4.1. Characteristics of French and Dutch ERC Winner Projects (RQ1)
The overall distribution of projects shows that The Netherlands has a more balanced representation across SH panels, while France has more concentrated representation in a few SH categories. SH1 is the only panel where France leads (with 23 projects) and it is also one of France’s most represented panels (the other one being SH4). The Netherlands, however, only has four projects in this category, indicating a significantly lower focus on topics related to individuals and markets. In SH2, SH3, SH5, and SH7, the Netherlands has a significant lead (SH2 = 34 − 7, SH3 = 43 − 7, SH5 = 34 − 12, SH7 = 17 − 7). SH4 is unique in the sense that both countries seem to prioritize research related to the human mind and its complexities, but the Netherlands has nearly twice as many projects as France (49 − 27), reflecting a stronger focus on psychological and cognitive research. Research on history, though not garnering grandiose attention in view of the other six panels, is in parity, with both countries being represented by 15projects each. To assess whether the distribution of funded ERC projects across SH panels differs significantly between France and the Netherlands, we performed a chi-square test of independence. The result was statistically significant (χ2 = 51.14, df = 6, p < 0.001), which confirmed that the disciplinary emphases of the two countries diverge in a systematic manner and align with the aforementioned structural differences between the centralized French and decentralized Dutch research models discussed earlier.
From a general standpoint, the Netherlands exhibits a broader and more balanced distribution of projects across SH panels, particularly in areas like governance, social diversity, and cultural production. France, on the other hand, shows stronger representation in specific areas like individuals and markets and focuses more heavily on psychological research (
Figure 3).
Project-wise, the University of Amsterdam was the most successful in the examined period, with 37 grant winning projects among the top 10. The models are well-perceivable through this analysis. The Dutch institutions are exclusively universities, while the French grant-winners are represented through institutions in nearly every instance. The sole counterexample is the Jean Jacques Laffont Foundation, which is operated by the Toulouse School of Economics; however, it can be argued that the Foundation is not within the university’s structured system (
Figure 4).
Based on the semantic topic-modeling approach using BERTopic, we identified four dominant “thematic zones”, alongside a residual category of unassigned or thematically diffuse abstracts. The most prevalent topic, assigned to 133 abstracts, was labeled “Global Research and Cultural Systems”. This semantic theme encompassed work on globalization, cultural transformation, historical systems, and cross-border dynamics in human societies. The second-largest topic, “Cognitive Science and Neural Research,” contained 65 abstracts and focused on neural networks, brain function, cognition, perception, and related psychological mechanisms. This prevalence also aligned closely with SH4, one of the most prominent panels in the SH domain. The third theme, “Political Institutions and Data Analysis,” included 26 abstracts that addressed the interaction between governance, quantitative policy analysis, and data-driven social modeling. These projects frequently referenced voting behavior, regulatory structures, and political decision-making through the lens of empirical data. The fourth topic, “Labor and Economic Structures,” was the smallest in size, with only 11 abstracts. Despite its rather modest scope, this theme was conceptually coherent, with keywords including labor, inequality, job markets, and economic justice. A fifth group of 59 abstracts was classified as outliers or unassigned. These abstracts were unassigned, given that the texts lacked sufficient thematic concentration or were too linguistically diverse to be consistently assigned to one of the four dominant topics.
Thematic distributions across countries revealed distinct research orientations. The Netherlands dominated the “Global Research and Cultural Systems” theme, contributing to over 60% of the total projects in this cluster. France, by contrast, was more evenly spread across the identified themes but had a relatively higher share in “Political Institutions and Data Analysis” and “Labor and Economic Structures.” Both countries contributed almost equally to the “Cognitive Science and Neural Research” theme, which confirms its strong co-alignment with SH4 panel winners’ count. Diving into a more micro-level analysis, we also examined panel-level distribution, which, again, further confirmed the semantic integrity of the derived themes. “Global Research and Cultural Systems” was most strongly associated with SH3 (“The Social World and its Diversity”) and SH5 (“Cultures and Cultural Production”). As mentioned before, the “Cognitive Science and Neural Research” theme aligned almost exclusively with SH4 (“The Human Mind and its Complexity”), as expected, given its domain-specific content. Projects in “Political Institutions and Data Analysis” were concentrated in SH2 (“Institutions, Governance and Legal Systems”) and SH1 (“Individuals, Markets and Organizations”), while the smaller “Labor and Economic Structures” cluster was split between SH2 and SH3. The presence of cross-panel associations within certain themes points to the transdisciplinary nature of the ERC’s funding orientation, especially in the domain of data-driven institutional analysis (
Figure 5).
