Die Wertschöpfungskette für frisches Obst und Gemüse in Deutschland hat sich in den letzten Jahrzehnten stark gewandelt. Die Konzentration im Einzelhandel, andere Konsumgewohnheiten und verbesserte Logistik haben Beschaffung und Angebot stark verändert. Daneben sind neue Stakeholder aufgetreten, die erfolgreich die Umsetzung ihrer Anliegen einforderten, was zu höheren Anforderungen an Produktsicherheit und Qualität führte. In der Wissenschaft beschäftigte man sich bislang nur wenig mit der Wertschöpfungskette für frisches Obst und Gemüse in Deutschland. Einige Autoren erforschten die Mechanismen, wie britische Supermärkte Gemüse aus Ostafrika importierten. Das Modell der Value Chain Analysis und die Transaktionskostentheorie bilden den theoretischen Rahmen der vorliegenden Arbeit. Erster Schritt war die Identifizierung der relevanten Akteure und ihrer Position in der Kette. Es zeigte sich, daß es keine einheitliche Value Chain gibt, sondern daß die Beschaffung der einzelnen Produkte unter-schiedlich organisiert ist, sowohl von Unternehmen zu Unternehmen, aber auch innerhalb einer Firma für unterschiedliche Produkte. In einem zweiten Schritt wurden sorgfältig ausgewählte Experten aus Produktion, Zwischen- und Einzelhandel zu den Veränderungen in der Value Chain und deren aktueller Ausgestaltung interviewt. Besonderer Wert wurde dabei auf die Ver-träge und Beziehungen zwischen den einzelnen Handelspartnern gelegt, d.h. wie diese zustande kommen, wie sie aufgebaut sind und wie die Kontrolle der Vereinbarungen funktioniert. In einem letzten Schritt wurden die Faktoren herausgearbeitet, die für das aktuelle Aussehen der Value Chain entscheidend sind. Weitere Ergebnisse waren, wie das Governance-System in der Realität funktioniert, wie konsequent Vorgaben und Standards umgesetzt werden und wie die Verbindungen zwischen den einzelnen Partnern gestaltet sind. Dabei kristallisierten sich drei unterschiedliche Einkaufstypen im LEH heraus. / The value chain for fresh fruit and vegetables in Germany has changed considerably through-out the last decades. The convergence in retail, transformed consumer habits and improved logistics have had great impact on procurement and supply. In addition, new stakeholders have emerged, who successfully demand the implementation of their requirements, resulting in a higher demand for product safety and product quality. So far, science has addressed the value chain model on fresh fruit and vegetables in Germany only briefly. In fact, there are only few studies available on the mechanisms of UK supermar-ket imports of vegetables from East Africa. The model of the Value Chain Analysis and the transaction cost theory should hence form the theoretical framework of this study. The first step was the identification of relevant players and their position within the chain. It was found that there is no single value chain present, but that the procurement of the individ-ual products is organized, changing, both from company to company, but also within a com-pany for different products. In a second step, a group of carefully selected experts from production, intermediary trade and retail were asked to comment on the changes and the current structure of the value chain. Special emphasis was placed on the contracts and relationships between the individual trading partners, i.e. how these agreements are made, what do they include and how their compliance is guaranteed. In a last step, the crucial factors were identified that are critical for the current appearance of the Value Chain. Other results included the determination of the true governance system, findings about how consistent the guidelines and standards are implemented and how the connections between the individual partners are designed. As a result, three different procurement types can be de-termined in food retailing.

