Transnationalisation of economies, organisations and societies have fundamentally reconfigured professional life. Dispersal of authority and activity away from national confines has spawned new transnational modes of organisation and competition amongst professionals. Studies of transnational professional competition explore how professionals broker normative, institutional and political change through these struggles in spaces ‘beyond the state’. This paper reviews existing work on transnational professional competition, focusing on two dominant streams: studies associated with Pierre Bourdieu’s field theory and studies associated with Andrew Abbott’s ecological theory. It discusses the key theoretical dynamics and empirical focus of each stream. Furthermore, the paper reviews the ongoing debate between the two streams, drawing out proposals for mutual learning at the intersection of field and ecology studies. It is argued that such a closer exchange has potential to address points of contention and exploit points of convergence, enhancing understanding of specifically transnational professional relations, institutional change, social contexts and social structures.
