Successful transitions to a sustainable bioeconomy require novel technologies, processes, and practices as well as a general agreement about the overarching normative direction of innovation. Both requirements necessarily involve collective action by those individuals who purchase, use, and co-produce novelties: the consumers. Based on theoretical considerations borrowed from evolutionary innovation economics and consumer social responsibility, we explore to what extent consumers’ scope of action is addressed in the scientific bioeconomy literature. We do so by systematically reviewing bioeconomy-related publications according to (i) the extent to which consumers are regarded as passive vs. active, and (ii) different domains of consumer responsibility (depending on their power to influence economic processes). We find all aspects of active consumption considered to varying degrees but observe little interconnection between domains. In sum, our paper contributes to the bioeconomy literature by developing a novel coding scheme that allows us to pinpoint different aspects of consumer activity, which have been considered in a rather isolated and undifferentiated manner. Combined with our theoretical considerations, the results of our review reveal a central research gap which should be taken up in future empirical and conceptual bioeconomy research. The system-spanning nature of a sustainable bioeconomy demands an equally holistic exploration of the consumers’ prospective and shared responsibility for contributing to its coming of age, ranging from the procurement of information on bio-based products and services to their disposal.
Innovations incorporating environmental and social considerations can address many sustainability challenges. Such sustainable innovations emerge in networks often comprising actors from business, academia, civil society, and government. The crucial interactions here are the (co-)creation and transfer of knowledge, mutual learning, and experimentation in different environments. To better understand these knowledge processes and hence the eventual outcome of sustainable innovations, we analyze the actors’ relationships with the help of proximity and its five dimensions, namely geographical, cognitive, institutional, organizational, and social proximity. Building upon findings from sustainability science and innovation system theory, we present a refined proximity framework, introducing a differentiation of institutional proximity into micro- and macro-institutional proximity and a differentiation of cognitive proximity into systems-cognitive, normative-cognitive, and transformative-cognitive proximity. Analyzing examples from the literature by applying this framework, we see that all proximity dimensions and their interdependencies help to better understand knowledge processes and innovations in sustainability-oriented innovation networks. We find that such networks often depict low levels of micro-institutional and systems-cognitive proximity, which coheres with the prevalence of inter- and transdisciplinary approaches and the wide inclusion of relevant stakeholders for addressing sustainability issues. Our framework further reveals that successful networks show high levels in other proximity dimensions, with normative-cognitive proximity appearing to play a crucial role, highlighting the importance of shared goal orientations. Our results provide valuable input for the formation of sustainability-oriented innovation networks by pointing out the necessary combination of distances that allow for creativity and learning, combined with appropriate proximities for exchange and mutual understanding.
Innovations can substantially contribute to the transformation toward sustainability if they induce a positive social and/or environmental impact. Such sustainable innovations differ considerably from conventional, purely economic innovations. The main difference stems from the different knowledge bases necessary for the development of these innovations. These knowledge bases are widely dispersed across different actors from business, academia, government, and civil society. Following the innovation system approach, we look at actor constellations, linkages between actors, and knowledge flows within networks that generate sustainable innovations. For this purpose, we conduct a systematic literature review, focusing on the concept of proximity and its five dimensions (geographical, cognitive, institutional, organizational, and social proximity). The results show that all proximity dimensions, as well as the interdependencies between them, are relevant for analyzing knowledge flows leading to sustainable innovations. The interplay of the different proximity dimensions can be described via two mechanisms, one being reinforcement and the other one being either substitution or overlap. We conclude that for the occurrence of radical, systemic innovations, which have the potential of altering the prevailing socio‐economic paradigm toward greater sustainability, a combination of low cognitive and low (micro‐) institutional proximity combined with high organizational, social, or geographical proximity, appears particularly conducive.
