Abstract
Analyzing postgraduate theses is crucial for identifying scientific trends, development processes, and future directions. While second-home research has expanded globally, a systematic synthesis of the field’s 30-year evolution in Türkiye remains a gap in the literature. This study reviews postgraduate theses to identify the current state of research and gaps in second-home tourism. The primary data source for the study consists of theses 'Second Homes' retrieved from the CoHE Thesis Center. This research analyzed 40 postgraduate theses. The existing literature has predominantly focused on the impacts of second homes. In the international literature, however, research is diversifying by expanding into different destinations, such as mountainous and lakeside areas, and by deepening its focus through contemporary concepts like nostalgia and gentrification. Future studies focusing on local, specific, and in-depth effects unique to second homes— such as effects on the construction sector and on employment— rather than on general tourism impacts will provide a critical contribution to filling this gap in the literature.
