- Participation has been studied from different points of view. One of the possible ways to address the topic is to interrelate it with cultural consumption, con- sidering the relevance of both terms with regard to social cohesion and integration. The essay is designed to evaluate the interaction between participation and cultural consumption, leading to a definition of some citizens' groups with homogeneous features compared to both variables. Moreover, the essay aims to examine the groups' behaviour, compared with a phenomenon related to both cultural consumption and socio-political participation: responsible consumption. The groups' behaviour relative to this variable helps the understanding of some social dynamics and, above all, highlights the close relationship between a particular group (the actives) and alternative consumption behaviours. A thorough analysis of the relationship between a high degree of cultural consumption and a high degree of political participation underlines that responsible consumption is a collective action and, at the same time, finalised to and endowed with political efficacy.Keywords: Political Consumerism, Participation, Cultural Consumption, Collective Action, Political Efficacy.
