinMexico’sGuadalajarafootwearclusterwereseentohaveworkedcloselytogetherinthe1980sand1990stodesignandimple-mentacomprehensivejointefforttoover-comethedramaticeffectsofaseriesofmacro-economicshockssuchaslargecur-rencydevaluations(Rabellotti,1999).
(b)Buildingblocks––Well-functioningin-dustrialclustershavetypicallydevelopedaclear,commonstockoforganizationalknowledgethatissharedbyallmembers,acrossfunctional,culturalandfirm-specificboundaries.Thesebuildingblockstypicallyincludestrongsocioculturaltiesamongthelocaleconomicagents,creatingacommoncodeofbehaviorthatfacilitatestrustandac-tivecollaboration;acommonlanguage,notjustintheliteralsensebutalsoencompass-ingcommontechnological,businessandorganizationalterminology;acommonindus-trialcultureandatmosphere;acommonphi-losophyandapproachtodevelopinghumantalentandspecializedlabor;acommonbusi-nessunderstandingofthebasiccompetitivedynamicsoftheirindustry;andcommonap-proachestocompetitiveperformancemea-surement(Meyer-Stamer,1998;Rabellotti,1995;Simmie&Sennett,1999).Empiricalevidencesuggeststhatacommonsystemofsocioculturalandeconomicvalues,alongwithawell-definedsystemofinstitutionsthatsupportsandspreadsthosevalues,is

(c)Communicationrituals––Withinwell-developedindustrialclusters,thereareregu-larcommunicationevents,interactionsandapproachesthatcontinuouslyfosteracom-monsenseofidentityamongallmembersofthecluster.Meyer-Stamer(1999)de-scribessomeofthesecommunicationeventsinthecontextofBrazil’sSantaCatarinatex-tilemanufacturingindustrialcluster,whicharefairlytypicalofsucheventsinsimilarclusterselsewhere(Porter,1998;Schmitz&Nadvi,1994).In1996,forexample,thepres-identofoneofthelargesttextilemanufac-turingfirmsinthearea(mentionedearlier)organizedkeyeventssuchasvisitsforlocalownersandmanagersoftextilefirmstoItaly’stextileclustersinordertolearnbestpracticesininterfirmrelationsandseeworld-classexamplesofsupportivemeso-levelinstitutions.Communicationinteractionsthatsupportthedevelopmentofacommonsenseofidentityinindustrialclustersincludeproactiveindustryassociations,commoninterestgroupstolobbylocalornationalgovernmentsandbuildingacommonimagethroughpublicrelationsinitiativesandthelike.Finally,typicalcommunicationap-proachesthatfosteracommonsenseofiden-tityamongthemembersofanindustrialclustervis-a-vistheoutsideworldincludedevelopingacommonproduct-orquality-brand,aswellascommonandexplicitqual-itystandards.Empiricalstudieshavefoundthatindustrialclusterswithwell-developedcommunicationevents,interactionsandap-proacheshavehigherlevelsofinterfirmcooperationandaremoreadaptabletoabruptchangesinthemacro-economicandcompetitiveenvironment(Pykeetal.,1990).(d)Knowledgeinteractions––Well-function-ingindustrialclustersmusteraseriesofregular,explicitandhighlydevelopedmech-anismsforsharingkeytechnologicalandbusinessknowledgeamongallmembers.Typicalexamplesincludecontinuousbench-markingtaskforces(bothwithintheclusterandacrossclusters);researchcenters,tech-nologicalinstitutes,universities,think-tanks,executiveeducationandworkertrainingschoolsthatactivelypromotemutualcoop-erationandtechnologytransferswithintheindustrialclusterandbetweenfirms;jointR&D,productdesign,manufacturingorco-marketingeffortsbetweenfirms;andex-portandtradingorganizationsbothlocallyandabroad.Inwell-developedindustrialclusters