This thesis explores the opportunities, challenges, and initiatives for coffee tourism in the context of Ethiopia. My research addresses five themes to achieve its research aims, which are as follows: arriving at prospective coffee tourism frameworks; addressing the reasons behind the underdevelopment of coffee tourism in Ethiopia; highlighting coffee tourism’s opportunities and challenges in Ethiopia; identifying potential coffee tourists, and; initiating coffee tourism through local collaborations. The core research methodologies are: fieldwork in Ethiopia involving a series of interviews with key stakeholders and a detailed case study of one potential coffee tourism region; digital ethnography, and; knowledge transfer activities enabled by several conceptual approaches such as development in Africa, power relations, reformed orientalism, situated knowledge, self-other, emotional geographies, and participatory geographies. Through this research, I found that coffee tourism cannot simply be a combination of coffee and tourism; coffee tourism needs to be understood through various contexts in addition to that of tourism; coffee tourism can be a more practical tourism form and a new coffee marketing vehicle in Ethiopia, and; coffee tourism potentially brings more advantages to the coffee industry in coffee bean exporting countries with current sustainable coffee initiatives such as fair trade or other coffee certification projects. Coffee tourism is not widely discussed in academia, and I argue that this research addresses several gaps in the literature: suggestions for coffee tourism frameworks, coffee tourism research in the context of Ethiopia, coffee tourism research beyond simple analysis in terms of the tourism or coffee industries, and a new illumination on Ethiopian culture, tourism, and coffee culture. Raising the topic of South Korea’s impact in Ethiopia as well as the East Asian role in coffee tourism is also an important contribution to academia. During my PhD tenure, I found a potential global partnership between coffee bean exporting countries and coffee bean importing countries through coffee. Ethiopia is an ideal place for coffee tourism, and it is my hope that coffee tourism could present an approach that brings to light Ethiopia's cultural wealth.

This working paper was developed with the intention to provide a guideline for participatory analysis and development of commercial forest product value chains, in the context of developing countries. Basically, it was designed for identification and implementation of interventions or upgrading measures for the improvement of commercial forest product (Bamboo, Natural gum and resin, and Gum Arabic) value chains in Ethiopia and Sudan within the framework of a collaborative research project - CHAnces IN Sustainability: promoting natural resource based product chains in East Africa (CHAINS). The PIP instrument could also be applied for other commercial non-timber forest products (NTFPs), by adjusting to the local contexts and environments. It can be an important guide for value chain analysts, especially in the process of designing and verifying upgrading actions through the application of tools like interviewing actors, group discussions, or facilitated workshops. This working paper particularly provides: - Background information on basic concepts of value chain analysis and development; - Review of methodological frameworks for participatory value chain analysis and development; - Practical details for participatory value chain analysis as implemented by the CHAINS project, including checklists, diagrams, and tools used in the participatory process; - Critical reflection on the practical application of the approach / Das als Leitfaden gestaltete Arbeitspapier beschreibt Schritt für Schritt das Vorgehen bei der Implementierung von ‚Participative Innovation Platforms‘ (PIP). Das PIP Methodenpaket zur partizipativen Analyse und Entwicklung von Wertschöpfungsketten in Entwicklungsländern wird an Beispielen von kommerziellen Nichtholz-Waldprodukten aus Trockenwäldern Ostafrikas erklärt und gibt praktische Unterstützung zur Durchführung der PIP Workshops mit dem Ziel, Aktivitäten und Interventionen für Innovationen mit Relevanz für die gesamte Wertschöpfungskette gemeinsam mit den beteiligten Akteuren zu vereinbaren. Das PIP Konzept wurde im Rahmen des entwicklungsorientierten Forschungsprojekts CHAINS (CHAnces IN Sustainability: promoting natural resource based product chains in East Africa) entwickelt, um Bambus -, Weihrauch- und Gummi arabicum Wertschöpfungsketten in Äthiopien und dem Sudan zu verbessern. Das PIP Instrument stellt die Akteure in den Mittelpunkt und kann deshalb sehr flexibel auch für andere Produkte angewendet werden. Der Leitfaden bietet: - Hintergrundinformationen zum Konzept von Wertschöpfungsketten; - Einführung in den methodischen Rahmen für partizipative Analyse und Entwicklung von Wertschöpfungsketten; - Praktische Anleitung für die partizipative Analyse von Wertschöpfungsketten nach dem im CHAINS Projekt entwickelten Methodenpaket, einschließlich Checklisten, Diagrammen und Methoden; - Kritische Reflektion zu Möglichkeiten und Grenzen des PIP Methodenpakets.

