Publication pressure is perceived to be filtering down into doctoral education worldwide. We explore the causes and effects of the perceived centrality of publishing among doctoral students, emphasising the impact of publication pressure on students' identity trajectories. We draw on a qualitative analysis of 90 mainland Chinese doctoral students at universities in mainland China, Hong Kong, and Macau. We find that the credentialisation of publications in the increasingly competitive and publication-dominant academic labour market results in publishing-centred doctoral journeys. Our key finding is that the centrality of publishing affects every aspect of identity trajectory development: it causes doctoral students to commodify knowledge production, devalues coursework, conference participation, and teaching assistantships, encourages students to regard their supervisors as publishing facilitators and their peers as rivals rather than collaborators, and marginalises engagement with external stakeholders. In discussing these dimensions, we emphasise the need for a more comprehensive evaluation of candidates' abilities and honours in academic recruitment and call for policies to curtail the overemphasis on research output in academic evaluations.
