Authorship, as a form of professional recognition, is an important topic in the study of reward systems in science. Empirical studies have shown that reward systems in science vary by historical periods and institutional contexts. Yet existing theoretical perspectives prove inadequate in explaining these variations. This study extends existing literature by investigating organizational mechanisms that shape “cycles of credit” in science and local institutional logics of authorship practices. Qualitative analysis is primarily based on in-depth interviews with thirty-one life scientists from (...) an elite and a provincial university in China, a country that has undergone unparalleled growth in scientific productivity in the past decade. I identify two different institutional logics of authorship. In the elite university, a logic of “autonomy” prevails. Researchers tend to remain independent and equal in negotiated coalitions and give coauthorship credit based on individuals’ scientific contributions to each paper. By contrast, in the provincial university, a logic of “dependence” prevails. Research teams assign coauthorship credit based on members’ long-term contributions regardless of whether they are scientific or not. Organizational factors, including historical development path, resource distribution pattern, and incentive scheme, are crucial in shaping and maintaining these divergent logics. (shrink)