1989年起，對台灣零售產業發展是一巨大的變革，萬客隆、家樂福等量販店產業的崛起是最具備現代化改革的代表，2000年以後，福元批發倉儲等相繼退出量販店市場，2003年年初萬客隆的停業與高峰百貨2003年年底的跳票倒閉事件更令人震撼，藉由本產業分析的研究期望能對成功與失敗案例背後成因有更深入的了解。 本文中第一章主要說明研究動機、目的、架構與限制，並對部分學者提出的產業分析文獻做一番探討，藉此，突顯與本研究中「產業矩陣分析法」之差異。第二章對量販店產業的定義與其發展沿革做說明，由於量販店所販售的商品與超商、超市、專賣店、百貨公司與甚至傳統市場有所競爭，對於超商、超市、專賣店、百貨公司與傳統市場等本文將其界定為量販店之間接競爭相關產業，文中也做了簡略的介紹，在本章最後說明量販店產業經營時所面臨的種種困難。 「產業矩陣分析法」的應用在於對產業經營流程中所涉及的價值單元(value unit)從投入(input)到產出(output)的產業價值鏈做系統化的分析，第三章主要在界定量販店產業經營流程與產業價值鏈，並對產業中投入部分的價值單元與產出部分的價值單元給予適切的定義。企業的策略需要因應產業環境變化而做適度的調整。「產業矩陣分析法」是從個別企業的立場著手，將產業價值鏈與策略型態構面和產業型態構面交叉分析，透過產業矩陣的應用，將產業分析與策略分析結合，從中為自己所屬的企業找出最適宜之經營策略應是「產業矩陣分析法」之真正精髓所在。第四章是藉由「產業矩陣分析法」來分析台灣量販店產業特性，將量販店產業的產業背景資料一一呈現，就如同一幅產業空照圖，而個別量販店業者要以哪一種策略進入這個寶山，就看個別企業的本事了。 第五章為本文之總結，文中對量販店產業可能的發展趨勢與經營策略做一些整理，並對政府有關單位提出一些建議，也期望對台灣量販店產業的發展有些許的貢獻。 / Since 1989, the development of Taiwan’s retail industry has been through a dramatic transformation with Marko and Carrefour representing the most contemporary innovative changing Hypermarkets. From year 2000 onwards, Fu-Yuan warehouse subsequently disappeared from the Hypermarket industry. At the beginning of year 2003, the stopping of operation of Marko and the closing of Kao-Mart department store represented more shocking news. Therefore the purpose of this study is to conduct an analysis of the hypermarket industry in order to gain a deeper insight of the successful and failed cases of hypermarkets. The first chapter explains the motive , objective, structure and limitation of this study and also gives a brief discussion of the exiting literature of the analysis of the industry through which the uniqueness of “The analysis of the Industry Matrix” could be emphasized. The second chapter explains the definition of the hypermarket industry and the chronicle of the development of the industry. The products sold by convenient stores, supermarkets, department stores and traditional markets are similar to the products of those of the hypermarkets. Therefore convenient stores, supermarkets, department stores and traditional markets are regarded as indirect competitors of those of the hypermarkets .The definition of these above mentioned industries will also be explained. The later parts of this study explain the various difficulties that may be encountered during the operation of the hypermarkets. The main application of “The Industry Matrix Analysis Method” is to systematically analyze every value unit from input to output of the entire industry value chain. The third chapter mainly explains the operation procedure and the industry value chain of the hypermarket industry and also gives the appropriate definition of the input value units and output value units of the industry value chain. The strategies of a firm must be constantly reviewed and changed according to the changing in the industry environment. “The Industry Matrix Analysis Method” is based on individual firms and is used to analyze the strategy dimensional types and industry dimensional types crossly with the entire industry value chain. By means of“The Industry Matrix Analysis Method”, the industry and strategy analysis could then be combined to find out the most appropriate operation strategies of the firms. This is the core spirit of “The Industry Matrix Analysis Method”. The fourth chapter involves using the “The Industry Matrix Analysis Method”to analyze the characteristics of Taiwan’s hypermarket industry and to present the background information of the hypermarket industry as same as the industry’s bird’s eye perspective picture. Which strategies the firm will take and which firms may dominate the hypermarket industry market depending on their own competence. The last chapter includes the summary of this study. The possible future trend and appropriate operation strategies are summarized. Suggestions for the government are also included. The author expects that this study could make some useful contributions for the development of Taiwan’s hypermarket industry.

