Functions of innovation systems as a framework to understand sustainable technological change: empirical evidence for earlier claims

Understanding the emergence of innovation systems is recently put central in research analysing the process of technological change. Especially the key-activities that are important for the build up of an innovation system receive much attention. These are labeled ‘functions of innovation systems’. In most cases the authors apply this framework without questioning its validity. This paper builds on five empirical studies, related to renewable energy technologies, to test whether the functions of innovation systems framework is a valid framework to analyse processes of technological change. We test the claim that a specific set of functions is suitable. We also test whether the claim made in previous publications that the interactions between system functions accelerate innovation system emergence and growth is valid. Both claims are confirmed.

Understanding innovation system build up: The rise and fall of the Dutch PV Innovation System

Renewable energy technologies have a hard time to break through in the existing energy regime. In this paper we focus on analysing the mechanisms behind this problematic technology diffusion. We take the theoretical perspective of innovation system dynamics and apply this to photovoltaic solar energy technology (PV) in the Netherlands. The reason for this is that there is a long history of policy efforts in The Netherlands to stimulate PV but results in terms of diffusion of PV panels is disappointingly low, which clearly constitutes a case of slow diffusion. The history of the development of the PV innovation system is analysed in terms of seven key processes that are essential for the build up of innovation systems. We show that the processes related to knowledge development are very stable but that large fluctuations are present in the processes related to ‘guidance of the search’ and ‘market formation’. Surprisingly, entrepreneurial activities are not too much affected by fluctuating market formation activities. We relate this to market formation in neighbouring countries and discuss the theoretical implications for the technological innovation system framework.Photovoltaic, Innovation system dynamics, Motors of Change

Unpacking policy processes for addressing systemic problems in technological innovation systems: the case of offshore wind in Germany

While empirical studies on technological innovation systems (TIS) usually focus on policy instruments and their suitability for curing identified weaknesses of such emerging systems, the underlying policy processes and their effects have been largely disregarded. We address this gap by exploring the style of two crucial policy-making processes and how it influences the functioning and performance of a TIS, taking the case of offshore wind in Germany. Our findings indicate important positive and negative impacts of the policy style on the TIS. For example, the muddling through character apparent in one of the policy processes negatively influenced entrepreneurial activities, knowledge development and finally technology diffusion, whereas the participatory nature of both processes had a positive impact both on TIS functioning and performance. Based on our findings we derive implications on how to improve policy making so as to foster the development of an emerging TIS

Understanding circular economy transitions: The case of circular textiles

The circular economy has been proposed to transform global textile supply chains which are currently challenged by a complex nexus of sustainability issues related to the dominant fast fashion trend. Research on circular economy in the textile sector often focuses on businesses or consumers as key enablers in circular transitions, yet it treats them as independent entities and thereby neglects the study of interactions that can provide insight at the systems level. The proclaimed “circular textile mission” in the Netherlands setting a national target for 100% circularity by 2050 is used as case study to address this research gap. We explore the circular textile transition processes found in the context of the Dutch mission and compare the development and interactions among various technical and non-technological solutions produced by engaged actor constellations for assessing key factors driving and blocking the overall mission fulfilment. To these ends, we derive a theoretical framework based on innovation system theory and conceptualize the Dutch circular textile transition as a Mission-oriented Innovation System (MIS). Analyzing the structure and functioning of the Dutch mission-oriented innovation system, we show that (1) there is a good match between the formal Dutch circular textile mission and system actor perceptions; (2) system actors have formed structures around three dominant solution trajectories in the Dutch system: secondhand, mechanical recycling, and chemical recycling; (3) these trajectories expose distinct key virtuous and vicious cycles, which characterize (4) the entire system as formative. Overall, the secondhand trajectory shows most developed structures and most positive dynamics, chemical recycling carries most technological breakthrough potential, whereas mechanical recycling is a mature technology but lacks market demand and supply. We compare the three solution trajectories, discuss the disruptive nature of the Dutch circular textile transition, and suggest installing Extended Producer Responsibility (EPR) as a potential intervention for accelerating system transformation. The study concludes with reflections on the case learnings and considerations for further research on mission-oriented innovation systems

Plant-based protein products in the news: Mind the gap between innovation and public discourses

Markets for plant-based protein products are experiencing unprecedented growth. However, the extent to which the wider diffusion of plant-based protein products is beneficial to human and planetary health is still a contested issue in public discourses. The study of media frames for plant-based protein products can serve as a basis for approaches of technology assessment, which aim to inform actors involved in innovation processes of important aspects of diffusion, including controversy and unexpected risks regarding societal reactions. In this paper, we conduct a frame analysis of three U.K. broadsheet newspapers (the Telegraph, the Guardian, and the Times) between 2010–2020 to explore how media frame plant-based protein products. The results show that overall media coverage for plant-based diets has adopted a positive stance. However, there is variation in how plant-based protein products and particularly meat and dairy substitutes are portrayed. The biggest stumbling block appears to be potentially adverse health implications associated with the consumption of meat and dairy substitutes. We therefore argue that the scope of strategic choices regarding product design should also focus on the development of products more analogous to whole plant-based foods. Moreover, we argue that the long-term resilience of the plant-based protein sector will require strategies that convincingly align with policy goals for food security and broader food system sustainability

A Systemic Assessment of the European Offshore Wind Innovation: Insights from the Netherlands, Denmark, Germany and the United Kingdom