,meso-levelinstitutionssuchasindustryassociationsusuallyplayakeyroleasbothinitiatorsandmanagersofthesecoordinationmechanisms.Itisimportanttonote,however,thatthisroleissubstan-tiallydifferentfromtheconventionalcollec-tivebargaining,politicallobbyistorcontactandnetworkingrolesthatthesekindsofassociationstypicallyplaywithinindustriesorinsidelessdevelopedindustrialclusters(Swann&Prevezer,1996).Theavailableempiricalevidencesuggeststhatindustrialclusterswithwell-developedcoordinationmechanismsshowasignificantlyhigherlevelofcooperationbetweenfirms.Inturn,co-operatingfirmswithintheclustertendtoperformbetterthannoncooperatingones(Schmitz,2000).Cooperationbetweenfirmscanoftenbefacilitatedbytheeconomiccomplementaritybetweenacluster’sagents,whichcanextendupstreamtosuppliers,downstreamtocustomersorlaterallytomanufacturers(Porter,1998).Thisallowsforincreasedefficiencies(e.g.technologies,marketingchannels),aswellasadditionalbenefits(e.g.,thereputationofcertainre-gionsforindustryexcellencebenefitsallofitsmembers)andsynergies(e.g.,consumersofhotelserviceswillvaluetheentireexperi-enceaccordingtothequalityofeachcompo-nent).3(e)Professionalrotations––Withinhighlycompetitiveindustrialclusters,thereistypi-callyasignificantpoolofhumantalentspe-cializedaroundbusinessandtechnologicalknowledgethatisspecifictothecluster’smaineconomicactivities.Thedegreeofcrossfirmmobilityoftheseprofessionalslar-gelytakesplacewithinthegeographicboundariesoftheindustrialcluster.Perhapsthemostconspicuousexampleofthisphe-nomenonisinSiliconValley,wherethetal-entedandentrepreneurialindividualsthatseemtoaboundinthisclustertendtobeex-tremelymobile,eitheracrossfirms(afterrel-ativelyshortworkexperience,onaverage,inanygivenorganization)orinordertostartuptheirownenterprises.But,thesemovesusuallytakeplacewithinthegeographicboundariesoftheValley(Leonard&Swap,2000).ThesecharacteristicshavecertainlyhelpedgiveSiliconValleysomeofitslegend-arycloutandreputationinmostpeople’s

INDUSTRIALCLUSTERSFinally,ourdefinitionstressesthattheulti-mategoalofindustrialclustersistogeneratesuperiorproductsandservicesthatarevaluabletocustomersinthemarketplace.Thereareatleasttwocrucialpointstobemadeaboutthisnotion.First,althoughanindustrialclustermightbenefitfromsomeprotectivemeasuresattheoutset,inthelong-term,selectionmecha-nismsthatreflectthedynamicsofbusinesscompetitionmustbeinplace(Porter,1998).Otherwise,anindustrialclusterwillsimplynotsurvive,oritwilldosoasaresultofeconomictransfersthatarenotnecessarilymarketrela-ted,e.g.,intheformofstatesubsidiesorfiscalincentives.
Second,industrialclustershavenotonlyprovedextremelysuccessfulatcreatingrealeconomicvaluenearlyeverywherebuthavealso––duringthesecondhalfofthe20thcen-tury––emergedasformidableglobalplayersintheirownrightacrossanastonishingvarietyofindustries.Therefore,althoughtheseindustrialclustersaretightlyconfinedgeographically,theirscopeofcompetitionisincreasinglyglobal,notlocal.Whereasthemarketfocusofsomeoftheseindustrialclustersmightremainlocal,globalcompetitioncanneverthelesstakeplaceintheformofnewentrants––whichoftenincludeindustrialclustersaswell.Rabellotti(1999)describesthecaseofaMexicanshoe-makingclusterwhichduringthe1990swaspartlydisplacedinitsmain(local)marketbycheapcompetingproductsfromChineseshoe-makingclusters.
