Snazna konkurencija medu turistickim odredistima potice interes za meduodredisnu suradnju kao alat za razvoj inovativnih zajednickih proizvoda razlicitih odredista. U studiji predstavljenoj u ovome radu istrazeni su motivi, prepreke i ocekivani ishodi meduodredisne suradnje u dvama mediteranskim turistickim odredistima - Opatiji i Portorozu - koja su prepoznata kao medusobno zamjenjiva turisticka odredista. Intervjuirano je dvadeset predstavnika menadzerskog sektora zaposlenih u turistickim organizacijama ili organizacijama povezanima s turizmom u Opatiji i Portorozu, s ciljem ispitivanja njihove percepcije meduodredisne suradnje. Istrazivanje je pokazalo kako je meduodredisna suradnja prepoznata kao vazan alat za povezivanje turistickih proizvoda razvijenih na razini pojedinacnog odredista s ciljem razvoja zajednickih proizvoda razlicitih odredista. Osim toga, istrazivanjem su osvijetljeni motivi za meduodredisnu suradnju na temelju komplementarnosti odredista, prepreke za meduodredisnu suradnju na temelju njihovih slicnosti te razlike i ocekivani ishodi meduodredisne suradnje kojom se povezuju proizvodi koji su razvijeni zasebno, na razini pojedinacnog odredista. Sudionici su izrazili pozitivan stav o inovativnoj turistickoj ponudi i aranzmanima za nova i udaljena trzista s ciljem nadilazenja sezonalnosti i poboljsanja kvalitete proizvoda odredista. Osim toga, rezultati su pokazali kako se meduodredisna suradnja moze uspjesno primijeniti u medusobno zamjenjivim odredistima u kojima postoji slaba unutarodredisna suradnja. U radu se razmatraju i prakticne implikacije rezultata te daljnja istrazivanja. / Intense competition among tourist destinations raises interest in inter-destination collaboration as a tool for developing innovative inter-destination products. The study presented in this paper examined the motives, barriers and expected outcomes of inter-destination collaboration in two Mediterranean tourist destinations Opatija and Portoro that are recognised as good mutual substitutes for tourists. Twenty management-level representatives of tourism or tourism-related organisations in Opatija and Portoro were interviewed to evaluate how they perceived inter-destination collaboration. The study revealed that inter-destination collaboration is recognised as an important tool for bridging the tourism destination products that are designed internally in order to develop inter-destination products. The study also revealed the motives for inter-destination collaboration based on the destinations complementarity, collaboration barriers based on the destinations similarities as well as differences and outcomes that are expected from inter-destination collaboration that bridges the tourism products developed separately in each destination. Participants expressed positive attitudes towards an innovative tourist offer and arrangements for the new and distant markets aiming to overcome the seasonality and upgrade the quality of destination products. Furthermore, the findings indicated that inter-destination collaboration might be successfully employed between destinations with poor intra-destination collaboration that are close substitutes. Practical implications of the results are discussed and further research is considered.
