The paper explains the commonalities and differences between neoclassical, institutional and evolutionary approaches that have been influential in economic geography during the last couple of decades. By separating the three approaches in terms of theoretical content and research methodology, we can appreciate both the commonalities and differences between the three approaches. It is also apparent that innovative theorizing currently occurs at the interface between neoclassical and evolutionary theory (especially in modelling) and at the interface between institutional and evolutionary theory (especially in 'appreciative theorizing'). Taken together, we argue that Evolutionary Economic Geography is an emerging paradigm in economic geography...
