The multiple-theories problem: The case of spatial industrial clustering

Abstract

Multiple theories of the same phenomenon abound in many interdisciplinary research areas, but it is often unclear how the theories relate, and there are no clear guidelines for dealing with this plurality. The history of research on spatial industrial clustering is a case in point. We identify a number of solutions to the problem of multiple theoretical accounts proposed in this literature. We label them definitional, taxonomic, integrative, and multi-perspectival. We then offer the erotetic solution as an indispensable complement to any attempt at resolving the multiple-theories problem. It accounts for theoretical plurality in terms of different explanation-seeking questions different theories aim to address. We analyse three prominent explanations in the recent history of research on spatial industrial clustering and show how the erotetic approach can contribute to foster interdisciplinary dialogue.