在數位內容下載市場蓬勃發展的同時，非法傳輸的流量亦不惶多讓，是以DRM機制成為了著作權利人進入網路世界的絕佳後盾，以DRM提高複製的門檻，並據以實施其商業模式，故於各數位內容核心產業皆可見DRM應用之蹤跡，卻同時引發了究竟DRM是Digital “Rights” Management 亦或Digital “Restriction” Management的爭議。是天使？或是惡魔？便形成了人們對於DRM的不同觀感。 本研究係從技術、法律以及管理三個面向分別切入，由技術面看DRM保護著作物之極限何在，由法律面看相關科技保護措施之立法造成何種影響，合理使用的空間是否因DRM之實施而造成限縮，接著由管理面向看DRM在數位內容產業價值鏈中所扮演之角色及其與價值鏈上各端權力角力衝突之關係，最後由標準面看目前DRM相關標準的運作以及互通性標準的發展趨勢。並從個案研究觀察DRM在不同產業情境中的應用。 本研究認為，DRM技術本身是中性的，其關鍵在於商業設計運用。而在盜版問題無法完全根絕之情況下，以DRM作為因應之道將使得受限內容之經濟價值不若自由流通之內容，因為內容產業的發展關鍵在於「人氣」，而盜版永遠無法取代創意與使用者對於內容之需求。因此，既然無法防堵非法傳輸之現象，則不妨與之直接面對面進行作戰，權利人既掌握了關鍵的內容，則可以針對盜版的弱點提供更優質的服務。就我國目前數位內容產業發展之情境來看，現階段或許有採取DRM進行保護的必要性，以便在推動合法消費市場之際，平衡兼顧保護著作權人以及著作利用人之權益。然而，在虛擬世界中欲全面防堵非法散佈有其技術上之侷限性，消費者亦多半養成了免費取得之使用模式與心態，因此長期而言，或許應設法從創新的商業模式來扭轉此態勢。 / Though the use of digital rights management (DRM) has been controversial, it is still widely used in the digital world. Advocates think of DRM as an indispensable way to prevent unauthorized duplication and dissemination of copyrighted works while opponents often suggest that the term “rights” should be replaced by “restriction” to best describe how DRM works. This thesis aims to analyze the issues of DRM from three perspectives. First starting with the technical point of view to see how DRM works and found out that DRM technology does have its limitation for copyright protection. That’s the reason why treaties and legislations such as the WCT, WPPT, and DMCA are needed to build the last ditch in the war with piracy. However, the attempt backfired as companies other than rights holders used it as a way to prevent market competition. As the rights holders can effectively control the access of their work with DRM, there comes another dispute about the “Paracopyright” effect. Most important of all, the use of DRM divests the users of the rights they had in the analog world, such as simply lending a book to a friend. From the perspective of management, a cost benefit analysis indicates that the benefit of using DRM to prevent unauthorized duplication obviously overwhelms by its cost and risk. In the context where the content providers, service providers, and device manufacturers all attempt to dominate the whole value chain, DRM also became one of the most powerful instruments for that purpose. Closed ecosystems are built one after another especially in the online music industry in order to bundle the consumers with specific players and music services and thus caused the antitrust issue. The online music industry and the e-book industry were chosen as case studies in the fourth chapter of the thesis. Based on different industry context, DRM strategy and its impact would differ and therefore results in a variety of business models. For example, the consumers in the US are relatively more aware of the use of DRM and are more willing to pay for authorized content. In contrast, the awareness of DRM of consumers in Taiwan is much lower and the price they are willing to pay is also far lower than what the music labels can accept. As a result, the streaming model prevails over pay-per-download model in the online music market of Taiwan. And the feasibility and necessity of DRM also varies in different industries. Before the digitalization of books, authors already had libraries providing free copies as piracy do today, and the prevalence of scanning machines and copy machines makes it even harder to prevent illegal file sharing. Accordingly, there is far less reason to use DRM in the e-book industry than in the online music industry. DRM technology is neutral in itself, and the key point is how it is designed based on different business models. The defect of DRM is neither a technical nor a legal issue, but rather a business issue. As piracy can never be eradicated, coping it with DRM would only make the value of restricted contents much less than freely distributed contents. Popularity is what really matters in the content industry. DRM has its technical limit and causes so many legal issues accompanied with the cost and risk of maintaining such fragile systems. What rights holders have in hand are the creativity and the market’s need for new content, which could never be replaced by piracy. So why not fight it face to face? Digital content industry is considered one of the most promising industries in Taiwan. However, local consumers have entrenched mindset of “free” contents. In present context, DRM is somehow needed while promoting the growth of legal market, in order to provide sufficient incentive to enrich the society with more and more creativity, and fairly protect both the rights of content providers and content users. But in the long run, a more creative or even subversive business model should be the solution to meet the trend of digital convergence.

