目前台灣地方政府間的合作非常有限，多停留在共同宣言和研討會的層次，並侷限於交通、垃圾處理等議題。相反的，德國具有地方合作的傳統以及各類型的合作模式，因此，德國經驗對於一直缺少合作經驗的台灣而言，當具有高度的參考價值。經過對台灣和德國跨域合作做比較分析之後，本研究認為，台灣的跨域合作應有根本性的改變，也就是不只要有非正式組織，更要從非正式組織進入正式合作的階段，具體的建議包括：以積極取代消極合作、立法地方合作法和修訂財劃法、成立直轄市論壇、都會區公司、縣市聯合協會、建立網絡式上下整合的合作平台、建立災害防救的負責伙伴關係等。

Currently there is yet little cooperation between local governments inTaiwan. Among the few cooperative efforts, most stay in the level of commonmanifest or symposiums with agendas limited to such as traffic and garbagedisposal. In contrast, Germany is noted for its tradition in the cooperationamong local governments in various ways. In this regard, Taiwan may learnand benefit a great deal from Germany. The current study conductedcomparative analysis between Taiwan and Germany and proposed that afundamental change is needed in terms of collaboration among localgovernments, which suggests escalating the current informal mode ofcooperation to a formal level. The study also offered concrete recommendationswhich include: (1) encourage proactive cooperation, (2) draw up thecollaboration of local governments Act and revise the allocation of fiscalrevenue and expenditure Act, and (3) found Direct-controlled municipalityforums, Limited liability companies from public and private sectors, national associations of cities and municipalities, and platforms to facilitate both verticaland horizontal cooperation among governments.
