This special issue aims to contribute to the young academic discipline of European Sociology and focusses its attention towards the transnational (re-)structuration of social spaces and social fields. It includes three contributions that address the European social space (wage inequality, European news coverage and transnational solidarity) and four contributions that deal with social fields (asylum administration, industrial relations, European research funding, and the academic field). In theoretical terms this special issue employs a concept of power relations that draws on Pierre Bourdieu and sociological neo-institutionalism.