4.2. French and Dutch Grantees’ Publication Trends (RQ2)
Through descriptive analysis, we first examined the publication trends for French and Dutch ERC winners. Generally, over the examined period, both countries showed an upward trend in the number of publications. Dutch ERC winners consistently published more than their French counterparts, with noticeable peaks in publication output around 2018. For France, the number of publications ranged from 232 in 2014 to 282 in 2018, while Dutch winners showed a broader range, from 531 in 2014 to 684 in 2018.
The French ERC winners displayed a more gradual and steady increase in publication output, with slight annual variations. In contrast, Dutch winners demonstrated sharper fluctuations, particularly between 2015 and 2016, where their publication count increased by over 90. In terms of variance, the Netherlands shows a greater spread in its annual publication numbers compared to France. The average number of publications per year is higher for the Netherlands, underscoring its dominant position in terms of research output among ERC winners during this period (
Figure 6).
The compound annual growth rate (CAGR) reveals significant differences in the publication growth of French and Dutch ERC winners. France shows a modest CAGR of approximately 2.67%, indicating a steady, gradual increase in the number of publications over time. On the other hand, the Netherlands exhibits a much higher CAGR (about 5.42%), demonstrating a more rapid acceleration in research output. This suggests that Dutch ERC winners are experiencing a faster increase in productivity, which could be driven by factors like greater collaboration, funding efficiency, or institutional support. Over the observed period, Dutch winners consistently produced more publications than their French counterparts. In terms of absolute numbers, the Netherlands recorded 1784 publications in the early years compared to France’s 738, and this gap widened significantly in the later years, with the Netherlands producing 5442 publications versus France’s 2028. The substantial growth in the Netherlands points to a potentially more aggressive research strategy, where winners capitalize on their ERC grants to drive publication output. France, while increasing in productivity, shows a slower and more stable trajectory. The faster growth in the Netherlands suggests greater research scalability and responsiveness to ERC funding compared to France (
Table 2).
We have also examined the average co-authorship to achieve a better perspective as to how collaborations account to better research results and eventually winning ERC grants. To do this, we first excluded papers from the publications database that had over 15 co-authors. This resulted in the exclusion of 159 papers in the French segment, and 309 in the Dutch segment, resulting in the removal of 4.7% publications from the dataset.
It is clearly shown that both French and Dutch winners have an extremely strong inclination toward collaboration. In the case of France, the number of co-authors shows a steady growth, from four to five over 10 years. The Dutch trend is interesting too: collaborative publications declined between 2014 and 2016, but have since shown steady growth, approaching France’s 2019 levels over the last 7–8 years. The trendlines also exhibit a strong fit, verifying the above statements on the growing trends in collaborative research (
Figure 7).
In terms of publication volume, both France and the Netherlands demonstrate high output from certain top-tier journals. The French dataset shows that NeuroImage, Scientific Reports, and PLoS ONE are among the most frequently published journals, each exceeding 70 publications. These journals also have relatively high average citations, particularly NeuroImage, which averages over 100 citations. However, there is a noticeable drop-off in citation averages among some of the lower-ranked journals, such as Cortex and Neuropsychologia, which have lower citation counts but still maintain respectable publication volumes.
In the Dutch dataset, journals such as PLoS ONE and Scientific Reports similarly dominate in terms of publication count, each exceeding 100 publications. However, the citation distribution in the Netherlands is more varied. While journals like the Journal of Cleaner Production have an average over 250 citations, indicating significant impact, many of the other top journals have lower average citation counts. This suggests that while the Dutch dataset reflects a high output in terms of sheer volume, the impact (as measured by citations) is more concentrated in a few journals, unlike the relatively more uniform citation spread seen in the French dataset.
