That's a very interesting topic. I can suggest two directions.
The first one is to go formal and use the Herfindahl index, for which you need estimates of the market shares of higher education institutions.
The second is to make a broader (and more qualitative) analysis, e.g., using Porter's Five/Six Forces framework of factors affecting the competitive rivalry in the market.
Given that, I'd suggest being careful in defining "higher education". E.g., what types of education institutions and levels of education are included in the analysis and whether the analysis should be based on the whole market vs. dividing it into submarkets.
You might also be interested in the related work, e.g., of Simon Marginson, see the attached links.

Is it a case study type of research? because higher education is very broader concept. Have you considering particular field, branch, faculty (eg. science, medical, education. law etc.)? please consider following points while frame your research
1. Ratio of Applications and actual seats available (vacancies)
2. increase in fees.... year by year (is the rate is same in each field?)
