Abstract
Existing research on tourism spatial planning primarily focuses on different political and economic systems (PESs)—but most often within capitalist democracies. However, there is a lack of research examining how frequent changes in PESs (capitalism, socialism and recapitalism) act as critical points, as they affect tourism spatial planning legislation, land use and spatial management. By analysing the spatiotemporal evolution of the Kupari tourist zone in Croatia (1880–2024), we investigate how PES changes act as critical turning points that shape tourism spatial planning and administrative practices. Key results reveal that tourism recovery and resilience are closely linked to the stability of PESs. Frequent PES changes (1) reduce the overall resilience of tourism and its institutions, (2) lead to recurring changes in tourism spatial planning legislation (e.g., ownership and land use) and (3) disrupt the positive correlation between space and tourism development. Frequent changes in PESs are reflected in legislation, as well as in challenges of compromise for issues closely related to tourism and spatial management. Only a stable PES can enable continuous monitoring of legislation and its spatial consequences in real time. An integrated methodology for monitoring legislation, together with a framework for spatial management, offers practical solutions for the sustainable management of tourist areas. These findings provide both scientific evidence and practical strategies for better harmonization of legislation with the resilience of tourism spatial planning on the eastern coast of the Adriatic Sea.