These patterns, alongside with the results outlined for the analysis regarding
Figure 6, must also be contextualized by considering the known biases of Scopus in its coverage of SH fields. Both the ASJC category distribution (
Table 3) and topic cluster outputs (
Figure 5) are shaped by Scopus’s indexing. As SH research in France is frequently published in French-language journals—many of which are not covered here—the results likely underrepresent the full thematic range and volume of French scholarship. Consequently, the apparent emphasis on STM-related fields within the SH domain, such as neuroscience or psychology, may be attributed as an “artifact” of Scopus’s indexing practices rather than an authentic representation of disciplinary focus (for this, see
De La Laurencie & Maddi, 2019;
Maddi et al., 2025) (
Figure 8).
Since the sole count of publications in the journals outlined in the analysis related to
Figure 7 may not convert fully the impact of journal choices, we also conducted a statistical analysis of SJR (SCImago Journal Rank) scores and percentiles of the journals preferred by both French and Dutch grantees. SJRs are frequently used in scientometric analyses, since it is a complex metric that is arguably more representative than impact factors or other impact metrics, as it also measures citations depending on the journal’s prominence (i.e., it accounts for both the number of citations received by a journal and the importance or prestige of the journals itself) (
Olmeda-Gómez & De Moya-Anegón, 2015;
Jain et al., 2021;
Schöpfel & Prost, 2009). For this analysis, we analyzed all publications.
The mean SJR (the higher the better) for Dutch publications was 1.94, while the French average was significantly higher at 3.23. The standard deviation of SJR scores was also larger in France (4.12) than in the Netherlands (2.10), and the median SJR scores were 1.41 for the Netherlands and 1.79 for France. For SJR percentiles (the lower the better), Dutch publications had a slightly higher mean (14.61) than French ones (12.98). However, both countries had similar percentile medians (eight for the Netherlands and six for France). These results underline that French researchers tend to publish in slightly more prestigious journals; however, both produce extremely high-quality research (
Figure 8). Normality tests using the Shapiro–Wilk method revealed that none of the distributions were normally distributed (all
p-values = 0.00). As a result, non-parametric Mann–Whitney U tests were applied. These tests confirmed statistically significant differences in both SJR scores and SJR percentiles between the two countries (
p-values = 0.00 for both).
For the ASJC categories, we have filtered out the top 10 most popular categories for both countries. It is important to underline that a single publication can have more than one ASJC. Our research showed that most publications had one–three ASJC categories, but there were also a few publications with nine. ASJCs were analyzed according to their occurrence. A total of 230 ASJC categories were identified.
As can be seen in
Table 3, there is a very strong presence in both countries of research related to psychology, neuroscience, and mental health. In the case of French research, the top ASJC categories are dominated by linguistics (143–140 mentions), while in the Netherlands, the social sciences, in general, dominate (N = 554). In addition to the above categories, sociology, political science, geography, and other related disciplines are also in the top four ASJC categories. The multidisciplinary category is in the top 10 ASJCs for both countries, which suggests that there is a significant spread of inter- and multidisciplinary research (
Table 4).
In the analysis of the topic clusters, 918 topic clusters were identified in the publications database, from which the top 10 topic clusters were filtered by occurrence. Overall, it can be concluded that there is an overlap between the most popular French and Dutch topic clusters, but also important differences. In the case of France, a particular finding is that the thematic clusters do not fully cover the ASJC categorization in terms of their themes; for example, language and linguistics do not appear in the top clusters, while archeology does. The prevalence of functional magnetic resonance imaging was particularly high (N = 411), and this cluster was also prevalent in the Netherlands (N = 307). This topic is perhaps less familiar to those interested in the social sciences; the discipline, also used as an acronym for fMRI, essentially covers neuroimaging techniques used to measure and map brain activity, i.e., it is very closely related to the neurosciences, which are also often included in the ASJC classification. It is also worth mentioning that climate change shows an extraordinary frequency in both the French and the Dutch databases; this clearly suggests that these topics are not only popular but may also contribute to the success of ERC proposals if the “ERC applicant” starts researching such topics. In the case of the Netherlands, it is also important to underline the prevalence of legal and political science topics not found in France, such as democracy and justice, which indicates that, as shown above, the study of regulation and democratic processes is a very prominent theme for Dutch ERC-winning researchers (
Table 5).
