The importance of public and private third-party funding of universities has changed over the last decades. However, the knowledge about how universities finance their research are rather limited. We aim to fill this gap and investigate the funding structure of universities and how third-party funding has changed over time. In our explorative analysis, we use publicly available data of four Austrian universities. We analyze this data at university level as well as the level of the faculty of business and economics. We provide insight into the development and structure of third-party funding and conclude that universities’ funding structures differ and has developed over time.
