The Lens
The hidden engine behind business school reputation
Behind every leading business school brand lies a less visible driver: research. The latest QS rankings reveal how intellectual output not only informs reputation, but sustains it.

"The credibility of business education ultimately depends on the knowledge being created inside those institutions."
"Reputation may attract attention, but research is often what sustains credibility over time."
In brief
- Research is the "hidden engine" of business school prestige, acting as a less visible but vital driver that sustains global brand reputation and long-term academic credibility.
- Ranking data reveals that high-impact research reinforces teaching quality and policy influence, proving that intellectual output is what ultimately validates a school’s standing among employers and peers.
- To maintain substance over branding, institutions must prioritise rigorous knowledge creation. This legitimises funding and ensures students learn from faculty who are actively shaping future industry trends.
Fifteen years after the first QS World University Rankings by Subject were published, the Business & Management ranking has become one of the clearest snapshots of how the global business school landscape is evolving.
At its core, the methodology balances two forces that do not always sit comfortably together: reputation and research. The indicators are familiar. Academic reputation, employer reputation, citations per paper and the H-index.
Yet their combination raises a question that still sparks debate inside business schools themselves. Should management education really be judged on research at all? To explore that question for this year’s release, I contacted a handful of research leaders and deans from leading schools around the world to ask how they view the relationship between research, reputation and business education.
Their answers highlight a shared view. The credibility of business education ultimately depends on the knowledge being created inside those institutions.
As Elena Carletti, Dean for Research at Bocconi University in Italy, explains: “Research impact is a significant indicator because it measures not only how many publications a university produces, but also the extent to which those publications influence other scholars, decision-makers and real-world practice.”
That thinking sits at the heart of the QS methodology. Business schools are not only teaching organisations. They are also generators of ideas that influence how markets, organisations and public policy evolve.
Professor Bert De Reyck, Dean of Singapore’s SMU Lee Kong Chian School of Business, puts it simply: “Producing high-impact research is a core mission of a business school… evaluating how that research advances the thinking in the field and how the research impacts industry, policy institutions and society is key to assessing business schools globally.”
A decade and a half on, the subject ranking has therefore become something more than a league table. It provides a lens on how influence in business education is built through ideas, evidence and intellectual leadership.
The 2026 results illustrate this dynamic in several interesting ways. The familiar leaders still appear near the top of the table, but the underlying indicators reveal how reputation and research reinforce one another.
INSEAD in France, ranked 4 globally, continues to combine exceptional academic reputation with strong citation performance, reflecting its position as one of the most internationally influential research environments in management. Bocconi University, ranked 10 globally this year, offers another example. Its strong academic reputation is closely aligned with research influence, underlining the growing role European research universities now play in shaping global management debates.
Further down the top 20, Spain-based Universitat Ramon Llull, home to ESADE Business School, stands out with one of the strongest citations per paper scores among the leading schools. This highlights how focused research strength can elevate an institution into the global conversation.
Copenhagen Business School presents another interesting case. The Danish institution’s research influence is extremely strong, yet its employer reputation score is more moderate, suggesting that research recognition can sometimes move faster than market perception.
Taken together, these patterns highlight a deeper dynamic behind the ranking results. Reputation may attract attention, but research is often what sustains credibility over time.
“Research impact is not about publication volume, but about whether knowledge changes understanding and practice… it reveals whether a school is truly operating at the frontier of knowledge,” says Juan Santalo, Vice Rector for Faculty and Research at IE University in Spain.
Institutions that consistently generate influential ideas become reference points in global discussions about artificial intelligence, sustainability, digital transformation and economic growth.
Colin Higgins, Deputy Dean of Australia’s Deakin Business School, frames this clearly: “Strong research performance enhances a business school’s reputation because it signals intellectual leadership. Schools that consistently produce high-quality research shape the global conversation about how organisations should operate and how economies need to evolve.”
The QS indicators therefore capture more than brand visibility. They show which institutions are influencing how business is studied, understood and practised.
For students, the relationship between research and reputation has practical consequences. As a member of the AACSB Global Research Impact Task Force, an initiative working to redefine how research impact is evaluated in business education, I argued at last year’s AACSB ICAM conference that research indicators in rankings can serve as a useful proxy for teaching quality.
The indicators reveal whether a school’s intellectual environment is active, rigorous and forward-looking. When faculty members are producing influential research, students are not simply learning established frameworks, they are exposed to new thinking that is still being tested and debated.
Professor Jochen Wirtz, Vice Dean of MBA Programs at NUS Business School, in Singapore highlights this connection between research and the classroom: “Research is arguably the strongest indicator of the quality of its faculty and their thought leadership. It shows that a school is at the cutting edge of its chosen fields and leads the discussion.”
Yet strong research does not automatically translate into reputation or impact. “Strong research performance does not guarantee that a school's reputation will be enhanced nor that the work will be relevant, but it does give rise to a culture of rigorous inquiry that will appeal to non-academic partners who know there are no easy answers or shortcuts to addressing the complex business challenges we face today,” says Ha Hoang, Associate Dean for Research at France-based ESSEC Business School.
Leila Alinaghian, Director of Postgraduate Programmes at UCL School of Management, similarly highlights the intellectual benefits of that environment: “When faculty produce rigorous and impactful research, it creates dialogue within the scholarly community and enhances the school’s reputation… it strengthens the intellectual foundations of teaching and supports a more critically enriched educational experience.”
The most successful business schools therefore operate at the intersection of ideas and practice. Their research informs how organisations operate, their insights influence policy debates and their teaching prepares students for a business environment that is constantly evolving.
The Business & Management ranking highlights a reality that is sometimes overlooked in discussions about management education. The schools that build the strongest reputations are often those that are actively shaping the ideas that define business itself.
What emerges from this year’s results and from these conversations is a clearer sense of what rankings are really capturing. As Professor Sarah Ashwin, Head of Management at LSE in the UK, argues: “Rankings that ignore research impact risk rewarding branding over substance.
“Strong research performance and real-world relevance reinforce each other: when research consistently informs how organisations are led, how markets are governed, and how corporate strategy responds to disruption, it earns authority with the executives and policymakers who shape the world our students will enter.”
This also speaks to a broader public dimension. Chrysoula Papacharalampou, Executive Director at the Erasmus Research Institute of Management, notes that research performance is “an excellent way to legitimise to the public how the funds allocated for research purposes have been utilised for the creation of new, relevant knowledge for society,” while also strengthening a school’s ability to attract the next generation of researchers.
Rankings such as those by QS therefore do more than compare institutions. They highlight where ideas are being developed, tested and applied. And in doing so, they remind us that in business education, reputation may be visible, but it is research that gives it meaning.
