FROM INVESTMENT TO EXCELLENCE? EXPLORING THE RELATIONSHIP BETWEEN R&D SPENDING AND QS TOP 500 UNIVERSITY PRESENCE ACROSS COUNTRIES IN 2022

Abstract

The main objective of this paper is to examine the relationship between higher education and a country’s socio-economic development by analysing national investment in research and development as a share of GDP and its association with higher education quality, as reflected in global university rankings.
The relationship between research investment and university rankings has been explored, with numerous studies underscoring the pivotal role of research and development (R&D) funding in shaping academic and institutional performance. Van Vught, F., & Ziegele, F. in 2013 criticized the existing university rankings for focusing too narrowly on research, leading to a negative effect on the diversity of higher education institutions. As Hazelkorn concluded in 2009, by using a particular set of metrics to highlight research as the key proxy for higher education quality and excellence, rankings are helping to reshape higher education and reconstruct our understanding of what is research/knowledge production and who/which institutions should contribute. In international contexts, disparities in R&D investment have significant implications for university rankings. Farrell et al. (2006) observed that the EU lags the US and Japan in R&D expenditure as a percentage of GDP, while Cimini, Zaccaria, and Gabrielli (2016) noted that developed nations, despite financial crises, have generally increased R&D investments, leading to improved scientific performance.
The literature demonstrates a strong correlation between research investment and university rankings. While increased funding supports research output and institutional reputation, ranking systems are widely criticized for overemphasizing research performance and being controlled by private, for-profit entities. Given this emphasis, higher national investment in research and development is assumed to enhance universities’ research output and, consequently, their position in global rankings, despite persistent structural biases and inequalities within ranking methodologies.
Pearson’s correlation analysis was used to examine the relationship between the number of QS Top 500 universities and national investment in research and development (R&D). The results show a statistically significant moderate positive correlation at the 0.01 level (two-tailed), indicating that countries with a higher number of top-ranked universities tend to allocate a larger share of their GDP to R&D. While the relationship is not strong, it is meaningful and unlikely to have occurred by chance, supporting the hypothesis of a positive association between research investment and global university standing. These findings align with existing literature, which highlights the role of research funding in strengthening academic output and institutional reputation, while also acknowledging persistent systemic limitations such as disciplinary bias, linguistic barriers, and unequal resource distribution. Overall, the results underscore the importance of sustained research investment in shaping both national innovation capacity and global academic competitiveness.