本篇論文主要探討新創科技公司產品創新分工網路之現況與績效，新創科技公司之兩大核心資源為創新與技術。公司成長與獲利通常來自技術商品化之價值，一般而言公司很少可完全依賴內部資源進行獨立創新。創新社群以技術為核心，社群中的組織必須顯著地參與一項新技術的商品化工作，主要辨認指標是垂直互補性資產與資訊流通。產業分工網路是企業內部組織和企業彼此間的結合型態，用以產生附加價值，其價值鏈活動是透過良好的協調以造成差異化或成本降低。資訊科技是改變價值活動的執行方式及價值鏈活動中各種連結的性質，影響競爭範圍並塑造新產品。 本研究以國內研發新產品或技術之新創科技公司為研究對象，以個案方式運用分析模式將企業之內外在因素、SWOT及產業能力作深入分析，並訪談中小企業實證研究分工網路活動，探索新創科技公司產品創新分工網路之現況以及產業系統(研究/製造)供應鏈績效，研究結果發現： 1、台灣產業仍屬於「不完全的概念設計與試製生產分離型」分工網路。新創科技公司之產品普遍缺乏品牌形象，且因資源缺乏，無法以全球市場為行銷對象，在設備上的投資、產品與製造的選擇上沒有自主性，限制台灣人才的創新能力及新創科技公司之成功。 2、新創科技公司在產品創新上提昇產品之附加價值，製程上依賴中小企業的「專業分工」及「彈性互補」，充分利用體系資源，調整出最佳效率。但在成熟市場中，採取追隨者的競爭腳步以及成本領導策略，因此無法將產品附加價值回饋於產業分工體系。 3、台灣中小企業普遍在資訊化方面嚴重落後，無法在新的且分散化的產業分工中，以虛擬、組織模組化的分工原理運作，因此人工成本優勢喪失後，其「彈性」、「快速」的核心競爭能力亦在衰退中。 4、中小企業與新創科技公司因價值鏈之市場顧客面不完整，以供應鏈管理觀點檢討發現：管理方法、產品流程、風險與獲利架構、文化與態度觀念、變革升級等構面皆尚待加強。 / I his thesis is mainly in finding out the reality and performance on the network in division of labor for product innovation of a technology startup company. The two core resources of a technology startup company are innovation and techniques. The growth and earning of such company normally come from the value of technology commercialization. Generally, such company could hardly rely on its internal resources completely for independent innovation. Innovative community centers on techniques and the community organization must involve in the commercialization of a new technique significantly, and the main identifying indicator is the vertical complementary assets and the information flow. Industrial network in division of labor is the connecting pattern of the international organization of a business entity with other business, which is for creating added value. The value chain activities are made through sound coordination to generate differentiation and cost-down.Information technology is for changing the performing manner value activities,as well as the natures of connection among various chain activities. It serves to affect the scope of competition and to form new products. This research targeted at the technology startup companies involved in the research and development of new products or new techniques, and case study approach is employed to analyze the internal and external factors of a company,SWOT and industrial capacity with analytical modes. Face to face interview with medium and small enterprises were conducted to empirically demonstrate the activities of the network in division of labor, and to investigate the reality and industrial system (research / manufacturing) supply chain performance of new innovative network in division of labor. The findings are: 1.Industries in Taiwan are still in the stage of“Incomplete Conceptual Design and Pilot Production Separated Network in Division of Labor”level.Technology startup companies are generally lack of brand image. And, with the lack of resources, they are unable to target at the global market for marketing. There is less autonomy in the investment in equipment and options of products and manufacturing. These have limited the talents in Taiwan in their innovation capability and the success of technology startup companies. 2.The technology startup companies promote the added value of their innovative products, and in manufacturing, they rely on the specialization and flexible complement of medium and small enterprise to adjust to the best efficiency by fully utilize the system resources. However, in a matured market, they adopted the follower approach and cost-lead strategies, that they could not feed back the added value of products to the system in division of labor. 3.Generally the medium and small enterprises are having serious information gap, that they are unable to employ the diversification principle in the new and spread-over industrial diversification with virtual, organization modular.Therefore, after losing the labor cost advantage, the core competitiveness in flexibility and speed are also in their way down. 4.Medium and small enterprise, and the technology startup companies have the short of incomplete customer dimension in their value chain, it is found,in the view point of supply chain management, they need to strengthen and improve their managerial approach, product flow, risk and profit structure,culture and attitude and changes and upgrading. Subject Terms (Key Word)： - technology startup company - technology commercialization - network in division of labor - innovation community - value chain - supply chain management