4.3. Co-Authorship and Collaboration (RQ3)
The co-authorship network highlights the collaborative relationships among researchers, with each node representing an author and each edge representing a co-authored publication. The central figure in the French ECR winners’ network is Margulies, D.S., whose node is the largest and most connected, indicating their central role in linking various groups of researchers. The Dutch co-authorship analysis shows a more interconnected co-authorship network numerous overlapping edges between the various authors, suggesting a more collaborative research environment where co-authorships span multiple subfields or research teams. The presence of several large clusters, each potentially representing a distinct research group or specialization, is also apparent. It can also be argued that these clusters are connected by key authors, who act as hubs, facilitating communication and collaboration between different groups. Prominent authors like Cardoso, P., Hahn, T., Han H., and van der Ent, R.J., among others, represent a more equally composed network with relatively similar distribution of bigger nodes (
Figure 9).
The centralized French model shows the unarguable dominance of CNRS with 1519 co-authored publications. CNRS’s central role in these collaborations is further supported by its solid FWCI rate of 2.24, reflecting the high impact of its research. Université PSL follows with 746 co-authored publications and a higher citation impact, with 38.2 citations per publication and an FWCI of 2.34, signaling both productivity and influence in ERC-related research. Among the institutions, the Institut national de la santé et de la recherche médicale (INSERM) and Sorbonne Université are notable for their high citation-per-publication figures, with 45.6 and 45.3, respectively.
It is worth underlining that four research institutions made up the top collaborating list, further proving that centralized, research institution-based research can be and is successful in producing and fostering ERC-winning researchers (
Table 6).
The top 10 collaborating institutions with Dutch ERC winners show a strong concentration of academic partnerships within the Netherlands, with only one medical institution, Amsterdam UMC, making the list. The University of Amsterdam leads the chart with 1892 co-authored publications, highlighting its central role in Dutch ERC collaborations. Utrecht University and Vrije Universiteit Amsterdam follow, each contributing over 1200 co-authored publications, underscoring their significant involvement in ERC-related research. Wageningen University & Research stands out with the highest Field-Weighted Citation Impact (FWCI) of 4.39, suggesting that its collaborations produce highly impactful research, despite having fewer co-authored publications than the top institutions. Delft University of Technology also demonstrates high productivity, with an impressive FWCI of 2.71, reflecting the strong impact of its collaborative output. In contrast, Radboud University Nijmegen and Tilburg University have relatively lower FWCI scores of 1.95 and 2.39, respectively, despite their moderate numbers of publications. This suggests that their research may not be cited as frequently in comparison to other institutions in the top 10. The medical sector is represented by Amsterdam UMC, which ranks eighth, with 386 co-authored publications and an FWCI of 2.03, reflecting the increasing interdisciplinary nature of ERC research. Erasmus University Rotterdam, though lower in the number of co-authored publications (416), has a respectable FWCI of 2.44, indicating a balance between quantity and research impact.
Table 7 demonstrates how several Dutch academic institutions play critical roles in ERC collaborations, with varying levels of research impact.
When examining collaborations based on publication information, several similarities have been identified. Firstly, international collaborations play a critical, arguably instrumental, part of the ERC winners’ research dissemination. The rather low national and institutional collaboration rates in both France and the Netherlands also confirm the above statement. Single authorship rates are extremely low. In France, only 11.7% of all publications published by ERC winners are single-authored papers, which is highly similar to the rate in the Netherlands (12.8%).
Collaborative papers also achieve substantially higher citations, especially in the case of international collaboration. It is also to be underlined here that not only is international collaborative research successful in the number of citations, but they are also papers disseminated in top journals, as proven by their exceedingly high FWCI rates (
Table 8).