The development and diffusion of offshore wind energy technology is important for European energy policy. However, the large potential does not automatically lead to a large share in future energy systems; neither does an emergent stage of technological development automatically lead to success for companies and the related economic growth and growth in employment. Recent insights in innovation studies suggest that the success chances of technological innovations are, to a large extent, determined by how the surrounding system (the innovation system) is built up and how it functions. Many innovation systems are characterized by flaws that hamper the development and diffusion of innovations. These flaws are often labelled as system problems or system challenges. Intelligent innovation policy therefore evaluates how innovation systems are functioning, tries to create insight into the systems’ challenges and develops policies accordingly. This report assesses the European offshore wind innovation system based on insights from four countries: Denmark, the UK, the Netherlands and Germany. We use the Technological Innovation System (TIS) approach to analyse the state and functioning of the system at the end of 2011. Based on the analysis we identify four types of systemic challenges: (i) actor-related such as deficiency of engineers; (ii) institutional, e.g. non-aligned national regulatory frameworks; (iii) interaction-related like poor transferability of scientific knowledge to specific contexts of application and; (iv) infrastructural such as poor grid infrastructure. We suggest the challenges require a systemic, coordinated policy effort at a European level if the system is expected to contribute to the goals of climate change reduction and stimulation of green growth.JRC.F.6-Energy systems evaluatio

Institutional work as a key ingredient of food innovation success: The case of plant-based proteins

In this paper, we use the theory of institutional work to understand how plant-based meat substitutes emerge and successfully diffuse in the context of a dominant meat regime in the United States (US). We observe that institutional factors such as norms, habits, values, and beliefs play a more vital role than previously identified. Therefore, we utilize institutional work theory combined with insights from technological innovation systems to create a holistic understanding of this transition. We study the American plant-based protein industry from 1978 to 2019. We conduct a qualitative event-history analysis based on 2345 events from the Nexis Uni database. We observe that by strategically deploying institutional work strategies aimed at creating, maintaining, and disrupting institutions and innovation system-building strategies, innovation system actors created a favorable environment in which meat alternatives can flourish

Metabolomic Profile of Young Adults Born Preterm

Prematurity is a risk factor for the development of chronic adult diseases. Metabolomics can correlate the biochemical changes to a determined phenotype, obtaining real information about the state of health of a subject at that precise moment. Significative differences in the metabolomic profile of preterm newborns compared to those born at term have been already identified at birth. An observational case–control study was performed at the University Hospital of Siena. The aim was to evaluate and compare the metabolomic profiles of young adults born preterm to those born at term. Urinary samples were collected from 67 young adults (18–23 years old) born preterm (mean gestational age of 30 weeks, n = 49), and at term of pregnancy (mean gestational age of 38 weeks, n = 18). The urinary spectra of young adults born preterm was different from those born at term and resembled what was previously described at birth. The Random Forest algorithm gave the best classification (accuracy 82%) and indicated the following metabolites as responsible for the classification: citrate, CH2 creatinine, fumarate and hippurate. Urine spectra are promising tools for the early identification of neonates at risk of disease in adulthood and may provide insight into the pathogenesis and effects of fetal programming and infants’ outcomes

Assessing mission-specific innovation systems: Towards an analytical framework

In the currently emerging paradigm of challenge-led and transformative innovation policies, there is increasing attention for addressing urgent societal problems by formulating clear, timebound and ambitious mission goals. Completing such transformative mission's places new demands on innovation systems, as actors and activities need to align around prioritised problem and solution directions. Consequently, new perspectives that support the appraisal of innovation systems’ performance are required for determining what hampers change processes, and which policy responses are appropriate. Following an abductive research approach, this paper aims to develop an analytical framework for assessing mission-specific innovation systems (MIS). We examine three sectoral cases in the mission for a Circular Economy in the Netherlands and propose three analytical steps: 1) a problem-solution analysis, 2) a structural analysis recognising the importance of mission arenas, and 3) a functional analysis addressing directionality provision, coordination, and regime transformation. We conclude with discussing operationalisation and application of the framework

Development and validation of the ID-EC - The ITALIAN version of the identify chronic migraine

Background: Case-finding tools, such as the Identify Chronic Migraine (ID-CM) questionnaire, can improve detection of CM and alleviate its significant societal burden. We aimed to develop and validate the Italian version of the ID-CM (ID-EC) in paper and as a smart app version in a headache clinic-based setting. Methods: The study investigators translated and adapted to the Italian language the original ID-CM questionnaire (ID-EC) and further implemented it as a smart app. The ID-EC was tested in its paper and electronic version in consecutive patients referring to 9 Italian tertiary headache centers for their first in-person visit. The scoring algorithm of the ID-EC paper version was applied by the study investigators (case-finding) and by patients (self-diagnosis), while the smart app provided to patients automatically the diagnosis. Diagnostic accuracy of the ID-EC was assessed by matching the questionnaire results with the interview-based diagnoses performed by the headache specialists during the visit according to the criteria of International Classification of Headache Disorders, III edition, beta version. Results: We enrolled 531 patients in the test of the paper version of ID-EC and 427 in the validation study of the smart app. According to the clinical diagnosis 209 patients had CM in the paper version study and 202 had CM in the smart app study. 79.5% of patients returned valid paper questionnaires, while 100% of patients returned valid and complete smart app questionnaires. The paper questionnaire had a 81.5% sensitivity and a 81.1% specificity for case-finding and a 30.7% sensitivity and 90.7% specificity for self-diagnosis, while the smart app had a 64.9% sensitivity and 90.2% specificity. Conclusions: Our data suggest that the ID-EC, developed and validated in tertiary headache centers, is a valid case-finding tool for CM, with sensitivity and specificity values above 80% in paper form, while the ID-EC smart app is more useful to exclude CM diagnosis in case of a negative result. Further studies are warranted to assess the diagnostic accuracy of the ID-EC in general practice and population-based settings