Immense amounts of waste are generated daily by our society, and the management of these streams is a critical societal function. Part of this work is reusing and recycling materials with attractive properties, which is also an imperative step towards circular material flows. Although, the reuse of waste-based resources entails a conflict between efficient use of resources and minimal environmental toxicity, which hampers the reuse. The labeling of a resource as waste also makes using or trading the resource problematic, both regarding regulations, but also concerns from the society regarding toxicity or quality. A way of increasing the reuse of waste streams is initiating and organizing a functioning trade with the material. This study aims at clarifying how new markets for waste base products can emerge and evolve. This aim is formulated as identifying the functions that needs to be fulfilled for a new market for waste-based products to function, and what can be done to fulfill these functions. The study is designed as a case study including four cases where waste in some way is put back to use through trade. This reuse is studied as a market, with buyers, seller and brokers encased in institutions. To expose the role of policy instruments in organizing waste-based markets, there is one specific policy instrument per case for which the effect is analyzed deeper. The main empirics has been collected through interviews with actors on the four case markets, aiming to identify typical events in the evolution of the markets, and what is perceived as important as of today. The case markets are residual sludge from biogas production and from waste water treatment being used as fertilizer, and the residual gravel from waste incineration in Sweden and Denmark being used as a construction material. On these markets, the degree of actual trade varies, as well as the maturity of the markets. By studying and comparing four markets for waste-based resources, and considering the perspectives from actors at different ends of the respective resources value chain, twelve market functions have been identified within three market components. The component institutions and networks contain functions not directly related to the supply- or demand-side of the markets but rather the legitimacy and authorization process, ability of the actors to identify with their roles in the value chain, and how certifications and actor-initiatives can form common grounds for actors in the value chain. In the component supply the waste producer’s responsibility and means of influence over the quality and quantity of the resource is identified as functions. Brokers might play a critical role and policy instruments is needed to increase the producers means of influencing the waste streams, and to regulate the use of the resource. In the component of demand marketing, systems for quality assertion, and niche management are identified as methods to fulfill critical functions. Waste based resources by nature appears as a secondary material flow in a process, and therefore it is not naturally integrated in the business model of any actor. The waste-label forces the resource to comply to rules and regulations perceived problematic, while buyer demands are perceived as unfairly promoting virgin resources and getting societal acceptance of the resource is an uphill battle. By studying the behaviors and needs of market actors, and the role of policy instruments during the course of market evolution, opportunities has been identified as to how policy instruments can fulfill the varying key market functions. For each of the identified functions, it is suggested how policy instruments can contribute, or help the market actors, to fulfill the function. / Idag genereras stora mängder avfall från många delar av det mänskliga samhället och att