Editorial introduction Demography of the firm and spatial dynamics.

The article introduces a series of articles on the links between firm dynamics and spatial dynamics. It shows the different aspects of the relationship. The papers show the multi- and interdisciplinary nature of the topic of firm demography. The range of topics covered includes entrepreneurial studies, firm start-ups, firm exits and business relocations. Although all the papers deal with spatial variation in terms in the sense of differences between regions or countries, some deal explicitly with the spatial dimension of firm geography in the sense of distance sensitivity. Regional growth and agglomeration economies figure importantly in the papers as well, as the outcome of firm dynamics at the micro level. The relatively large number of papers dealing with new firm formation reflects the focus on the demographic component in the field of firm geography in general.
