This thesis examines the strengths and weaknesses of the municipal structural reform in Styria by analysing the municipal merger of Liezen and Weißenbach. Until the turn of the year 2014/2015, the Styrian government worked intensively on implementing the reform with the aim of reducing the number of municipalities from 542 to 287. Research in the study area showed, that this reform was not only positively received by the stakeholders. Disputes challenged both, large parts of the local population as well as a national institutional body, the Constitutional Court.Within the seven chapters of this thesis, the challenges of structural reform are determined, using literature research and archive work as well as media and interview analysis. The qualitative analysis is based on P. Mayring's category-based content analysis and provides information on the diversity of actions during the disputes.An action theory-based approach to the concept of space builds the theoretical basis for the spatial conflict analysis. What is understood as space and how space is constituted, is dependent on the different research approaches in social geography. The definition of space used in this work is mainly based on research by B. Werlen and P. Reuber. The actors participation in co-designing and shaping the common living space is the focus of this thesis.The results of the content analysis of the four interviews show a much differentiated picture, as different perceptions, appraisals and instrumentalisations of spatial structures are determined by the actors. The analysis is embedded in a research on past territorial reforms as well as on an analysis of media published in the time during the reform process. A summary of the results and an outlook into the future will be presented at the end of this thesis.
