The digital transition has become a crucial area of ideological contestation, as ongoing debates on digital surveillance and data commodification exemplify. Yet, we know too little about how political parties tap into these confrontations. This article elaborates a critical approach to map the ideological positions that 25 parties in France, Germany, Italy and Spain adopt on platform societies. The empirical analysis classifies parties' positions to uncover how their views on the digital economy and digital politics reshape their core ideologies. While parties are distributed along six ideological positions, most cases populate three types: Platform Neoliberalism, Social Liberalism 4.0 and Platform Socialism. These types represent the tripartite ideological divide on platform societies. Ultimately, this study provides an empirically informed theory of comparative digital politics and the foundation for research agendas on political parties' views on digitalization and the relations between ideologies, public policy and parties' organizational change in the digital age.

Systematic accounts of East Asian government responses to the ‘limits of productivist regimes’ (Gough, 2004) remain surprisingly rare. This article develops three distinct types of East Asian welfare development, i.e. quantitative, type-specific, and radical, employing set-theoretic methods. It then uses these types to analyse six policy fields, including education, health care, family policy, old-age pensions, public housing, and passive labour market policy, in six East Asian societies: China, Hong Kong, Japan, Korea, Singapore and Taiwan. We find that all cases except Hong Kong and Singapore have experienced at least one radical shift in their welfare models over the past three decades (1990–2016). East Asian governments have increasingly combined quantitative expansion or retrenchment of ‘productive’ and ‘protective’ policy structures but have done so in unique ways. South Korea has followed the most ‘balanced’ approach to welfare development and stands out as the best candidate for further type-specific expansions moving forward.
