How Fragmented Are Global Policy Debates on Health Data Sharing? Studying Fragmentation Through Discourse Network Analysis
通过话语网络分析，研究了1995至2019年全球健康数据共享政策辩论的碎片化程度，发现既有集中化也有碎片化趋势，且欧盟在辩论中作用边缘。
Abstract Global policy‐making is often described as taking place in a fragmented and complex institutional landscape. In this article, we revisit the verdict of fragmentation through the lens of discourse network analysis, seeking to understand the extent to which global policy debates can be characterised as fragmented. Examining the case of health data sharing (HDS), an area marked by competing norms and rules, we present results from a longitudinal analysis of the trajectories of HDS policy frames (1995 to 2019). We study discursive fragmentation empirically by analysing three indicators: (1) frame diversification; (2) the increase of conflicting frames (frame contestation); and (3) the emergence of at least three clusters (‘discourse coalitions’) in our networks. We observe that HDS is marked by both centralisation and fragmentation dynamics. We conclude that, despite its self‐portrayal as a global health actor, the European Union has played a marginal role in the debates under scrutiny.
