German-Language Spatial Planning Research between Theory and Practice.

This paper examines two leading questions of current German spatial-planning-research. The first question regards the significance of co-authorships in German-language spatial planning research, measuring the extent of interdisciplinarity and cooperation. Compared with other disciplines, stable co-authorships have less importance. The second question pertains to the role of theoretical bases in the journal articles: Large parts of publications in spatial-planning-journals have minimal theoretical foundations. Therefore, even as a practice orientated discipline , spatial planning research must improve the process of knowledge production, such as by building stable co-authorship-networks and a better theoretical foundation of its empirical work.
