The research subject of the paper is the spatial agglomeration phenomenon in tourism – the
concentration of firms registered in the tourism sector, including both types of the agglomeration
economies: localization- and urbanization-driven clusters. Agglomeration phenomenon is measured
on the basis of statistics within regional administrative boundries. In tourism it is crucial to capture
spatial dependency between the phenomena in neighboring regions outside the boundries, hence
there is a need to capture geographic spillovers – as proposed in the paper by applying local
indicators of spatial association.
We used the data collected by the Central Statistical Office in Poland and Germany at NUTS-4
and NUTS-3 level. In order to study the spatial concentration of the tourism sector and its linkages
with neighboring regions we used location quotients and the methods of the explorative spatial data
analysis. The study have revealed that Moran’s I statistic is sensitive to the measures of the
neighborhood identification and localization of the territorial units boundaries.
