The concep was ho oughly in oduced in o he li e a u e by Male ba (2002, 2004). In con as o i s closely ela ed geog aphically delinea ed coun e pa s, ha is, na ional sys ems o inno a ion (NSIs) and egional sys ems o inno a ion (RSIs) (Lund all, 1992; Cooke, 1992), in his app oach sec o s a e u ilized as uni s o analysis. SSIs ha e been de ined as “a se o new and es ablished p oduc s o speci ic uses and he se o agen s ca ying ou ma ke and non-ma ke in e ac ions o he c ea ion, p oduc ion and sale o hose p oduc s” (Male ba, 2002: p.250). He e, ollowing Ol a and Sain Jean (2009) and Fabe and Hoppe (2013), SSIs a e discussed h ough he ollowing in e linked hemes: agen s, in e ac ions, and ne wo ks; echnological egimes; ma ke demand; and policy condi ions. 4 ACCEPTED MANUSCRIPT Agen s, in e ac ions, and ne wo ks: As s a ed by Fabe and Hoppe (2013: p.631), “any sec o al sys em analysis in ol es an o e iew o he main agen s in he sec o , including hei in e ac ions and o mal as well as in o mal ne wo ks.” The basic cha ac e is ics o an SSI can hus be desc ibed h ough he agen s ( i ms, uni e si ies, inancial ins i u ions, go e nmen , local au ho i ies, indi iduals, e c.) in ol ed, hei in e ac ions, and he ne wo ks ha ha e been o med due o hese in e ac ions (Male ba, 2002). The agen s can be u he di ided in o p ima y and seconda y agen s. P ima y agen s a e he key playe s o inno a ion wi hin he sec o , ha is, (commonly) inno a i e i ms. Seconda y agen s a e suppo ing o ganiza ions such as he go e nmen , banks, esea ch ins i u es, consul ancies, and in e media ies (Fabe and Hoppe, 2013). Technological egimes: Fi ms ope a e wi hin sec o s cha ac e ized by dis inc echnological en i onmen s, ha is, echnological egimes, which play a key ole in de e mining hei pa e ns o inno a i e ac i i ies. The e a e wo ypes o echnological egimes: 1) an en ep eneu ial egime (cha ac e ized by a con inuous enla gemen o he inno a ion base h ough he en y o new inno a o s) and 2) a ou inized egime (cha ac e ized by he dominance o a ew es ablished con inuously inno a ing i ms) (Male ba and O senigo, 1997; Ol a and Sain Jean, 2009). Since new echnologies can open up oppo uni ies o i ms o ake ad an age o , he discussion ela ed o he ole o echnological ba ie s o en y has led Ma sili (2002) o he a gumen ha he complexi y o he echnology ( he knowledge base upon which i is based) in ol ed wi hin a sec o de e mines o a la ge ex en he likelihood o he eme gence o new ac o s en e ing in o he sec o ( he highe he complexi y, he highe he en y ba ie s). The anspo a ion sec o , also discussed in his pape , is cha ac e ized by high complexi y, which hus se s en y-ba ie s o new i m (cen e ed on eco- inno a ion) o ma ion. Ma ke demand: T adi ionally, inno a ion s udies ha e concen a ed on supply side dynamics, whe eas he demand side o inno a ion a ac ed li le schola ly a en ion (Ol a and Sain Jean, 2009). Two no ions challenged his passi e oice gi en o ma ke demand: 1) he no ion o he eme gence o dominan design (Abe na hy and U e back, 1978) and 2) he no ion o inc easing e u ns on inno a ion adop ion ela ed o, o example, scale economies in p oduc ion and echnological in e ela edness (A hu , 1988). I was ealized ha ma ke demand condi ions can po en ially lead o a echnological monopoly and an e a o inc emen al imp o emen s (Ol a and Sain Jean, 2009). Howe e , new dis up i e inno a ion can displace a dominan echnology i he e is a willing g oup o niche consume s adop ing and expe imen ing wi h new echnologies (Male ba e al., 