While economic geography and regional development research extensively cover sustainable innovation and green regional development, innovation diffusion, demand-side aspects, and market emergence are often neglected. This paper illustrates how an enhanced valuation perspective that integrates materiality more directly helps to assess dynamic social processes of valuation in the case of low-carbon, resource efficient solutions. Through a path tracing approach, the paper assesses how two industrial by-products, slag sand and fly ash, evolved into highly valued secondary resources in Germany's Ruhr. Regional availability, market devices, and institutional work influence different dimensions of market valuation in waste-to-value processes. Insights on different phases of the development provide hint on how to organise and foster regional circular solutions. Findings may inform research and policy to advance emerging green industries, market creation for sustainable resources, and industrial decarbonisation, where the materiality of technologies and resources plays a key role.}, language = {en} } @article{ButzinRabadjievaTerstriep2023, author = {Butzin, Anna and Rabadjieva, Maria and Terstriep, Judith}, title = {Anchoring challenges through citizen participation in regional challenge-based innovation policies}, series = {Environmental Innovation and Societal Transitions (Special Issue Geographies of Missions)}, volume = {2024}, journal = {Environmental Innovation and Societal Transitions (Special Issue Geographies of Missions)}, number = {52}, publisher = {Elsevier}, issn = {2210-4224}, doi = {10.1016/j.eist.2024.100856}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1010-opus4-47030}, pages = {1 -- 15}, year = {2023}, abstract = {This study focuses on citizen participation as a co-productive and knowledge-intensive process in innovation policies concerned with regionally anchoring grand challenges. We apply a process-tracing approach and analyse citizen participation in two regional challenge-based innovation policies in the Ruhr, Germany. Local sensemaking, problem ownership, iterations and knowledge co-production are discussed as key mechanisms in the anchoring process. The results reveal the importance of a collective dimension in interpreting the local problem setting of a challenge achieved by reaching out to numerous citizens and how local, corrective and actionable knowledge facilitate the regional challenge anchoring. The policy formulation phase required the highest level of knowledge co-produced with citizens, followed by the implementation phase.}, language = {en} } @article{DavidTerstriepFreiling2025, author = {David, Alexandra and Terstriep, Judith and Freiling, J{\"o}rg}, title = {Rethinking Support Policies: The Role of Belonging in Entrepreneurial Ecosystems}, series = {International Migration}, volume = {2025}, journal = {International Migration}, number = {63 (6)}, publisher = {Wiley}, issn = {0020-7985}, doi = {10.1111/imig.70110}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1010-opus4-48520}, pages = {12}, year = {2025}, abstract = {This article explores the importance of belongingness in migrant entrepreneurs' (MEs) engagement within entrepreneurial ecosystems (EEs), focusing on emotional and social dimensions often overlooked in favour of structural factors. Through two case studies in Germany's Ruhr area, the article demonstrates how a strong sense of belonging enhances resilience, trust and social capital, essential for business success. The experiences of two MEs, Ilyas and Elif, illustrate belongingness as a catalyst for connectedness and embeddedness, enabling access to networks and resources while countering discrimination. The study suggests that policy frameworks should acknowledge and support the emotional and relational aspects of MEs' integration in EEs. Emphasising informal support systems, community engagement and tailored interventions could help overcome structural barriers and foster more inclusive ecosystems. Future research should further examine these dynamics across diverse cultural and geographical contexts to offer a more comprehensive understanding of MEs' entrepreneurial trajectories.}, language = {en} } @article{TerstriepPelka2016, author = {Terstriep, Judith and Pelka, Bastian}, title = {Mapping Social Innovation Maps - The State of Research Practice across Europe}, series = {European Public \& Social Innovation Review}, volume = {1}, journal = {European Public \& Social Innovation Review}, number = {1}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1010-opus4-6573}, pages = {3 -- 16}, year = {2016}, abstract = {In an effort to better understand the various forms of social innovation, mapping has become a common and widely applied method for gaining insights into social innovation practices. The transdisciplinary nature of social innovation research has led to a plurality of distinct approaches and methods. Given the increasing interest in social innovation, and the apparent endeavour among policymakers to utilise social innovation to address current societal challenges, it is argued that mapping efforts need to be streamlined in order to make better use of their results. The article describes 17 ongoing or recently finalised research projects on social innovation and their methodological approaches on "mapping" social innovations.

This paper reframes power as a constitutive, and not incidental, dimension of ecosystem functioning. Integrating insights from Pfeffer's resource-dependence theory with Foucault's and Bourdieu's social perspectives, we develop a Power-Sensitive Entrepreneurial Ecosystem Framework (PSEEF) that conceptualises power across micro (entrepreneurial identity), meso (network structures), and macro (institutional governance) levels. Our key insight is that power dynamics are the hidden mechanisms through which EEs determine who gains visibility and support, and whose ventures remain peripheral. Recognising these mechanisms enables scholars and practitioners to understand ecosystems not merely as collections of resources but as evolving arenas of legitimacy and control. The framework provides actionable tools for ecosystem leaders to diagnose and rebalance inequalities, advancing both the analytical and practical agenda for inclusive and high-performing EEs.}, language = {en} } @article{HamburgO'BrienEngert2013, author = {Hamburg, Ileana and O'Brien, Emma and Engert, Steffi}, title = {Engageing SMEs in cooperation and new forms of learning}, series = {Computer and information science}, volume = {7}, journal = {Computer and information science}, number = {1}, pages = {9}, year = {2013}, language = {en} } @article{NordhauseJanzRehfeldButzin2013, author = {Nordhause-Janz, J{\"u}rgen and Rehfeld, Dieter and Butzin, Anna}, title = {Indikatoren zur Innovationst{\"a}tigkeit am Bau im internationalen Vergleich}, series = {BMVBS - Online-Publikation}, journal = {BMVBS - Online-Publikation}, number = {8}, publisher = {Bundesministerium f{\"u}r Verkehr, Bau und Stadtentwicklung}, address = {Berlin}, year = {2013}, language = {de} } @article{ButzinRehfeld2013, author = {Butzin, Anna and Rehfeld, Dieter}, title = {The balance of change and continuity in the German construction sector´s development path.}, series = {Zeitschrift f{\"u}r Wirtschaftsgeographie}, volume = {57}, journal = {Zeitschrift f{\"u}r Wirtschaftsgeographie}, number = {1-2}, pages = {15 -- 26}, year = {2013}, language = {en} } @article{HamburgO'Brien2013, author = {Hamburg, Ileana and O'Brien, Emma}, title = {E-learning 2.0, social media and communities to improve knowledge in companies}, series = {Service science and management research}, volume = {2}, journal = {Service science and management research}, number = {3}, pages = {33 -- 38}, year = {2013}, language = {en} } @article{O'BrienHamburg2013, author = {O'Brien, Emma and Hamburg, Ileana}, title = {Organisational problem based learning and social communities for SMEs}, series = {European journal of open, distance and e-learning}, volume = {16}, journal = {European journal of open, distance and e-learning}, number = {2}, pages = {50 -- 60}, year = {2013}, language = {en} }
