Collaboration, Integration, and Thematic Exploration in European Framework Programmes: A Longitudinal Network Analysis

TL;DR

This longitudinal study analyzes European Framework Programmes data to understand collaboration networks, research topic evolution, and knowledge exploration, revealing increasing integration but persistent core-periphery asymmetries.

Contribution

It provides a comprehensive analysis of the evolution of collaboration networks and research themes in European funding programs over time, using semantic embeddings and network metrics.

Findings

Collaboration networks show increasing equity but marginal countries remain on the periphery.

European research explores a wider knowledge space over time, but focus remains uneven across topics.

European research is concentrated along established trajectories, with limited broad exploration.

Abstract

Since their inception in 1984, the European Framework Programmes (FPs) have funded collaborative R&D to promote excellence, cohesion, and competitiveness in a growing European Union. However, their integrative impact and the evolution of the research landscape alongside its collaborative structures remain insufficiently understood. In this longitudinal study, we leverage CORDIS data from all nine FPs to reconstruct the evolution of country-level collaboration networks over time. We observe an increasing equity in project participation between FP1 and FP6, although newly included countries systematically tend to be marginal when first joining the programmes. However, we find that the collaborative nature of EU projects progressively integrates marginal countries in the network, even if this integration is still in progress. We also trace the evolution in time of research topics using semantic embeddings of project descriptions, identifying 117 topics grouped into 16 macro-topics. By computing the minimum spanning tree length of project embeddings within yearly time windows, we quantify how European research progressively explores a wider knowledge space. A comparison with a null model with points randomly distributed in the semantic space indicates that this exploration is more focused than a uniform coverage. Moreover, it appears uneven, with few topics mostly attracting industry and others academia. Our findings suggest that, while European funding promotes international cooperation, it has not yet fully resolved core-periphery asymmetries, and European research remains concentrated along established trajectories rather than broadly exploratory, with implications for future programme design and the excellence-cohesion debate.