2007). The incen i e o i ms o de elop en i onmen al inno a ion can hus come om he ma ke h ough he non- egula o y p essu e o “g een consume s” (Fos e and G een, 2002; Ol a and Sain Jean, 2009). Fi ms should also conside he ma ke as a po en ial coope a ion pa ne by in eg a ing use s in o he de elopmen p ocesses o en i onmen al inno a ion (Wagne , 2009; Ca illo-He mosilla e al., 2010). Policy condi ions: Since echnology-push wi hin a sec o and ma ke -pull alone do no seem o be s ong enough incen i es o en i onmen al inno a ion, public policies aimed a acili a ing sus ainabili y ( egula o y push/pull e ec s) a e commonly needed (Rennings, 2000). Policies can be aimed a acili a ing demand-pull o echnology-push condi ions o en i onmen al inno a ion depending on how hey a e designed (Ol a and Sain Jean, 2009). Demand-pull policy ins umen s a e measu es aimed a aising he payo o success ul inno a ions h ough ac i i ies such as 5 ACCEPTED MANUSCRIPT en i onmen al egula ions, s anda ds, and axes on compe ing echnologies. Technology-push policy ins umen s a e measu es a ge ed a incen i izing inno a i e ac i i ies by educing he cos s o de eloping en i onmen ally iendly p oduc s, se ices, and p ocesses h ough, o example, ax c edi s and di ec unding o esea ch and de elopmen (R&D) (Neme , 2009; Makkonen and Repka, 2016). The combina ions o hese policy ins umen s de ine he en i onmen al inno a ion policy mix ha is u ilized o p omo ing sus ainable sec o al sys ems o p oduc ion and consump ion (Ol a and Sain Jean, 2009). This policy mix is in luenced by a ying geog aphical scales, since he policies can be designed a local, na ional, o in e na ional le els. I is a he unsu p ising ha he exac policy mix o indi idual measu es ha would be he mos e ec i e a p oducing he bes esul s emain elusi e (Cos an ini e al., 2017). Despi e his unce ain y, i is commonly ag eed ha egula ions (and o he policy ins umen s) play an impo an ole in shaping he unc ioning o SSIs in connec ion o en i onmen al inno a ion (Ol a and Sain Jean, 2009; Fabe and Hoppe, 2013). 2.2 Technological sys ems o inno a ion Dis inc om i s geog aphical (RSIs and NSIs) and sec o al (SSIs) coun e pa s, in TSIs he uni o analysis is a speci ic echnology o p oduc . The concep was coined by Ca lsson and S ankiewicz (1991: p.111) and was de ined as “a ne wo k o agen s in e ac ing in a speci ic economic/indus ial a ea unde a pa icula ins i u ional in as uc u e o se o in as uc u es and in ol ed in he gene a ion, di usion, and u iliza ion o echnology.” A TSI does no necessa ily exis in e e y a bi a ily chosen ield, a he a TSI needs o mee a ce ain se o condi ions. The e should be 1) a a ie y o di e en ac o s pu suing di e en inno a ion s a egies, 2) a ce ain di ision o labo be ween hese ac o s, 3) a a ie y o (lobbying and classi ica ion) ins i u ions, and 4) a leas some ma ke ansac ions (Ma ka d and T u e , 2008). Hekke e al. (2007) and Be gek e al. (2008) ha e in oduced p ac ical schemes o e alua ing he o e all unc ioning o a TSI, which is impac ed by key p ocesses ( e med unc ions) ha can be po en ially in luenced by policy-make s. This “ unc ions app oach” has been ex ensi ely applied in a wide ange o s udies o en i onmen al inno a ion, sus ainabili y, and echnological change (e.g. Neg o e al., 2008; Suu s and Hekke , 2009; Foxon e al., 2010; Suu s e al., 2010; Tigabu e al., 2015; Reicha d e al., 2016). The unc ions app oach is employed he e as an analy ical amewo k o desc ibing he TSI o MSSs by acing he ollowing s eps: s uc u al componen