Fuzzy concepts, scanty evidence, policy distance: The case for rigour and policy relevance in critical regional studies

Comparing with some of the classic texts which addressed the problems of regions and so were located in a concern with real world policy and political engagement, this article contends that these recent tendencies are symptomatic of a body of scholarship that is increasingly abstract. To illustrate the argument, the paper reviews three core areas of work; flexible specialization and its re-agglomeration hypothesis; world cities; and 'cooperative competition' in industrial districts a la Silicon Valley. Ann Markusen makes a claim for an adherence to social science norms of conceptual coherence, causal theory (with both behavioural and structural components) and subjection of theory to the rigours of evidence, where the latter may encompass qualitative as well as quantitative techniques. Greater commitment to entering the policy debate and to making results accessible and informative to real world political activists and planners, it is argued, would substantially strengthen this body of research and its usefulness.
