Unlocking Cluster Investment Attractiveness: A Multi-Case Study Analysis of Patenting, Publishing, and University Proximity

Abstract

In a world marked by rapid technological advancements and environmental concerns, clean technology clusters have become hubs of innovation. Attracting investment in these clusters has gained significant attention from scholars and industry professionals, which aim at understanding which activities companies can undertake in order to increase the attractiveness of the cluster and region.
This study explores the factors influencing investment attractiveness in clean technology clusters, focusing on company-level variables like patenting activity, publishing activity, and proximity to universities.
Using a case study approach, the research analyzes four Western European clean technology clusters, aiming to uncover insights and differences in investment attractiveness. The four clusters are Aclima (Basque Country, Spain), CLEAN (Central Region, Denmark), Greenreality (South Karelia, Denmark) and Water Alliance (The Netherlands). The analysis is divided into the single case reports for each cluster, exploring the variables at the company level, and into the cross-case analysis, bring the previous observations together at the cluster level.
The findings highlight the positive impact of patenting activity on cluster attractiveness for the clusters under study. While no distinct relationships were found for publishing activity and university proximity, the cluster-level additional factors in consideration provided useful identifying some potentially meaningful differences between the clusters, such as the approach and recognition of their regions and countries toward sustainability.
However, the study also acknowledges its limitations, mainly stated as the availability and quality of data, as well as some methodological decisions on the assessment of investment attractiveness, suggesting future research opportunities in this dynamic field. From elaborating a more refined iteration of this study to approaching new topics, the findings and limitations of this research invite future researchers to enrich the body of knowledge associated with clean technology clusters, and in particular with their funding dynamics.
The implications of this study mainly concern the positive influence of patenting on the attractiveness of companies and clusters. Pursuing and supporting this kind of intellectual protection activity could prove to be a powerful tool for firms and cluster managers.