s; unc ional pa e ns; and policy issues. S uc u al componen s: The ocus o esea ch on TSIs can be placed on a dis inc knowledge ield o p oduc (he e he emphasis is placed on a p oduc , namely MSSs). Thus, he analysis s a s wi h iden i ying he ac o s in ol ed as well as he ne wo ks ha exis be ween hem. The ac o s commonly include i ms, uni e si ies, esea ch ins i u es, public bodies, e c. Mo eo e , ins i u ions ( h ough laws and egula ions) in luence he TSI in ques ion (Jacobsson and Be gek, 2004; Be gek e al., 2008). Func ional pa e ns: Fo any analysis o go beyond he me e desc ip ion o he s uc u e o a TSI i is necessa y o mo e on o analyzing i s unc ions (o key p ocesses). These unc ions include he ollowing (Hekke e al., 2007; Be gek e al., 2008): 1) knowledge de elopmen and di usion, 2) in luence on he di ec ion o sea ch, 3) en ep eneu ial ac i i ies/expe imen a ion, 4) ma ke o ma ion, 5) legi ima ion, 6) esou ce mobiliza ion, and 7) de elopmen o posi i e ex e nali ies. 6 ACCEPTED MANUSCRIPT The i s unc ion na u ally e e s o he knowledge base o he TSI ( ypes and sou ces o knowledge).

Finally, he de elopmen o posi i e ex e nali ies om new i ms en e ing he TSI conce ns he eme gence o pooled labo ma ke s, eme gence o specialized goods and se ice p o ide s as well as knowledge spillo e s. Some au ho s (e.g. And easen and So acool, 2015) include bene i s ha occu o he socie y as a whole, such as educed emissions, o his lis . These unc ions a e no comple ely independen om each o he , a he hey o m a sequence o p ocesses whe e he indi idual unc ions coe ol e (Hekke e al., 2007; Be gek e al., 2008). Policy issues: The in e nal dynamics o a TSI alone a e only a pa ial explana ion o i s success: inducemen and blocking mechanisms in luence he unc ioning o a TSI. Fo example, a s ong belie in he g ow h po en ial o a speci ic echnology o a new go e nmen policy (such as ax c edi s o cheap loans) on conduc ing R&D can ac as an incen i e ha p omo es he de elopmen o a TSI. In con as , blocking mechanisms, such as a poo ly de eloped ma ke o a p oduc , can ha e s ong nega i e impac s (Jacobsson and Be gek, 2004; Neg o e al., 2012). Policies should a ge TSIs by measu es ha s eng hen inducemen mechanisms and emo e blocking mechanisms (Be gek e al., 2008). 2.3 Concep ual amewo k: Bounda ies o sec o al and echnological sys ems o inno a ion As discussed by Male ba (2002) and Ol a and Sain Jean (2009) he li e a u e on SSIs should pay close a en ion o he e olu ion o ans o ma ion o bounda ies be ween sec o s. This is pa icula ly ele an o en i onmen al inno a ion, which can o en be a p oduc o combining di e en echnologies p esen in a ious dis inc sec o s (Cooke, 2008). The e o e, when discussing en i onmen al inno a ion, one commonly s udies a ield ha has combined exis ing echnology om a ious sec o s in an in eg a i e manne . Simila ly, TSIs commonly c oss sec o al and geog aphic bounda ies (Figu e 1) (Ma ka d and T u e , 2008; S ephan e al., 2017). The e o e, cau ion is equi ed when se ing (de ini e) sec o al and/o e i o ial bounda ies o TSIs (Be gek e al., 2015). A TSI can be a subsys em o a SSI (a knowledge base which is exclusi e o an indi idual sec o ) o an amalgama ion o se e al ela ed sec o s (a mo e gene ic knowledge ield in ol ing many sec o s) (Be gek e al., 2008; Ma ka d and T u e , 2008). TSIs can be geog aphically bounded in a egion (RSI) o a na ion (NSI) bu a e mo e commonly in e na ional, o e en global, in na u e (Binz e al., 2014; Binz and Tu e , 2017). In ac , Be gek e al.