hantera dessa flöden är en viktig samhällsfunktion. En del i det arbetet är att återanvända och återvinna material med tillräckligt attraktiva egenskaper, vilket är ett viktigt steg i utvecklingen mot mer cirkulära materialflöden. Återanvändning av avfallsbaserade resurser innebär dock en konflikt mellan effektiv resursanvändning och minimering av föroreningar i omgivande miljöer, vilket bromsar återanvändningen. Att ett material benämns som avfall medför också att det blir problematiskt att använda och handla med, jämfört med produktklassade material och varor, både på grund av lagstiftning och ökad oro från omgivningen gällande föroreningsinnehåll och bristande kvalitet. En metod för att uppnå ökad återanvändning av avfallsflöden är att initiera och organisera en fungerande handel med materialen. Denna studie syftar till att utreda just hur nya marknader för avfall kan uppstå och utvecklas, vilket formuleras som att identifiera funktioner som behöver vara uppfyllda för att en ny marknad för avfallsbaserade resurser ska fungera och vad som kan göras för att uppfylla dessa funktioner. Studien är utformad som en fallstudie och omfattar fyra fall där avfall på ett eller annat sätt kommer åter i bruk via handel. Denna återanvändning studeras som en marknad, med köpare, säljare och mellanhänder som omges av institutioner uppsatta av både myndigheter och från annat håll. För att synliggöra styrmedels roll i att organisera en avfallsbaserad marknad har det på varje marknad lyfts fram ett specifikt styrmedel vars roll har studerats mer ingående. Den huvudsakliga empiriinsamlingen har utförts genom intervjuer med respondenter från viktiga aktörer på de fyra marknaderna, vilka har syftat till att både identifiera typiska händelser som har lett till förändringar på marknaderna tidigt i marknadens utveckling och vad som upplevs viktigt på marknaderna idag. De studerade marknaderna är rötrester från biogasproduktion respektive avloppsrening som används som gödselmedel inom jordbruket, samt slaggrus från avfallsförbränning som används som konstruktionsmaterial i samhället i Sverige respektive Danmark. På dessa marknader sker handel i olika stor utsträckning och marknaderna befinner sig i olika skeden av utveckling. Genom att studera och jämföra fyra marknader för avfallsbaserade resurser, och ta hänsyn till behov och perspektiv från aktörer på olika platser i resursernas värdekedja har tolv funktioner identifierats inom tre marknadskomponenter. Komponenten institutioner och nätverk berör funktioner som inte är direkt kopplade till köpare eller säljare. Här presenteras att handel måste vara tillåtet och tillståndsprocessen snabb och förutsägbar, vilket innebär att politiska målsättningar behöver gå i linje med marknadens utveckling. Ytterligare funktioner är vikten av att samtliga inblandade i handeln är medvetna om sin roll i värdekedjan och hur certifieringar och branschinitiativ på ett bra sätt kan skapa naturliga mötesplatser för aktörer i hela värdekedjan. Inom marknadskomponenten tillgång har avfallsproducentens ansvar och rådighet över avsättning och kvalitet och kvantitet hos avfallsflödet identifierats som viktiga funktioner. Mellanhänder kan komma att spela en viktig roll och styrmedel kan behövas både för att öka producenters rådighet över avfallsflödet och för att med avseende på föroreningshalter reglera användningen av det. Inom marknadskomponenten efterfrågan är marknadsföring, system för kvalitetssäkring och spårbarhet samt skapande av nischer identifieras som metoder för att uppfylla betydande funktioner. Avfallsbaserade resurser uppstår till sin natur som ett biflöde till en annan process och är därför inte en tydlig del av någon aktörs affärsmodell. Avfallsklassningen gör också att resursen måste passera regelverk som upplevs problematiska, samtidigt som användares krav upplevs premiera jungfruliga produkter och det finns en förtroendemässig uppförsbacke hos potentiella användare. Genom att studera olika aktörers beteende och behov på marknaderna, samt vilken roll styrmedel upplevs ha spelat under marknadernas utveckling så har möjligheter identifierats gällande hur styrmedel kan uppfylla de olika funktionerna. För samtliga identifierade funktioner presenteras förslag på hur styrmedel kan bidra till, eller möjliggöra för marknadsaktörer, att uppfylla den aktuella funktionen.

