Doing comparative case study research in urban and regional studies: what can be learnt from practice?

Abstract

Recent years have seen a vivid debate on the epistemological foundations of comparative urban research. Remarkably, comparative case study research practice has remained unaffected by these wider debates and empirical research processes often stay a ‘black box’. Thus, we identify an unmet need for a critical and transparent reflection of conceptual foundations and empirical processes. Based on a review of EU-funded projects in the field of territorial cohesion, we discuss minimum standards of comparative case study research. These standards encompass the theoretical framework of the study, the objective of comparison, questions regarding the ambition to generalize, the case study selection strategy, and potential trade-offs. We conclude that researchers should be more explicit in their way of carrying out comparative research. Eventually, this transparency supports both a fruitful debate on comparative case study designs and the soundness of academic and policy conclusions.