L'économie circulaire (EC) émerge depuis les années 2000 dans le débat public, en opposition à l'économie linéaire, modèle dominant aux limites économiques et écologiques reconnues. Cette thèse constitue une première confrontation opérationnelle de l'EC à un système socio-écologique dépendant de la pêche, le Pays de la Cornouaille en Bretagne. Le système est délimité dans sa façade maritime avec la pêche côtière, seule considérée comme production locale.L'approche est systémique, multidimensionnelle et dynamique. L'analyse comporte trois volets : le premier sur l'amont du circuit en mer, le deuxième sur l'aval du système à terre et le dernier sur le système complet. Premièrement, le coût caché des rejets est visualisé via une analyse comptable de flux de matière ("Material Flow Cost Accounting" MFCA) adaptée à la pêche, proposé comme outil pertinent pour améliorer la performance économique et environnementale des pêcheurs. Deuxièmement, l’analyse de flux révèle une forte dépendance des activités à terre vis-à-vis des importations et exportations de bioressources halieutiques malgré un apport significatif de la pêche côtière à l'économie locale. Troisièmement, des scenarii sur le sous-système Sardine, du "business as usual" a l'EC, servent à proposer une trajectoire alternative de développement basée sur un "panier" de biens et services territorialises et la construction d'une valeur territoire à partir de ressources halieutiques locales. Pour atteindre cette EC durable, il s'agira d'optimiser l'utilisation des ressources locales et diminuer les externalités négatives, en plus d'aller vers une gouvernance partagée, adaptée à l'échelle du système socio-écologique considéré. / The years 2000 have favored the emergence of "Circular Economy" (CE) in the public debate, as opposed to the "linear economy", the dominant model that led to acknowledged economie and ecological limits. Our work is a first attempt to address the CE to a fishery-dependent socio-ecological System, the Cornouaille region in Brittany. The approach is systemic, multidimensional and dynamic. It implies the identification of marine boundaries, in which only Coastal fisheries are considered as a local production. The analysis is conducted along three main axes: an analysis of the upstream part at sea (fishing), an analysis looking at the downstream value chain, on land, and a third looking at the whole System. First, a Material Flow Cost Accounting (MFCA) analysis adapted to fisheries is proposed as a relevant tool to improve economy and environmental performance of fishers, providing evidence of hidden costs of fish discards.Second, the fish bioresource flow analysis indicates a strong dependency on importation and exportation flows to maintain land-based activities depending on sea products, albeit evidence of a significant contribution of Coastal fisheries to the local economy. Third, the exploration of the sardine sub-system through scenarii, ranging between from "business as usual" to those lined with CE, shows an alternative development trajectory, based upon a potential "basket of goods and services", a "territorial value", specifically linked to local fisheries. To achieve such a sustainable CE, we would need to not only aim at a more efficient use of local marine resources and decrease negative externalities, but also advocate for a shared governance, suited to the scale of the considered localised socio-ecological System.
